Polymer Battery
Polymer batteries are rechargeable lithium-ion batteries that use a polymer electrolyte instead of a traditional liquid electrolyte. This polymer electrolyte can be a solid or gel-like substance, allowing the batteries to be made into ultra-thin, lightweight, and flexible shapes. Compared to traditional lithium-ion batteries, polymer batteries offer greater design freedom, higher safety, and are more suitable for small electronic devices. They are widely used in consumer electronics, smart devices, medical devices, and wearable technology.
