NOVELTY - Vanadium/molybdenum trioxide/graphene complex electrochromic thin-film material comprises vanadium pentoxide sol, molybdenum trioxide sol and graphene raw materials, where the molar ratio of vanadium pentoxide in vanadium pentoxide sol and molybdenum trioxide in molybdenum trioxide sol is 1:0.01-0.02 and the mass ratio of vanadium pentoxide and graphene in the vanadium pentoxide sol is 1:0.03-0.05. USE - Used as vanadium/molybdenum trioxide/graphene complex electrochromic thin-film material. ADVANTAGE - The film has high electrochemical properties and electrochromic properties. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing vanadium/molybdenum trioxide/graphene complex electrochromic thin-film material comprising (a) preparing complex sol by selecting vanadium pentoxide sol, molybdenum trioxide sol and graphene raw material, adding molybdenum trioxide sol in a dropwise manner, mixing vanadium pentoxide sol, stirring for 30 minutes, sealing, allowing to stand, aging for 3 days, adding graphene into the mixed sol by cell disruptor and ultrasonically dispersing, to obtain vanadium/molybdenum trioxide/graphene complex sol-gel, (b) adding vanadium/molybdenum trioxide/graphene complex sol by dip-coating in a film and drying.
