ELECTROLYTE SUPPLY SYSTEM AND SECONDARY BATTERY USING SAME

An electrolyte supply system for supplying an electrolyte to a use point, includes: a receiving storage tank configured to store the electrolyte that has been delivered; a supply storage tank to which the electrolyte is transferred from the receiving storage tank; a temperature control device configured to control temperatures of the electrolyte in the receiving storage tank and that in the supply storage tank; and a supply pipe that is laid from the supply storage tank to the use point. The electrolyte supply system is highly safe because the storage tanks are disposed in an outdoor location, and furthermore, performs a temperature control process for the receiving storage tank before the electrolyte is transferred to the supply storage tank. Thus, it can supply the electrolyte to the use point 24 hours a day even with little temperature control in the supply storage tank.
