The invention is an electric vehicle colloidal storage battery, comprising battery tank, battery cover, anode plate, cathode plate, glass fiber baffle, colloidal electrolyte, safety explosion-proof valve, terminals and bus, where the anode and cathode plates are composed of positive and negative grids and positive and negative active matters, respectively, the grids are of a special designed structure, the anode active matter is added with tin dioxide and gas phase silicon dioxide, and the colloidal electrolyte uses vitriol as the principal and uses the mixture of gas phase silicon dioxide and functional high molecular polymer as gel. And it has characters of high specific energy, heavy discharge current, excellent overcharge and overdischarge resistances, long circulating service life, completely applied to electric vehicles, such as electric buses, mixed electric buses, electric cars, electric forklifts, purely electric tourist cars, and electric motor cars.
