Lithium-ion polymer batteries (often abbreviated to LiPo, Li-poly, lithium-poly and LIP) belong to the Li-ion family. They have a low self-discharge rate, are long-lasting and have a high capacity. Compared to other Li-ion batteries, the energy capacity of lithium polymer batteries is slightly lower, but they are more resistant to overcharging. The polymer-based electrolytes enable these lightweight batteries to be manufactured in a wide range of designs and shapes, making them very versatile. LiPo batteries are often use in battery electric vehicles, remote-controlled electric models, smartphones and notebook computers.
