The mode of operation of LiPo batteries is identical to that of lithium-ion batteries. Therefore, the same statements apply to lithium-polymer batteries as to lithium-ion batteries. The advantage is the almost infinite number of sizes due to the absence of a stable steel housing. Instead of a solid housing, a plastic-coated aluminum foil is used. This means that very thin battery designs can be realized.
Lithium polymer cells are therefore also lighter. In addition, the large number of different sizes leads to great design freedom for the end application. Individual dimensions are possible in relatively small quantities, so that the space available for the battery can be optimally utilized. The disadvantage is that the battery is more sensitive to mechanical influences due to the lack of a fixed housing.
In addition, the lithium polymer cells react critically to overcharging. LiPo batteries are therefore equipped with protective electronics that protect this rechargeable battery from overcharging. When charging, only chargers for this battery chemistry should be used. LiPo batteries are also known as soft/pouch cells.
