Lithium-ion polymer batteries (often abbreviated as LiPo, Li-poly, lithium-poly, and LIP) belong to the Li-ion family. They have a low self-discharge rate, are durable, and have high capacity. Compared to other Li-ion batteries, lithium-polymer batteries have slightly lower energy capacity but are more resistant to overcharging. Polymer-based electrolytes allow these lightweight batteries to be manufactured in various designs and shapes, making them very versatile. LiPo batteries are often used in battery-powered electric vehicles, remote-controlled electric models, smartphones, and notebook computers.
