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.


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
