Process of charging an electrochemical generator having zinc negative electrodes and an electrochemical generator for putting the process into practice
First Claim
1. Process for charging a reversible electrochemical generator including of a plurality of cells which are electrically in series, each of said cells comprising a zinc negative electrode and a positive electrode between which circulates a basic electrolyte containing solubilized zinc, said process comprising the steps of:
- causing the electrolyte in the cells to circulate successively from one cell to the next, applying to said electrodes a charging current forming a succession of approximately rectangular charging pulses, and periodically reversing the direction of circulation of the electrolyte during said charging step.

Abstract
This invention relates to a process for charging a reversible electrochemical generator consisting of a plurality of cells, which are electrically in series, comprising a zinc negative electrode and a positive electrode between which a basic electrolyte, containing solubilized zinc, circulates, consisting in making the electrolyte in the cells circulate successively from one cell to the next and in applying to it a charging current forming a succession of approximately rectangular pulses. The direction of circulation of the electrolyte during charging is periodically reversed.
