Claim Text:
1. A method of forming a cathode for a Li-ion battery comprising: preparing an aqueous solution of carboxymethylcellulose (CMC); mixing together a Li-containing cathode material and carbon black to form a first mixture; providing an aqueous solution of polyacrylic and water; combining said first mixture with said aqueous solution of CMC, said aqueous solution of polyacrylic and said water, and mixing to form a slurry; coating a conductive substrate with said slurry, forming a cathode layer on said conductive substrate; and drying said cathode layer; wherein the polyacrylic in said aqueous solution of polyacrylic is characterized by a glass transition temperature, Tg, in the range of about −20° C. to about 0° C.
