What is the main difference between polymer batteries and lithium-ion batteries?

1. The fundamental difference is the raw material, which is the total source of the different performances of the two. Polymer battery refers to the use of polymer materials in at least one of the three major components of positive electrode, negative electrode or electrolyte. Macromolecules mean large molecular weights, and the corresponding concept is small molecules. Macromolecules have high strength, high toughness and high elasticity. The polymer materials currently developed for polymer batteries are mainly used for positive electrodes and electrolytes. ①In addition to the inorganic compounds of lithium-ion batteries, the cathode materials of polymer batteries can also use conductive high-molecular polymers; ②The electrolytes of polymer batteries include polymer electrolytes (solid or colloidal) and organic electrolytes, which are used in lithium-ion batteries. Electrolyte (liquid or gel) 2. Shape difference. Polymer batteries can be thinner, arbitrarily shaped and arbitrarily shaped. The reason is that the electrolyte can be solid or colloidal rather than liquid, while lithium-ion batteries use electrolyte. , A sturdy casing is needed as a secondary package to contain the electrolyte. Therefore, this also makes lithium-ion batteries add some weight. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
