Lithium polymer (LiPo) batteries are a type of rechargeable battery that uses a polymer electrolyte instead of a liquid one. This design allows for a lighter and more flexible battery, making them popular in applications like remote-controlled devices, drones, and smartphones. They can be made in various shapes and sizes, which provides versatility in design. LiPo batteries have a high energy density, meaning they can store a lot of energy relative to their weight. However, they require careful handling and charging to prevent issues like swelling or fire. Proper management systems are essential for safe use in devices like electric vehicles and portable electronics.
