Abstract: Battery comprising at least one anode and at least one cathode, arranged on top of one another in an alternating manner, the battery comprising lateral edges and longitudinal edges, in which the anode comprises a current collector substrate, —at least one anode layer, and—optionally, a layer of an electrolyte material, and the cathode comprises: —a current collector substrate, at least one cathode layer, and—optionally a layer of an electrolyte material such that the battery comprises successively at least one anode layer, at least one layer of an electrolyte material and at least one cathode layer, characterized in that each anode and each cathode comprises a respective main body, separated from a respective secondary body by a space that is free of any electrode, electrolyte and/or current collector substrate material, the free space joining or extending between the opposite longitudinal edges of the battery.

Abstract: An assembly of batteries includes a first battery and a second battery electrically connected in parallel. The first battery is configured to deliver a battery capacity in a first power supply voltage range. The second battery is configured to deliver a battery capacity in a second voltage range. An upper limit of the second voltage range is set between upper and lower limits of the first voltage range. In an operating system, if supplied battery power falls below a threshold, the parallel connected first and second batteries are disconnected from the load.

Abstract: An object containing electronic circuits and a rechargeable cell, wherein the cell is arranged close to a surface of the object, a charge coil being shiftable with respect to the cell between an operating position where it is arranged around the cell and a recharge position where it is axially offset with respect to the cell.

Abstract: A method for protecting a thin-layer battery, including the steps of: periodically operating the battery at a forced discharge current, which is a function of temperature; and disconnecting the battery as soon as the voltage across it reaches a threshold, said threshold being greater than its critical voltage for a maximum discharge current under a maximum temperature.

Abstract: A method for protecting a thin-layer battery connected to an intermittent load including the steps of periodically operating the battery at its maximum discharge current, and disconnecting the battery as soon as the voltage across it reaches a threshold value greater than its critical voltage for the maximum discharge current.

Abstract: A device comprising a chamber in which a hydrogen-air or methanol-air type fuel cell is arranged, the chamber including an upper wall in which an opening is formed, a lower wall on which the cell is arranged so that the surface of exposure to air of the cell faces the upper wall, and a fan arranged in the opening.
