▎ 摘  要

NOVELTY - A graphite/lithium aluminate/graphene composite material preparing method involves reacting an aluminum hydroxide solution with sodium hydroxide and lithium carbonate to obtain a solution. Graphite is added to the mixed solution and dispersed mixed solution and uniformly dispersed, and water is evaporated to obtain graphite/lithium aluminate composite powder body. Nickel catalyst and graphite/lithium aluminate composite powder are mixed, and protective gas is filled, and carbon source gas and a mixed gas of inert gas is introduced, and cooled to room temperature to obtain finished product. USE - Method for preparing graphite/lithium aluminate/graphene composite material for use in lithium ion battery (claimed). DETAILED DESCRIPTION - A graphite/lithium aluminate/graphene composite material preparing method involves reacting an aluminum hydroxide solution with sodium hydroxide and lithium carbonate, at 40-60 degrees C for 3-48 hours to obtain a solution containing lithium aluminate. Graphite is added to the mixed solution and uniformly dispersed mixed solution and uniformly dispersed under a reduced pressure condition at 40-100 degrees C, and water is evaporated to obtain graphite/ lithium aluminate composite powder body. Nickel catalyst and graphite/lithium aluminate composite powder are mixed, and protective gas is filled, and heated at 500-1200 degrees C, and inletting protective gas is stopped, and carbon source gas and a mixed gas of inert gas is introduced, and the mixture is kept for 20-120 minutes, and cooled to room temperature to obtain finished product.
