Classification of electrolytes for lithium ion batteries

Electrolyte plays the role of transferring charge between the positive and negative electrodes. It should be conductive to ions and insulated from electrons. It has a very important impact on battery cycle performance, operating temperature range and battery durability. For lithium ion batteries, the composition of electrolyte involves at least two aspects: solvent and lithium salt.

A. Liquid electrolyte

B. Solid electrolyte
