3.7v 55mah li polymer battery Manufacturers

1. The 18650 battery is cylindrical with transparent liquid inside. This is due to the battery concept and material. 18650 is suitable for high current, so that almost all laptops and electric cars are basically designed with 18650 batteries; only super notebooks, This is due to environmental protection and energy saving, so polymer lithium-ion batteries can be used instead of 18650 batteries, especially for tablet computers, etc. Digital cameras are due to the large voltage and instantaneous high current required for charging and discharging of the photo flash, so only 18650 can be used. Similar batteries, only slightly smaller;

In recent years, with the explosion of TWS earphones, new rechargeable button batteries with advantages such as high endurance, high security and personalization have been unprecedentedly popular in various small wearable devices such as TWS earphones, smart watches, smart glasses and smart speakers.

Polymer lithium battery is a kind of lithium battery family. It also has other nicknames such as soft-pack lithium battery, soft-pack high-rate battery, polymer lithium-ion battery, soft-pack ternary lithium battery, etc., which makes many friends feel a little confused. Below we mainly introduce what polymer lithium battery is in detail from the aspects of manufacturing raw materials, charge and discharge performance, and main application fields, so that everyone can have a more comprehensive understanding of polymer lithium battery.

Over long-term use, the internal resistance of a lithium ion battery single cell inevitably increases. This increase in internal resistance is directly related to the battery's output efficiency, temperature rise, and safety performance.
