3.7v li polymer battery 350mah Manufacturers

With the expanding market for portable electronic devices, the demand for high-performance and safe batteries is increasing. Against this backdrop, 2s LiPo (Lithium Polymer) battery packs are emerging as the focal point of the market due to their superior performance and wide range of applications. Specifically, 7.4V 2s LiPo battery packs, with their high energy density, long cycle life, and rapid charging capabilities, have garnered consumer favor.

According to the foreign media The Verge, batteries sometimes explode. Those explosion videos are scary, but scientists and startups have been working hard to build safer batteries. They are improving the battery design and testing new materials, hoping to solve the safety problem once and for all. But every method seems to have a trap, and the most practical solution at present may be the most boring. There are three strategies to improve battery: avoid using flammable liquid as solid battery; Make the battery module fireproof; Modify the existing functional characteristics of the battery slightly. At least as far as batteries are concerned, this change may come

In the past, all mobile power supplies used 18650 batteries. Because of its light weight and large capacity, 18650 batteries have won the favor of many brands. However, with the improvement of lithium polymer battery technology, manufacturers have gradually switched to lithium polymer batteries. Why do mobile power supplies begin to use lithium polymer batteries?

Is there any special reason for the use of aluminum foil and copper foil for the current collection of positive and negative electrodes? Is there any problem with using it in reverse?

Diaphragm 135 ℃ automatic shutdown protection, using internationally advanced Celgas2300PE-PP-PE three-layer composite membrane. When the temperature of the battery reaches 120 ℃, the membrane holes on both sides of the PE composite membrane are closed, the internal resistance of the battery increases, and the internal temperature of the battery slows down. When the temperature of the battery reaches 135 ℃, the PP membrane hole is closed, the battery is internally open, and the temperature of the battery is no longer increased, ensuring the safety and reliability of the battery.
