Abstract
A cell includes a case designed to form a housing, an assembly of stacked electrodes placed inside the housing and including one or more units each having a positive electrode, a negative electrode, a separator between the positive and negative electrodes and an electrolyte. The assembly is held together, and at least each negative electrode of the one or more units includes one or more notches, vertically aligned along the height of the assembly so to design a substantially flat contact surface.
Claims15
A cell comprising:
- a case designed to form a housing;
- an assembly of stacked electrodes placed inside the housing and including one or more units each having a positive electrode, a negative electrode, a separator between the positive and negative electrodes and an electrolyte, wherein the positive electrodes of the one or more units are electrically connected together to form a positive terminal and the negative electrode of the one or more units are electrically connected together to form a negative terminal;
- and
- one or more clamps having a flat side surface and only one of a top surface and a bottom surface for holding together the assembly,
- wherein at least each negative electrode of the one or more units comprises one or more notches, vertically aligned along the height of the assembly so to provide a substantially flat contact surface, said notches being arranged at a distance from the positive terminal and from the negative terminal,
- wherein the only one of a top surface and a bottom surface projects along a top surface of the assembly or a bottom surface of the assembly respectively, and
- wherein each of the one or more clamps is in contact with a respective one of the one or more notches such that the flat side surface of each of the one or more clamps extends along the flat contact surface of the respective one of the one or more notches.
