USE - The graphite-modified lithium manganate cathode material is used for lithium-ion battery. ADVANTAGE - The graphite-modified lithium manganate cathode material has excellent stability, uniformity, and high temperature characteristics, and provides battery having excellent charging and discharging characteristics at normal temperature and high temperature. DETAILED DESCRIPTION - A graphite-modified lithium manganate cathode material comprises 500 pts. wt. lithium manganese oxide, 2-3 pts. wt. graphene, 2-3 pts. wt. zeolite, 3-4 pts. wt. copper, 1-2 pts. wt. sodium thiosulfate, 4-5 pts. wt. modified silver and water. The modified silver powder contains raw material comprising 100 pts. wt. silver, 1-2 pts. wt. nanocarbon, 2-3 pts. wt. calcium carbonate powder, 2-3 pts. wt. tripolyphosphate, 1-2 pts. wt. montmorillonite powder, 1-2 pts. wt. crosslinker triallyl cyanurate, 1-2 pts. wt. smashing blade acid, 1-2 pts. wt. oxygen, and 2-3 pts. wt. tantalum pentoxide. The graphite-modified lithium manganate cathode material is manufactured by mixing raw materials uniformly, heating the mixture at 50-55 degrees C, milling for 1-2 hours, to obtain uniform dispersion powder, sintering the powder at 550-580 degrees C for 2-3 hours. An INDEPENDENT CLAIM is included for manufacture of graphite-modified lithium manganate cathode material.
