Li-PO Cells is an abbreviation for lithium-ion polymer batteries, which are rechargeable batteries that use polymer electrolytes instead of liquid electrolytes for lithium-ion technology. This polymer electrolyte is in a semi solid state and has high conductivity, which can provide higher specific energy for the battery, resulting in miniaturization, ultra-thinning, lightweight, and higher safety. Lithium polymer batteries can be made into batteries of any shape and capacity to meet the needs of various products. Li-PO batteries are typically composed of several identical cells to increase discharge current, or multiple battery packs connected in series to increase available voltage.

Electrochemistry: Li-PO Cells are composed of the following parts: Positive electrode: LiCoO2 or LiMn2O4; Electrolyte separator: Conductive electrolyte polymer (such as polyethylene glycol, PEO); Negative electrode: carbon and carbon materials. Positive: Li-ions are embedded during discharge and detached during charging. • Charging: LiCoO2 → Li1-x CoO2 + xLi+ + xe− • Discharge: Li1-x CoO2 + xLi+ + xe− → Li CoO2 Negative: Li-ion detachment during discharge and insertion during charging. • Charging: xLi+ + xe− + 6C → LixC6 • Discharge: LixC6 → xLi+ + xe− + 6C

Advantages: • Good safety performance • Thin thickness • Lightweight • Customizable shape • Large capacity • Low internal resistance • High charging and discharging power • No memory effect • Long service life • Simple series parallel combination • Wide range of use

Applications: • Personal Electronics: mobile devices, power banks, very thin laptop computers, portable media players, wireless controllers for video game consoles, wireless PC peripherals, electronic cigarettes, and other applications where small form factors are sought •Drones, Radio-controlled Equipment and Aircraft • Uninterruptible Power Supply Systems • Electric Vehicles: electric and hybrid vehicles • Engine Start Battery
