Differences of Cylindrical Li ion and Li Polymer battery?
1. Packing material: 1) Cylindrical lithium-ion battery: steel and aluminum shell 2) Lithium polymer battery: aluminum plastic film
2. Shape: 1) Cylindrical lithium ion battery: cylindrical 2)Lithium polymer battery: square, theoretically shape is arbitrary, according to customer requirements for different sizes, especially for portable devices applications.
3. Electrolyte: 1) Cylindrical lithium ion battery: liquid electrolyte 2) Lithium polymer battery: gel electrolyte or dry electrolyte
