How are Specialty LiPo Batteries Made?

 specail thin Shaped Battery

Grepow’s Lithium-ion polymer (LiPo) batteries can be specially made to be ultra-small, curved, and ultra-thin–the possibilities are endless! With factories in China that specialize in battery production, Grepow has only continued to grow and work to keep to the high performance expected of its batteries.

We will briefly explore some aspects of the production method of how thesespecialty LiPo batteriesare made at Grepow’s factories.

custom battery manufactures

Temperature and humidity

In South China, the temperatures and humidity levels tend to be high, so it is especially important to strictly regulate the temperature and humidity of the production workshop. There are certain requirements that must be met by Grepow’s batteries, and these vary depending on the requirements of each cell and design. Some examples include performing under extremely high or low temperatures or fast charging.

Air conditioners and dehumidifiers must also be set in the factories.  These machines run for a longer period of time particularly when the electrodes are baked so as to remove any excess moisture.  Low-power industrial dehumidifiers are used during the liquid injection process.

Moreover, our factories are equipped with large-scale industrial dehumidifiers manufactured in Switzerland. Each workshop is thoroughly sealed, and the temperature and humidity are centrally controlled. The cost of only one floor of the workshop is 10 times that of an ordinaryLiPo batteryproduction workshop.

Coating machine

GrepowLiPo batteries must have strong endurance and uniform capacity. This depends on the material coating on both sides of the cathodes and anodes being uniform.

Battery Cell Stacking Process Coating machine

Roller

In order to further ensure the consistency of battery life and capacity, it is necessary to further increase the energy density of the cathodes and anodes.

Two pairs of large rollers weigh 12 tons. Under the control of the computer, the gap between the two wheels can be adjusted at any time. The thickness error of the extruded film is 0.0001 mm, ensuring that each battery has the same high capacity density.

After Grepow batteries are produced, they must not only undergo high-temperature aging but also withstand 95% relative humidity at high temperatures. Our engineers also carry out multiple safety tests before packing items for shipment.

Multifunctional Lithium Battery Testing

  With the increasing applications of lithium-ion batteries in drones, electric vehicles (EV), and solar energy storage, battery manufacturers are using modern technology and chemical composition to push the limits of battery testing and manufacturing capabilities.

Nowadays, every battery, regardless of its size, performance, and life, is determined in the manufacturing process, and the testing equipment is designed around specific batteries. However, since the lithium-ion battery market covers all shapes and capacities, it is difficult to create a single, integrated testing machine that can handle different capacities, currents, and physical shapes with required accuracy and precision.

As the demand for lithium-ion batteries becomes more diversified, we urgently need high-performing and flexible testing solutions to maximize the pros and cons and achieve cost-effectiveness.

The complexity of a lithium-ion battery

Today, lithium-ion batteries come in a variety of sizes, voltages, and applications that were originally not available when the technology was first put on the market. Lithium-ion batteries were originally designed for relatively small devices, such as notebook computers, cell phones, and other portable electronic devices.

Now, they’re a lot bigger in size for such devices as electric cars and solar battery storage. This means that a larger series, the parallel battery pack has a higher voltage, larger capacity, and larger physical volume. Some electric vehicles can have up to 100 pieces of cells in series and more than 50 in parallel.

A typical rechargeable lithium battery pack in an ordinary notebook computer consists of multiple batteries in series. However, due to the larger size of the battery pack, the testing becomes more complicated, which may affect the overall performance.

In order to achieve the best performance of the entire battery pack, each battery must be almost the same as its adjacent cells. Batteries will affect each other: if one of the batteries in a series has a low capacity, the other batteries in the battery pack will be below the optimal state. Their capacity will be degraded by the battery monitoring and rebalancing system to match the battery with the lowest performance.

The charge-discharge cycle further illustrates how a single battery can degrade the performance of the entire battery pack. The battery with the lowest capacity in the battery pack will reduce its charging state at the fastest speed, resulting in an unsafe voltage level and causing the entire battery pack to be unable to discharge again.

Battery Pack

When a battery pack is charged, the battery with the lowest capacity will be fully charged first, and the remaining batteries will not be charged further. In electric vehicles, this will result in a reduction in the effective overall available capacity, thereby reducing the vehicle’s range. In addition, the degradation of a low-capacity battery is accelerated because it reaches an excessively high voltage at the end of its charge and discharge before the safety measures take effect.

No matter the device, the more batteries in a battery pack that is stacked in series and in parallel, the more serious the problem.

The obvious solution is to ensure that each battery is manufactured exactly the same and to keep the same batteries in the same battery pack. However, due to the inherent manufacturing process of battery impedance and capacity, testing has become critical–not only to exclude defective parts but also to distinguish which batteries are the same and which battery packs to put in.

In addition, the charging and discharging curve of the battery in the manufacturing process has a great impact on its characteristics and is constantly changing.

Modern lithium-ion batteries bring new testing challenges

Battery testing is not a new thing, but, since its advent, lithium-ion batteries have brought new pressure to the accuracy of testing equipment, production capacity, and circuit board density.

Lithium-ion batteries are unique because of their extremely dense energy storage capacity, which may cause fires and explosions if they are improperly charged and discharged. In the manufacturing and testing process, this kind of energy storage technology requires very high accuracy, which is further aggravated by many new applications. The wide range of lithium-ion batteries that are available affects the testing equipment as they need to ensure that the correct charge and discharge curve is followed accurately in order to achieve the maximum storage capacity and reliability and quality.

Since there is no one size suitable for all batteries, choosing suitable test equipment and different manufacturers for different lithium-ion batteries will increase the test cost.

In addition, continuous industrial innovations mean that the constantly changing charge-discharge curve is further optimized, making the battery tester an important development tool for new battery technology. Regardless of the chemical and mechanical properties of lithium-ion batteries, there are countless charging and discharging methods in their manufacturing process, which pushes battery manufacturers to expect more unique test functions out of battery testers.

Accuracy is obviously a necessary capability. It not only refers to the ability to keep high current control accuracy at a very low level but also includes the ability to switch very quickly between charging and discharging modes and between different current levels. These requirements are not only driven by the need to mass-produce lithium-ion batteries with consistent characteristics and quality but also by the hope to use testing procedures and equipment as innovative tools to create a competitive advantage in the market.

Pouch Cell Battery and Other types of battery cell

Although a variety of tests are required for different types of batteries, today’s testers are optimized for specific battery sizes. For example, if you are testing a large battery, a larger current is required, which translates to larger inductance, thicker wires, etc. So many aspects are involved when creating a tester that can handle high currents.

However, many factories do not only produce one type of battery. They may produce a complete set of large batteries for a customer while meeting all the test requirements for these batteries, or they may produce a set of smaller batteries with a smaller current for a smartphone customer.

This is the reason for the rising cost of testing–the battery tester is optimized for the current. Testers that can handle higher currents are generally larger and more expensive because they not only require larger silicon wafers but also magnetic components and wiring to meet electromigration rules and minimize voltage drops in the system. The factory needs to prepare a variety of testing equipment at any time to meet the production and inspection of various types of batteries. Due to the different types of batteries produced by the factory at different times, some testers may be incompatible with specific batteries and may be left unused.

Whether it is for today’s emerging factories for mass production of ordinary lithium-ion batteries or for battery manufacturers who want to use the testing process to create novel battery products, flexible test equipment must be used to adapt to a wider range of batteries’ capacity and physical size, thereby reducing capital investment and improving the return on investment.

The maximum investment in lithium-ion battery testing equipment

There will always be a need for unique battery test scenarios, which require equally unique solutions. However, for many types of lithium batteries, whether they be small smartphone batteries or a large battery pack for an electric car, there can be cost-effective testing equipment.

GREPOW‘s modular battery tester solves the problems of high accuracy, high current, and flexibility of lithium-ion battery testing equipment. The company covers a variety of available battery shapes, sizes, and capacities and can cope with emerging applications, such as large battery packs and small-sized batteries commonly found in consumer electronics products, like smart bracelets.

Battery Pack

The reference design for lithium-ion battery testing enables companies to invest in lower current battery testing equipment and use them in parallel, thus eliminating the need for expensive investments in multiple machines with different current levels. The ability to use testing equipment in a variety of current ranges can optimize the investment in the machinery, thereby reducing the total costs and allowing for adaptability to the changing needs of lithium-ion battery testing.

3 types of low-temperature lithium batteries that you need to know

 

Low temperature lithium battery

Low-temperature lithium-ion batteries mainly include low-temperature lithium-ion polymer (LiPo) batteries, low-temperature 18650 batteries, and low-temperature lithium iron phosphate (LiPO4) batteries.  We will explore the advantages and disadvantages of each one.


Low-temperature lithium polymer batteries


Low-temperature LiPo batteries have the best low-temperature performance especially in smart wearable devices, where the advantages are more prominent.

Performance characteristics

Grepow’s LiPo batteries can be made to operate in environments with low-temperatures of -50℃ to 50℃. Under low-temperatures, the batteries can achieve a lower internal resistance and, thus, a high discharge rate. Compared with traditional lithium polymer batteries, Grepow’s batteries have broken through the discharge temperature limits of -20℃ to 60℃.

They are able to discharge over 60% efficiency at 0.2C at -40℃ and discharge over 80% efficiency at 0.2C at -30℃. When charged at 20℃ to 30℃ by 0.2C, the capacity can maintain above 85% after 300 cycles. The batteries can be ready for mass production, and they have been widely used in cold climates and military products.

Grepow low-temperature lithium polymer battery discharge curve

Shape advantage

With stacking technology, battery shapes can be widely customized, which allows for more flexibility and space within products. We can also create small and ultra-thin batteries with low-temperature characteristics used in special fields or professional smart equipment.

shaped batteries

Weight advantage

Under the same voltage and capacity conditions, low-temperature lithium-ion polymer batteries and low-temperature lithium iron phosphate batteries are lighter than low-temperature 18650 batteries. However, LiPo batteries are the most expensive in terms of production and manufacturing costs, which is one of the important factors limiting its use in some application areas.

Low-temperature 18650 lithium-ion batteries

Low-temperature 18650 lithium-ion batteries mainly consist of liquid electrolytes. these cylindrical batteries with steel shells have fixed dimensions, which means that their shape and size are fixed as well. The largest capacity is currently 3300mAh, which can only be achieved by a limited number of manufacturers.

Low-temperature 18650 lithium-ion batteries

Characteristics

At temperatures between -40℃ to 60℃, the effective discharge capacity is 40% to 55%, and the effective cycle life is more than 180 cycles.  At temperatures between -30℃ to 65℃ at 0.2C discharge, the effective discharge capacity is above 65%. At 1C rate discharge, the discharge capacity is above 60%, and the cycle life comes out to more than 200 cycles.

At temperatures between -20℃ to 75℃, the effective discharge capacity is more than 80%, and the cycle life is more than 300 cycles.

Due to the fixed performance and size of the battery, there is limited use for this battery, but its production and manufacturing costs are relatively low.

Low-temperature lithium iron phosphate batteries

Low-temperature LiPO4 batteries have two kinds of packaging cases: one is a steel case, which is currently mostly used in new energy batteries, such as energy-storage batteries and new energy vehicle batteries; the other is a soft-pack LiPO4 battery with aluminum plastic film for the outer packaging.

The performance of this battery is basically the same as that of the LiPo battery. However, the low-temperature performance of LiPo batteries is better than that of 18650 batteries. The development of LiPO4-battery technology has not been long, and the requirements for production equipment are relatively high.

The charging voltage of 3.7V lithium battery

 

3.7V lithium battery

The 3.7v lithium battery is a lithium battery with a nominal voltage of 3.7v and a full-charge voltage of 4.2v. Its capacity ranges from several hundred to several thousand mAh. It is generally used in various instruments and meters, testing instruments, medical instruments, POS machines, notebook computers, and other products.

About the capacity of 3.7V lithium battery capacity, the larger the volume of a single lithium battery, the greater the capacity, or we can say that the more the number of lithium batteries in parallel, the greater the capacity.

Generally, a 3.7v lithium battery needs a “protection board” for over-charging&discharging. The battery without a protection board can only be charged with 4.2V voltage, because the ideal full charge voltage of a lithium battery is 4.2v, once the voltage exceeds 4.2v, the battery may be damaged. Charging in this way requires someone to monitor the condition of the battery at all times.

On the contrary, the battery with a protection board can be charged with 5V (range from 4.8V to 5.2V). As we know, in most cases, a 5V charger can be used for USB of computers and mobile phones.

The charging cut-off voltage of 3.7V battery is 4.2V and the discharge cut-off voltage is 3.0V.  Therefore, when the open-circuit voltage of the battery is lower than 3.6V, it should be able to charge. It is better to use the 4.2V constant voltage charging mode, so you don’t need to pay attention to the charging time. If 5V charging is used, overcharging is easy to happen.

1. Floating Charge

Floating charging means that the device is being charged while being used. This method is often used in standby power supply situations. When the voltage is lower than 12V, the equipment can not be charged. At the same time, if the voltage is too high, the circuit will be affected. Therefore, the voltage of the floating charge is 13.8V.

2. Cycle Charging

Cycle charging refers to the full charge to restore the capacity of the battery. When the battery is fully charged, it is measured without disconnecting the charger. At this time, the voltage is generally around 14.5V, and the maximum voltage will not exceed 14.9V. After disconnecting the charger for 24 hours, the voltage will generally be around 13V to 13.5V. After one week, it will be dropped to 12.8v ~ 12.9v. The specific voltage value of different batteries is different.

The nominal voltage of lithium battery is 3.7V and the charging voltage is 4.2V. The nominal voltage of batteries in series is only 7.4v, 11.1v, 14.8V…  which corresponds to the charging voltage (i.e. charger no-load output voltage) of 8.4v, 12.6V, 16.8v…It is impossible to be a multiple of 12V.

The output voltage of the charger is generally 5V, even 4.9v does not meet the standard. If you use a 4.9v charger to directly charge the pool, it is definitely not allowed. However, there will be a control circuit inside the mobile phone or the seat charger. Unless the circuit goes wrong, it will limit the charging voltage to be within the allowable range, so there is no need to worry about this.

Best Custom Medical Battery Solution for Top Medical Device Companies

 Advanced lithium battery technology delivers unparalleled efficiency and convenience for everything from smartphones to portable medical devices. The advantages are significant. Using a lithium battery can reduce the weight of the device and extend the working time between charges, making it more useful for providing medical care.

Medical Grade Lithium Batteries As you might expect, the safe integration of lithium batteries into the design is not only a major issue but also a challenge for medical device developers. Fortunately, many regulatory agencies such as UL, IEC, and FDA provide certification to regulate the safety of medical devices and the lithium batteries that power them. All certificates focus on the end user's security protection of the medical device in the target operating environment.

Medical device providers must comply with safety certificate guidelines

GREPOW believes that every medical device provider must comply with the safety certificate guidelines to provide users with safety and comfort. This is a problem because the current limited understanding of lithium battery technology and the risk of liability for lithium battery technology may pose greater risks to related equipment. Medical device developers need to fully understand and adopt the characteristics of lithium batteries in product design to minimize risk and exposure.

For example, developers who must use rectangular lithium polymer batteries to install into their medical devices may experience the inconsistent performance, expansion rates, and reliability issues after the use of Li-Po batteries. We have the knowledge of designing batteries to maintain good performance under these adverse conditions. The expansion rate and reliability issues after use. We have the knowledge of designing batteries to maintain good performance under these adverse conditions. The expansion rate and reliability issues after use. We have the knowledge of designing batteries to maintain good performance under these adverse conditions.

certifications

Medical device manufacturers should purchase certified lithium batteries

Medical grade batteries In order to comply with all medical certificates, lithium batteries must be produced by UL-certified factories. From chemical production to battery assembly and final testing, lithium battery production must be performed in a UL certified facility.

Any medical device manufacturer should not purchase lithium batteries from a factory that is not UL listed because they will not receive FDA approval. Therefore, in order to serve our customers, GREPOW has taken all necessary steps to obtain UL certification for our manufacturing plants.

In order to obtain FDA approval, there is a high demand for documentation on testing, safety and quality standards, and performance for UL certified plants. UL, IEC, and FDA have extensive documentation requirements to ensure the safe production of medical devices and to operate safely in medical environments.

Regulators may not know exactly what the medical device does. However, they do understand the materials involved and provide guidelines to medical device manufacturers to produce their products in a manner that prevents failures that could result in personal injury or death. The goal is to ensure that no accidents occur.

If an error occurs, these guidelines can also help the OEM and its supply chain track the root cause to prevent the error from occurring again. In order to properly track responsibilities, these regulators require complete documentation from equipment manufacturers and lithium battery manufacturers.

  • Medical equipment on fire: The mechanical design of the GREPOW medical battery allows the shape of the battery pack to be changed to prevent explosions, which can cause debris and damage.
  • The battery BMS is designed to be redundant and meets all hypothetical safety issues for UL inspectors.
  • Pass the high-temperature aging test, low-temperature aging test
  • Batch processing test with long batch processing
  • Drop and impact test
  • The physical destructive penetration test

These tests were conducted to evaluate the design of the GREPOW medical battery to understand how the GREPOW medical battery performs in protecting users in the event of any form of damage or environmental disaster. We can say with certainty that our battery design has passed these tests before it is produced.

Medical battery production at UL-certified factories

In order to comply with all medical certificates, lithium batteries must be produced by a UL-certified factory. From chemical production to battery pack assembly and final testing, lithium batteries must be produced in UL-certified plants. In the process of applying for FDA approval, the requirements for testing, safety and quality standards, and performance documentation for UL certified plants are high. Any medical device manufacturer should not purchase lithium batteries from a factory that is not UL listed because they will not receive FDA approval.
