| titleOfInvention | Lithium Cobalt Oxide Hollow Gunnano Structure Using Carbon Template Sacrificial Method and Its Manufacturing Method |
| abstract | The present invention relates to a lithium cobalt oxide-based hollow sphere nanostructure using a carbon template sacrificial method and a method for producing the same. Specifically, a silica template is prepared, and the prepared silica template is 40 wt% of tetrahydrofuran of phenol resin. After impregnating with the solution, a porous carbon template is prepared through heat treatment and removal of the silica template, and the porous carbon template is impregnated with a lithium / cobalt mixed salt solution in which lithium is present in excess of cobalt, followed by calcination. Lithium / cobalt salts impregnated in the porous carbon template is oxidized, and the carbon template is removed by sintering heat treatment of an oxygen atmosphere to produce a lithium cobalt oxide nanostructure in the form of a hollow sphere.n n n The surface area of the hollow lithium cobalt oxide sphere nanostructures ranges from 200 m 2 / g to 600 m 2 / g, and the surface area of the hollow 150 nm lithium cobalt oxide (LiCoO 2 ) sphere structure is 582 m 2 / g. It is 132.78 mAh / g at 0.2C and 122.0845 mAh / g at 5C, and the charge and discharge capacity retention capability of 5C vs 0.2C is 91.9%, which is very good.n n n n Carbon template sacrificial method, lithium secondary battery, positive electrode active material, lithium cobalt oxide based sphere structure, lithium cobalt oxide hollow sphere nano structure, three-dimensional porous carbon template |
