NOVELTY - A current collector device for use in a battery, comprises a substrate (30) with at least one surface, where the surface coated with a mixture of carbon nanotubes and secondary conducting particles, where at least some carbon nanotubes form electrically conductive bridges between at least some of the secondary conducting particles, where the substrate is non-woven fabric, fabric like material, grid or veil.    USE - As current collector device for use in a battery (claimed), which is used in a variety of electronic devices, such as portable computers, portable tools, calculators, watches, cordless telephones, radios, tape recorders and security systems.    ADVANTAGE - The use of porous, non-metallic substrate allows the active cathode material to reside inside a conductive matrix. The flexible substrates retain good thermal properties, and are flexible enough to reduce the risk of hard shorting. Thus flexible substrates can lead to safer batteries, because hard shorting, caused by inflexible substrates, can lead to thermal runaway and resulting dangerous battery overheating. Thermal shorting and thermal runaway can also be caused by burr formation, which is often accidentally produced by during the substrate cutting and slitting process; provides additional safety i.e. flexible substrates are much less prone to bun formation during slitting and cutting. The lightweight battery material enables production of improved lightweight battery that has large capacity, high voltage and excellent charge-discharge cycle properties. Thus the improved battery is free from decomposition of solvents of electrolytic solution.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for creating a current collector for a battery, involving creating a dispersion, where the dispersion comprising a mixture of carbon nanotubes, conductive secondary particles, and a curable binder; applying the dispersion to a porous substrate with a substrate exterior surface and a substrate interior matrix surface such that the dispersion is absorbed onto both the substrate exterior surface and substrate interior matrix surface of the substrate, forming a substrate with coated dispersion; curing the substrate with absorbed dispersion so that the curable binder binds the mixture of carbon nanotubes and conductive secondary particles to the substrate exterior surface and substrate interior matrix surface, where the cured substrate with absorbed dispersion, at least some of the nanotubes form conductive links between at least some of the conductive secondary particles.
