Rechargeable 400mAh Lithium Polimer Battery 3.7V 602040 for Portable Devices
Product Description
Li-polymer battery (Li-polymer, also known as polymer lithium-ion battery), has a variety of advantages such as high energy, miniaturization, ultra-thin, lightweight and high safety. Based on such advantages, lithium polymer batteries can be made into batteries of any shape and capacity to meet the needs of various products. And it uses aluminum-plastic packaging, internal problems can be immediately displayed through the outer packaging, even if there is a security risk, it will not explode, only bulge.
In polymer batteries, the electrolyte plays a dual function of the diaphragm and the electrolyte: on the one hand, like a diaphragm, it separates the positive and negative electrode materials, so that there is no self-discharge and short circuit inside the battery, and on the other hand, it conducts lithium ions between the positive and negative electrodes like an electrolyte.
Polymer electrolyte not only has good electrical conductivity, but also has the characteristics of light weight, good elasticity, easy film formation and so on, which also conforms to the development trend of chemical power supply with light weight, safety, high efficiency and environmental protection.
