Abstract: A secondary battery has a cylindrically wound laminate made up of a positive electrode plate, a negative electrode plate, and a separator plate interposed therebetween. The wound laminate is enclosed within a protective can, which also encloses a volume of electrolyte. The negative electrode plate includes a support member, an electrolytically active substance disposed on at least one surface of the support member, and a supplementary support embedded in the electrolytically active substance. The supplementary support is in the form of an electrically conductive network formed from a plurality of entangled and interconnected conductive members, and is used to improve the electrical conductivity of negative electrode.
