Abstract: A metal foil including on at least one of its sides a layer of a material including: a metal or a metal alloy, carbon, hydrogen, and optionally oxygen, the atomic percentage of the metal or of the metals of the alloy in the material ranging from 10 to 60%, the atomic percentage of carbon in the material ranging from 35 to 70%, the atomic percentage of hydrogen in the material ranging from 2 to 20%, and the atomic percentage of oxygen if present in the material being less than or equal to 10%. The metal foil can be used in the manufacture of a cathode of a lithium-ion electrochemical cell. The deposition of this layer reduces the internal resistance of the cell.

Abstract: A device for aiding in the fracture of a vent of an electrochemical cell includes a main body having a first surface and a plurality of lobes extending out from the first surface of the main body such that an open space is provided between adjacent lobes. Each of the plurality of lobes are configured to make contact with the vent during deployment of the vent such that the vent completely separates from a bottom of the electrochemical cell. The open space provided between adjacent lobes is configured to allow gases from inside the electrochemical cell to pass through during deployment of the vent.

Abstract: In a system and method for detecting venting of a sealed storage cell, the sealed storage cell comprises a container with a sealing cap adapted to be detached from the container and move in the presence of gas overpressure inside the container to allow venting of the storage cell. The detection system comprises a printed circuit board with a central portion designed to be situated opposite the sealing cap, a peripheral portion surrounding the central portion and connected to the central portion by a hinge adapted to flex during movement of the sealing cap, and at least one frangible portion adapted to break upon movement of the sealing cap. An electrical printed track connects the peripheral portion to the central portion through the hinge and frangible portion(s), and is designed to be broken upon breaking of the frangible portion(s) following movement of the sealing cap.
