Abstract: A composition including a polymeric binder for the negative electrode of a secondary energy storage device is provided. The polymeric binder provides a matrix for particulate electrode-forming materials, which may include an active material and a conductive material. The polymeric binder contains acid functional groups. The polymeric binder also contains other functional monomers, which also may contribute to the performance of the polymeric binder in the negative electrode.

Abstract: An electrode forming slurry composition is provided. The electrode-forming slurry compositions include a) from 10 to 300 parts of one or more particulate electrode-forming materials; b) from 0.1 to 60 parts of polymeric latex particles; and c) 100 parts water. The electrode forming slurry compositions can form an electrode, an anode for a non-aqueous secondary battery, in particular a lithium ion battery. The polymeric latex particles b) include i) at least one ethylenically unsaturated monomer comprising at least one acid functional group; and include ii) no fluorinated monomer or butadiene monomer polymerized therein. Also provided is an anode including the electrode forming slurry composition in dried form.
