The self-discharge of lithium-ion batteries is a concern that needs attention. It is mainly caused by internal chemical reactions and physical processes, such as extreme electric-consuming reactions and impurities in materials. Testing methods like resting test and cycling test can be used to evaluate the level of self-discharge.

Polymer batteries are high quality and affordable lithium batteries that are used in a wide range of industries. However, at the end of their life, they need to be disposed of as non-recyclable waste, rather than being punctured and thrown away. Piercing a battery and throwing it away is a very unsafe practice. Why is it unsafe to puncture a polymer battery and throw it away?

This article describes the principles that make lithium polymer batteries susceptible to fire and the factors that can lead to safety problems during the manufacturing process. It also covers the testing standards and methods for the safety performance of lithium batteries. By understanding these issues and testing methods, one can better ensure the safety performance of lithium batteries.

Lithium polymer batteries are widely used in a variety of fields because of their high energy density, lightweight, and environmentally friendly properties. However, the temperature can affect the performance of these batteries and reduce their discharge performance.

There are many types of batteries, among which polymer batteries are favored by consumers, so what are the advantages of polymer batteries?

On June 9th, the China Automotive Power Battery Industry Innovation Alliance (referred to as the "Battery Alliance") released the TOP15 ranking of domestic power batteries for May 2023 and January-May.

Battery protection board is designed to protect the battery, so many batteries have protection board. But many people don’t understand the function of battery protection board. I will introduce the function of battery protection board to the reader.
