Abstract
A method comprising providing a first electrode layer on a first portion of a substrate, providing an electrolyte layer on the first electrode layer, and providing a second electrode layer on the electrolyte layer. At least part of a current collector layer is provided on a second portion of the substrate. An electrically insulating material is deposited on an exposed surface of the first electrode layer and an exposed surface of the electrolyte layer. An electrically conductive material is deposited on the electrically insulating material to connect the second electrode layer to the at least part of the current collector layer.
Claims18
An energy storage device comprising:
- a substrate;
- a stack on a first portion of the substrate, the stack comprising:
- a first electrode;
- a second electrode, further from the substrate than the first electrode;
- and
- an electrolyte between the first electrode and the second electrode;
- at least part of a current collector on a second portion of the substrate, different from the first portion of the substrate;
- an electrically insulating material on an exposed surface of the stack to insulate the first electrode from the second electrode;
- and
- an electrically conductive material on the electrically insulating material to connect the second electrode to the at least part of the current collector, wherein an entirety of the electrically conductive material extends substantially perpendicular to the substrate, wherein the electrically conductive material does not extend beyond a level of the second electrode.
