1. A method of operating a metal-halogen battery, comprising the steps of:
- carrying out an operation of discharging the battery at a constant current having a first current value throughout charging the battery; and
initiating an operation of charging the battery at a second current value higher than said first current value and continuing the charging operation at a third current value which linearly decreases from said second current value to a zero value toward a termination of charging the battery.

Abstract
A method of operating a metal-halogen battery such as a zinc-bromine battery, intended to prevent dendrite from formation on an electrode during charging the battery. The method comprises the step of carrying out an operation of discharging the battery at a predetermined constant current having a first current value throughout charging the battery; and the step of initiating an operation of charging the battery at a second current value of two times the first current value and maintaining the changing operation at a third current value which linearly decreases from the second current value to a zero value toward a termination of charging the battery.
