Estimating the term…
Provided is a rechargeable battery comprising an anode, a cathode, an electrolyte disposed between the anode and the cathode, a protective housing that at least partially encloses the anode, the cathode and the electrolyte, a heat-spreader element disposed at least partially inside the protective housing and configured to receive heat from an external heat source at a desired heating temperature Th to heat up the battery to a desired temperature Tc for battery charging. Preferably, the heat-spreader element does not receive an electrical current from an external circuit (e.g. battery charger) to generate heat for resistance heating of the battery. Charging the battery at Tc enables completion of the battery in less than 15 minutes, typically less than 10 minutes, and more typically less than 5 minutes without adversely impacting the battery structure and performance.
A battery charging system comprising at least one charging circuit to charge at least one rechargeable battery cell and a heat source to provide heat that is transported through a heat spreader element, implemented fully or partially inside said at least one battery cell, to heat up said battery cell to a desired temperature Tc before or during charging of said battery cell, wherein said heat source is disposed outside said at least one battery cell.
A method of operating a battery charging system comprising multiple charging stations, said method comprising:
