A battery or an accumulator including an anode case, an anode situated inside the anode case, a cathode case joined to the anode case, a seal sealing the cathode case to the anode case, a cathode situated inside the cathode case between the anode and the cathode case, and a membrane between the anode and the cathode. An outer surface of the battery includes at least one marking.

Battery with a non-conductive structured surface

The present invention concerns a battery including an anode case, an anode situated inside the anode case, a cathode case fixed to the anode case, a seal sealing the cathode case to the anode case, a cathode situated inside the cathode case between the anode and the cathode case, and a membrane between the anode and the cathode, said battery being characterized in that one outer surface of said accumulator includes at least one marking created by local heating of material, said marking being electrically conductive.
