More Information
Summary:A current collector (21, 22) according to the invention comprises:- at least two conductive materials among the following: carbon based materials and water-soluble or water-dispersible conductive polymers, said conductive materials including at least one carbon based material and being in an total amount in the range from about 70 to 99.5 per weight % relative to the total weight of the current collector (21, 22),- at least one binder comprising a lignocellulosic material selected from the group consisting of cellulose fibres, refined cellulose fibres, cellulose microfibrils or microfibrillated cellulose (MFC), cellulose nanofibrils and lignin, in an amount in the range from about 0.5 to 30 weight % relative to the total weight of the current collector (21, 22).
