METAL-HALOGEN SECONDARY BATTERY SYSTEM

摘要

The battery system has electrolyte circulating lines for its positive and negative plate galvanic reaction chambers (2, 3), and incorporates in the electrolyte circulating lines cleaning lines and a deionized water circulating line including a positive plate galvanic reaction chamber cleaning solution tank (TA-3), a negative plate galvanic reaction chamber cleaning solution tank (TA-4), a deionized water tank (TA-5), a cleaning solution discharge pipe (8) and a plurality of pipes and on-off valves for connecting and opening and closing the tanks and the discharge pipe, thereby making possible circulation cleaning of the reaction chambers and ensuring restoration of the battery characteristics and longer battery life.
