摘要： A secondary lithium ion battery includes an anode electrode having an anode current collector and an anode active material formed on the anode current collector, a cathode electrode having a cathode current collector and a cathode active material formed on the cathode current collector; a separator interposed between the anode electrode and the cathode electrode, and a nonaqueous liquid electrolyte. The anode active material contains lithium titanate and amorphous carbon. The hybrid anode electrode containing lithium titanate and amorphous carbon of the secondary lithium ion battery according to the present invention can reduce swelling of the secondary lithium ion battery during storage or cycle and prolong life span of the secondary lithium ion battery.
