Abstract
Electrodes, energy storage devices using such electrodes, and associated methods are disclosed. In an example, an electrode for use in an energy storage device can comprise porous disks comprising a porous material, the porous disks having a plurality of channels and a surface, the plurality of channels opening to the surface; and a structural material encapsulating the porous disks; where the structural material provides structural stability to the electrode during use.
Claims23
An electrode comprising:
- a porous material having a plurality of channels opening to a surface;
- and
- a structural material coating on the surface that stabilizes the electrode during use.
An energy storage device comprising:
- a first electrode comprising a porous material and an ion containing electrolyte, the porous material coated with a structural material, the porous material having plurality of channels opening to a surface;
- wherein the ion has a higher diffusion rate in the structural material than in the porous material.
A method of manufacturing an energy storage device, comprising:
- providing a porous material having a plurality of channels opening to a surface of thereof;
- coating the porous material with a structural material;
- and
- diffusing an ion from an ion containing electrolyte into the porous material through the structural material;
- wherein the embedded porous material and the structural material form a first electrode and wherein the ion has a higher diffusion rate in the structural material than in the porous material.
