description A negative electrode, comprises an electrode material containing an acrylic acid derivative copolymer-based latex additive and a polymeric binder containing butadiene units. A negative electrode, for a high energy lithium ion cell, consists of an electrode material which contains a lithium intercalation compound, a conductive material and a polymeric binder and is supported on a metallic substrate. The electrode material contains a latex additive based on an acrylic acid derivative copolymer and a polymeric binder containing butadiene units. An Independent claim is also included for production of the above negative electrode by homogeneously dispersing carbon black with the latex additive in a solvent, mixing with graphite, stirring to form a homogeneous mixture, blending in the polymeric binder no earlier than the stirring step and applying the resulting electrode material onto the support substrate.
