Electrolyte

Electrolyte: A liquid that can conduct electricity, usually composed of a dissolved electrolyte (such as salt, acid, or base) and a solvent (usually water); It is the main medium for lithium ions to move between the cathode and anode in lithium batteries, and provides the necessary environment for electrochemical reactions inside the battery.
