Abstract
A method for deposition of an electrolyte material on a porous substrate in which a suspension of particles having a controlled surface charge and suitable for use as an electrolyte is formed and the porous substrate, which is made of an electrode material is immersed. A voltage is applied across the suspension between an electrode in contact with the suspension and the porous substrate, whereby at least a portion of the particles migrate toward the porous substrate and are deposited on the porous substrate.
Claims13
A method for deposition of an electrolyte material on a porous substrate comprising the steps of:
- forming a suspension comprising a polar liquid medium and a plurality of particles having a controlled surface charge and suitable for use as an electrolyte;
- depositing a fugitive electrically conductive material on said porous substrate;
- immersing said porous substrate in said suspension, said porous substrate comprising an electrode material;
- applying a voltage across said suspension between an electrode in contact with said suspension and said porous substrate, such that at least a portion of said particles migrates toward said porous substrate and is deposited on said porous substrate, forming a particle layered substrate, and
- treating said particle layered substrate to cause a disappearance of substantially all of said fugitive electrically conductive material.
