Abstract
A non-sintered electrode containing a two-dimensional conductive support covered in a layer containing an electrochemically active material and a binder which is a mixture of a styrene-acrylate copolymer and a cellulose compound chosen from methylcellulose, carboxymethylcellulose, hydroxypropylmethylcellulose, hydroxypropylcellulose and hydroxyethylcellulose. The proportion of the styrene-acrylate copolymer is less than 4% by weight of the active layer.
