The presently disclosed and/or claimed inventive process(es), procedure(s), method(s), product(s), result(s), and/or concept(s) (collectively hereinafter referred to as the "presently disclosed and/or claimed inventive concept(s)") relates generally to the composition of a binder for use in battery electrodes and methods of preparing such. More particularly, but not by way of limitation, the presently disclosed and/or claimed inventive concept(s) relates to a binder composition containing an ionizable water soluble polymer and a redispersible powder containing a latex, a protective colloid, and an anticaking agent for use in the production and manufacture of electrodes of a lithium ion battery. Additionally, the presently disclosed and/or claimed inventive concept(s) relates generally to the compositions and methods of making electrodes, both anodes and cathodes, with a binder composition containing an ionizable water soluble polymer and a redispersible powder.
