Lithium polymer battery is an important part of lithium polymer battery. The composition of lithium polymer rechargeable battery is as follows: battery + protection circuit board, lithium polymer battery is generally used in digital products or In general power tools, there are many grades of lithium polymer battery cells. How are the lithium polymer battery cells graded and what is the difference between the cell grades? Let me give you a brief introduction to lithium polymer cells. What is the difference between the battery cell grades, I hope to help everyone.

1. What are the grades of lithium polymer battery cells?

    Lithium polymer battery cells (http://www.xl-battery.com/) are classified into: Class A lithium polymer battery cells, Class B lithium polymer battery cells, and Class C lithium polymer battery cells .

2. What is a Class A lithium polymer battery cell?

    A-class battery cells are those whose capacity, size, internal resistance and other parameters meet the company‘s technical parameters and have excellent performance without abnormality. They can be called A-class lithium polymer battery cells.

3. What are B-class and C-class lithium polymer battery cells

    Class B cells refer to the fact that in the process of producing cells in the factory, there are slight defects in voltage, capacity, size, appearance, etc., but the performance is excellent. Some of the parameters of the cells fail to reach Class A cells. Standard, we generally define it as B-class battery.

    C-class batteries refer to the eliminated batteries. C-class batteries are out of the standard parameters of A-class batteries in terms of voltage, capacity, size, internal resistance, appearance, etc., and there are some problems in the performance of defective batteries. Generally defined as C-class cells.

Fourth, which is the best lithium polymer battery manufacturer

    Dongguan Xuanli Electronics Co., Ltd. was established in 2009, English abbreviation xuanlibattery, specializing in the manufacture and development of laminated soft-pack lithium polymer batteries. So far, it has become a well-known laminated battery manufacturer at home and abroad. Spin force lithium batteries are widely used in drones, RC models, agricultural plant protection, sports cars, auto parts, medical, outdoor, maritime, military, industrial, wearable Devices, AR/VR, and consumer electronics.

Spin force is a world-renowned provider of integrated customization solutions for lithium polymer batteries. It can not only provide customers with single customization services such as bare cells, battery structures, BMS, etc., but also meet customer battery integration (cell + BMS + structure). ) custom requirements.

Spin force‘s polymer battery customization solutions mainly include the following three types:

    (1) Physical customization of lithium polymer bare cells: cell thickness, cell width, cell length, cell shape, cell strength, battery capacity.

(2) Chemical customization of lithium polymer bare cells: charge and discharge temperature, charge and discharge current (including instantaneous discharge), discharge rate, voltage, cell internal resistance, and cycle life.

   (3) Combination of software and hardware, communication management.
