Abstract
The invention relates to a rechargeable electrochemical system suitable for use in an electric vehicle. It comprises a battery comprising at least one positive electrode depolarized by air, at least one negative collector, a tank, an electrolyzer comprising at least one positive electrode and one negative electrode, an electrolyte bearing in suspension the negative active material. The electrolyte is caused to flow either between the tank and the battery or between the electrolyzer and the tank, wherein the total volume of the alkaline electrolyte, bearing in suspension a negative active material containing 250 g to 350 g per liter of equivalent zinc, lies between one and a half and three times the internal volume of the electrolyzer.
