DETAILED DESCRIPTION - Graphene battery comprises a reinforced shell, which is a cylindrical structure including upper and lower bottom surfaces and side wall surface. The material of the reinforced shell is made of ballistic resistant material. The inner side of the reinforced shell is divided into four spaced spaces by three partitions between the upper bottom surface and the lower bottom surface along the height direction. The three partitions are horizontally set inside the reinforced shell. The vertical distance between the two partitions is 1/4-1/3 of the vertical distance between the upper and lower partitions and the upper and lower bottom surfaces, respectively. Multiple fixed distance bars are arranged at equal intervals between two adjacent partition plates. The two ends of each of the distance bar respectively intersect perpendicularly with the two partitions at the upper and lower ends and welded and fixed on two partitions. A graphene battery cathode material is set between the upper side partition and the upper side surface. A graphene battery anode material is set between the lower partition and the lower bottom surface. An electrolyte layer is set between two of the three separators and the middle partition is provided with a through hole. Multiple graphene batteries can be assembled together. Four inserts are arranged on the upper bottom surface of the reinforcing shell. The lower bottom surface of the reinforcing shell is provided with four grooves corresponding to four inserts. The graphene battery can pass through a cutting insert and the groove, which cooperate to complete the patchwork assembly. The capacity of multiple graphene batteries increases after geometric assembly. The separator is made of a separator material. The graphene battery anode material is produced by placing 50 ml sulfuric acid solution (86%) and 15 ml concentrated nitric acid solution (89%) in an ice water bath and stirring, adding 1 g graphite raw material and 5 g solid potassium permanganate, stirring continuously to obtain graphene oxide, placing 0.3 g graphene oxide in a container containing 45 ml hydrochloric acid solution (1 mol/l), dissolving in deionized water, stirring by a stirrer for 2 hours, placing the mixture in a micro-explosion reactor, adding 5 ml potassium chlorate solution (3 mol/l) in a drop wise manner, adding 42 ml hydrogen peroxide (30%) to complete the micro-explosion reaction to obtain graphene oxide nanoroll having a crimped structure, dissolving the graphene oxide nanoroll and tin chloride in water, mixing uniformly, adding a reducing agent e.g. hydrazine hydrate or sodium borohydride, reacting for 6 hours, filtering and washing repeatedly with deionized water, drying to obtain tin dioxide/graphene nano-roll composite anode material, mixing the tinx oxide/graphene nano-roll composite anode material, binder and conductive agent in a mass ratio of 5:0.8:0.9, mixing and grinding with water to obtain graphene anode material, where the electrolyte comprises 1.8% graphene conductive additive comprising 12 pts. wt. graphene, 2 pts. wt. polyacrylonitrile fiber, 4 pts. wt. dispersant, 8 pts. wt. ethanol and 0.3 pts. wt. titanium carbide. The graphene cathode material is produced by: (a) adding graphene into a penetrant for dispersion, where the penetrant is a non-ionic chelate, (b) manganese ion intercalation reaction by placing a mixture of completely contacted manganese ions in a reaction vessel for iontophoresis reaction, and (c) washing the electrode after the reaction is completed. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the graphene battery.
