Abstract
An electrically-conductive collector element (23) in a polymeric laminate lithium ion rechargeable battery is cleaned of surface oxides and coated with an adherent conductive polymer film (34) which is substantially inert to battery electrolyte components and prevents recurrent formation of insulative collector surface oxides, thereby maintaining effective electrode/collector electrical conductivity and significantly reducing internal battery resistance.
