Porous cellulosic substrates for lithium ion battery electrodes

Miscellaneous publication, US Patent.

An electrode material for an electrochemical cell is provided. The electrode includes a porous hydrophilic substrate, an electroactive material, and a binder. The porous hydrophilic substrate includes a plurality of voids and may be formed from cellulose or cellulosic derivative material. The electroactive material is dispersed in at least a portion of the voids of the hydrophilic substrate. In other aspects, another electrode material for an electrochemical cell is provided. The electrode includes a porous hydrophilic substrate, an electroactive material, an electrically conductive particle, and a binder. The porous hydrophilic substrate includes a plurality of voids and may be formed from cellulose or cellulosic derivative material. The electroactive material and the electrically conductive particle are dispersed in at least a portion of the voids of the hydrophilic substrate. In still other aspects, the porous hydrophilic substrate comprises a coating that is electrically conductive.
