3.7V 5441113 3000mah Li Polymer Battery for Portable Devices with Steady Performance
Product Description
Lithium polymer battery widely know as li-po battery or li-polimer battery, is a member of the lithium battery family. But this kind of lithium battery has it's unique advantages that other cylindrical lithium battery do not have, such as high energy density, miniaturization, ultra-thin size, super lightweight and high safety. Due to these advantages, lithium polymer batteries can be made into whatever shape and capacity to suit the requirements of various products. Besides, it uses aluminum-plastic as the outer, so the internal problems can be immediately displayed through the outer packaging, even if a security risk occur, it will not explode or fire, only bulge.
The electrolyte of the polimer battery plays a dual and important function of the diaphragm and the electrolyte: on the one hand, like a diaphragm it separates the positive and negative electrode materials, that makes the battery has no self-discharge and short circuit problem inside; on the other hand, it conducts lithium ions between the positive and negative electrodes like an electrolyte. The polymer electrolyte not only has good electrical conductivity, but also has the characteristics of good elasticity, light weight, easy film formation and so on, which also conforms to the development trend of chemical power supply and environmental protection. That why the li-polimer battery is also more environmental friendly.
This 5441113 battery is with very thin thickness that only 5.4mm, which is very suitable for the laptop devices and other product which requires thin thickness.
