Abstract
A method comprising providing, on a substrate, a stack for an energy storage device, the stack comprising a first electrode layer, a second electrode layer, and an electrolyte layer between the first electrode layer and the second electrode layer. A groove is formed at least through the second electrode layer and the electrolyte layer such that the groove is wider in the second electrode layer than in the electrolyte layer. An electrically insulating material is provided in the groove. An electrically conductive material is provided in the groove, on the electrically insulating material.
Claims4
An energy storage device formed by a method comprising:
- providing, on a substrate, a stack for an energy storage device, the stack comprising a first electrode layer, a second electrode layer, and an electrolyte layer between the first electrode layer and the second electrode layer;
- forming a groove at least through the second electrode layer and the electrolyte layer such that the groove is wider in the second electrode layer than in the electrolyte layer;
- providing an electrically insulating material in the groove;
- and
- providing an electrically conductive material in the groove, on the electrically insulating material, in direct contact with a portion of the electrolyte layer and in direct contact with the second electrode layer.
An energy storage device comprising:
- a substrate;
- a stack on the substrate, the stack comprising:
- a first electrode;
- a second electrode;
- and
- an electrolyte between the first electrode and the second electrode, the first electrode closer than the second electrode to the substrate, the electrolyte comprising a first portion overlapped by the second electrode and a second portion not overlapped by the second electrode;
- an electrically insulating material in contact with the first electrode and the electrolyte;
- and
- an electrically conductive material in direct contact with the second portion of the electrolyte and the second electrode.
