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 silicon having a plurality of channels and a surface, the plurality of channels opening to the surface; and a structural material deposited within the channels; wherein the structural material provides structural stability to the electrode during use.
Claims20
An energy storage device comprising:
- a first electrode comprising a porous material and an ion containing electrolyte, the first electrode having a plurality of channels and a surface, the plurality of channels opening to the surface;
- wherein the porous material contains a structural material substantially filling the channels and wherein the ion has a higher diffusion rate in the structural material than in the porous material.
A method of stabilizing an electrode for an energy storage device, comprising:
- providing a porous material having a plurality of channels opening to a surface of the porous material, the porous material forming at least a portion of a first electrode;
- depositing a structural material into the channels of the porous material to substantially fill the channels with the structural material;
- and
- diffusing an ion from an ion containing electrolyte into the porous material through the structural material;
- wherein the ion has a higher diffusion rate within the structural material than within the porous material.
