Abstract: This invention discloses a rechargeable nickel ion battery based on the nano-carbon materials. The said nickel ion battery is composed of a nano-carbon material cathode, a nickel anode, an separator, and an electrolyte containing nickel ions. The said nano-carbon materials are fullerene, carbon nanotube, graphene, carbon fiber, carbon foam or the composite of over two different carbon materials, etc. During discharging anodic nickel will be electrochemically dissolved as Ni2+ ions, which diffuses to the cathodic electrode/electrolyte interface through the electrolyte, and nickel ions are subsequently stored on surface of nano-carbon materials. During charging, above-mentioned process will be reverse. This battery is characterized with high capacity, fast charge and long cycle life due to the high surface area of nano-carbon materials.

Abstract: A graphite intercalation compound is disclosed in which formic acid (HCOOH) is the intercalate. The GIC may be formed by an electrochemical process using formic acid solution as both the electrolyte and as the intercalate source. The resulting formic acid GIC may be expanded by rapid heating to produce an expanded graphite product that in turn may be mechanically processed into flexible graphite.

Abstract: A ZnCl.sub.2 -graphite intercalation compound is synthesised by an electrochemical process in an aqueous solution. Flexible graphite is manufactured by exfoliating and then compressing the ZnCl.sub.2 -graphite intercalation compound into a sheet form. This processing is suitable for mass production. As no sulphuric acid is used in this method, the method reduces environmental pollution and corrosion during use.
