TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Agent: The non-metallic conducting agent comprises conductive carbon. The conductive carbon is graphite, carbon black, Denka Black, Lonza carbon, Super-P, activated carbon MSC30, and carbon nanotube.    TECHNOLOGY FOCUS - POLYMERS - Preferred Material: The polymer package further comprises a polymer film (140) and polymer adhesive layer (150) between polymer films (110,120) and polymer films (120,130). A combined film battery package and current collector has conductive layer containing non-metallic conducting agent and binder. Preferred Layer: The polymer film (110) is formed of a polymer or blend of two or more polymers chosen from polyethylene, polypropylene, polyvinylidene fluoride, polytetra fluoroethylene and polystyrene. The polymer film (120) is formed of a polymer or a blend of two or more polymers chosen from polyvinyl chloride, polyvinylidene chloride, nylon, polyacrylonitrile and polyvinyl alcohol. The polymer film (130) is formed of polyester-based polymer, preferably polyethylene terephthalate or polybutylene terephthalate.The polymer film (140) is formed of a polymer or a blend of two or more polymers chosen from polyethylene, polypropylene, polyvinylchloride, polyvinylidene chloride, polyvinylidene fluoride, copolymer of vinylidene fluoride and hexafluoropropylene, copolymer of vinylidene fluoride and trifluoroethylene, copolymer of vinylidene fluoride and tetrafluoro ethylene, nylon, polyacrylonitrile, polyvinyl alcohol, and ethyl vinyl alcohol. The polymer adhesive layer is formed of a polymer or blend of two or more polymers chosen from polyethylene, polypropylene, polyurethane and acrylate-based polymer. The acrylate-based polymer is polymethylacrylate, polyethylacrylate, polymethyl methacrylate, polyethyl methacrylate, polybutylacrylate and polybutyl methacrylate. The binder is a polymer or a blend of two or more polymers chosen from polyethylene oxide, polypropylene oxide, starch, polyacrylic acid, polyvinyl alcohol, polyvinyl acetate, cellulose, cellulose acetate, carboxymethyl cellulose, methyl cellulose, ethyl cellulose, butyl cellulose, polyvinylchloride, polyvinylidene chloride, polyvinylidene fluoride, polytetra fluoroethylene and Nafion (RTM: perfluorosulfonate).
