Lithium Polymer Battery
3.7V 210mAh bluetooth earphone Lipo batteries 203040
A lithium-ion polymer (LiPo) battery (also known as Li-poly, lithium-poly, PLiON, and other names) is a rechargeable Li-ion battery with a polymer electrolyte in the liquid electrolyte used in conventional Li-ion batteries. There are a variety of LiPo chemistries available. All use a high conductivity gel polymer as the electrolyte. LiPos provide higher specific energies than other lithium batteries, often used in systems where weight is an important factor, such as mobile devices, drones, and some electric vehicles. This FAQ begins with a high-level comparison of Li-ion and LiPo batteries, followed by a detailed look at the six basic lithium battery chemistries most suitable for use in LiPo batteries. It closes with a look into the future and the possible development of aluminum-air polymer batteries and solid-state batteries.
