Composite positive pole material, battery-super electric capacity energy storage means and preparation method

The invention relates to a novel energy accumulator, i.e. a battery--- a super capacity energy accumulator, and the composite positive material is obtained by situ composition of the resources for fabricating lithium-contained composite metal oxide materials and porous carbon materials. The resources for fabricating lithium-contained composite metal oxide materials and porous carbon materials are ground in acetone or ethanol to form the uniform flow state with the solvent being volatilized, preheated in the inert atmosphere, ground uniformly after naturally cooling, roasted in the inert atmosphere again, and cooled down to the room temperature to obtain the target product. The composite anode is used as the anode of the battery--- the super capacity energy accumulator, lithium-contained composite metal oxide material or lithium ion-embeddable inorganic oxide material is used as the cathode of the battery--- the super capacity energy accumulator, non-aqueous lithium salt organic solution is used as the electrolyte solution, and an electron-insulation diaphragm through which ions can pass is provided between the anode and the cathode. The novel energy accumulator has better energy density and performance on service life, and after 100 times of circulations, the capacity is lost by 9.18 percent. The energy accumulator in the invention has both the properties of super capacitors and rechargeable batteries.
