Abstract
A three dimensional electrode structure having a first layer of interdigitated stripes of material oriented in a first direction, and a second layer of interdigitated stripes of material oriented in a second direction residing on the first layer of interdigitated stripes of material. A method of manufacturing a three dimensional electrode structure includes depositing a first layer of interdigitated stripes of an active material and an intermediate material on a substrate in a first direction, and depositing a second layer of interdigitated stripes of the active material and the intermediate material on the first layer in a second direction orthogonal to the first direction.
Claims10
A method of manufacturing a three dimensional electrode structure, comprising:
- depositing a first layer of contiguous, separated, interdigitated stripes of an active, electrode, paste material and an intermediate material on a substrate in a first direction, the intermediate material being one of either a liquid or gel electrolyte, or a porous material filled with electrolyte;
- and
- depositing a second layer of contiguous, separated, interdigitated stripes of the active material on the first layer of interdigitated stripes of material and the intermediate material on the first layer in a second direction orthogonal to the first direction.
