Metal-halogen secondary battery system
First Claim
1. A metal-halogen secondary battery system comprising:
- a positive plate electrolyte circulating line including a positive plate electrolyte tank and a first pump for circulating a positive plate electrolyte into at least one positive plate galvanic reaction chamber;
a negative plate electrolyte circulating line including a negative plate electrolyte tank and a second pump for circulating a negative plate electrolyte into at least one negative plate galvanic reaction chamber;
an electrolyte discharge pipe line connected to each of said positive and negative plate galvanic reaction chambers through a discharging on-off valve so as to discharge said positive and negative plate electrolytes in said positive and negative plate galvanic reaction chambers to the outside of said electrolyte circulating lines;
a positive plate galvanic reaction chamber cleaning line established by connecting, in place of said positive plate electrolyte tank, a positive plate galvanic reaction chamber cleaning solution tank to said positive plate galvanic reaction chamber through said first pump and first change-over on-off valve means;
a negative plate galvanic reaction chamber cleaning line established by connecting, in place of said negative plate electrolyte tank, a negative plate galvanic reaction chamber cleaning solution tank to said negative plate galvanic reaction chamber through said second pump and second change-over on-off valve means;
a deionized water circulating line established by connecting a deionized water tank to said cleaning line through connecting on-off valves so as to circulate deionized water instead of said cleaning solutions through said cleaning lines; and
a cleaning solution discharge pipe line connected to said cleaning line through a third discharging on-off valve so as to discharge said cleaning solutions or said deionized water existing in said cleaning lines to the outside thereof.

Abstract
A metal-halogen secondary battery system having electrolyte circulating lines for its positive and negative plate galvanic reaction chambers, further incorporates in the electrolyte circulating lines cleaning lines and a deionized line circulating line including a positive plate galvanic reaction chamber cleaning solution tank, a negative plate galvanic reaction chamber cleaning solution tank, a deionized water tank, a cleaning solution discharge pipe and a plurality of pipes and on-off valves for connecting and opening and closing the tanks and the discharge pipe, thereby making circulation cleaning of the reaction chambers possible and ensuring restoration of the battery characteristics and longer battery life.
