Title: Binders for silicon electrodes in lithium-ion batteries

Abstract

An electrode for a lithium-ion electrochemical cell comprises silicon particles and carbon particles coated on a conductive current collector. The silicon and carbon particles being bound to each other and to the current collector by a cross-linked binder formed from a combination of a poly(carboxylic acid) such as poly(acrylic acid) and a branched polyethyleneimine. A method of preparing the anode also is described.
