Abstract
Methods for manufacturing an energy storage device. Such methods comprise providing a first stack on a first side of a substrate and a second stack on a second side of the substrate, opposite to the first side of the substrate. In examples, a first and third groove are formed in the first stack, with different depths than each other, and a second and fourth groove are formed in the second stack, with different depths than each other. In other examples, a first groove is formed in the first stack and a second groove is formed in the second stack, in substantial alignment with the first groove but with a different depth than the first groove.
Claims12
A method for manufacturing an energy storage device, the method comprising:
- providing a first stack on a first side of a substrate, the first stack comprising a first electrode layer, a second electrode layer, and a first electrolyte layer between the first electrode layer and the second electrode layer, the first electrode layer closer than the second electrode layer to the first side of the substrate;
- providing a second stack on a second side of the substrate, opposite to the first side of the substrate, the second stack comprising a third electrode layer, a fourth electrode layer, and a second electrolyte layer between the third electrode layer and the fourth electrode layer, the third electrode layer closer than the fourth electrode layer to the second side of the substrate;
- forming a first groove in a first side of the first stack, the first side of the first stack opposite to a second side of the first stack in contact with the first side of the substrate, the first groove having a first depth;
- forming a second groove in a first side of the second stack, the first side of the second stack opposite to a second side of the second stack in contact with the second side of the substrate, the second groove having a second depth;
- forming a third groove in the first side of the first stack, the third groove having a third depth different from the first depth;
- and
- forming a fourth groove in the first side of the second stack, the fourth groove having a fourth depth different from the second depth.
