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 devices like smartphones, drones, and remote-controlled vehicles. LiPo batteries can be made in various shapes and sizes, which helps manufacturers create slim and compact products. One of the key advantages of lithium-polymer batteries is their 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 overheating. Proper management ensures safety and longevity in devices that utilize LiPo technology.
