Abstract
A cell that includes a pouch, a cathode including a cathode current collector disposed between two cathode active material layers, an anode including an anode current collector disposed between two anode active material layers, and separator disposed between the cathode and the anode. A first dimension in an X-axis and/or Y-axis of the separator, anode current collector and cathode current collector are the same. A method of manufacturing the cell includes continuous roll to roll lamination of cell components.
Claims20
A cell comprising:
- a pouch extending along a first axis (X-axis) to define a width, a second axis (Y-axis) orthogonal to the first axis to define a length, and a third axis (Z-axis) orthogonal to the first and second axes to define a thickness;
- a cathode comprising a cathode current collector disposed between two cathode active material layers;
- an anode comprising an anode current collector disposed between two anode active material layers;
- and
- a separator disposed between the cathode and the anode,
- wherein a first dimension in the X-axis and/or Y-axis of the separator, the anode current collector and the cathode current collector are the same.
A method of manufacturing a cell by roll-to-roll lamination comprising:
- providing a pouch extending along a first axis (X-axis) to define a width, a second axis (Y-axis) orthogonal to the first axis to define a length, and a third axis (Z-axis) orthogonal to the first and second axes to define a thickness;
- disposing a cathode current collector between two cathode active material layers to provide a cathode;
- disposing an anode current collector between two anode active material layers to provide an anode;
- disposing the separator between the cathode and the anode to form a multi-layer of the cathode, the separator, and the anode;
- performing a continuous roll to roll lamination of the multi-layer;
- and
- dimensioning a separator, the anode current collector and the cathode current collector to be the same in the X-axis and/or Y-axis.
A tape comprising:
- a body extending along a first axis (X-axis) to define a width, a second axis (Y-axis) orthogonal to the first axis to define a length, and a third axis (Z-axis) orthogonal to the first and second axes to define a thickness;
- the body further comprising:
- a first film layer;
- a second middle adhesive layer;
- and
- a third acrylic base adhesive layer;
- wherein the second middle adhesive layer is configured to move outwardly (in the X-axis) upon the body receiving a force in the Z-axis while the first film layer and third acrylic base adhesive layer stay intact or substantially intact.
