ABSTRACT:
The present invention is directed to a high capacity electrode paste and process for the fabrication of same. The resultant paste has a plurality of electrochemically active particles dispersed in solution. Additionally, during fabrication of the electrode paste, the electrochemically active material is subjected to a grinding step. After grinding the material to the desired particle sizes, the grinding medium is removed. However, the particles remain dispersed in solution, even after removal of the grinding medium. Accordingly, each of the individual particles have at least a portion of their respective surfaces in contact with the solution.
