With the growing amounts of lithium ion batteries application in electric vehicles and hybrid electric vehicles, the safety issues are attracting more and more attentions. To avoid formation of lithium dendrite problems in graphite anode, high safe Li4Ti5O12 is selected as anode material. Then we choose high-voltage and high-power Li3V2(PO4)(3)/C as cathode material to increase the energy and power density of full battery system. The assembled full cell shows capacity of 178 mAh g(-1) at 0.1C rate and long lifespan of 300 cycles at 5C rate with capacity retention of 87%. The differential scanning calorimetry (DSC) shows that both cathode and anode materials generates few heat, indicating excellent thermal characterization.
