Anatase TiO_2 is taken as the Ti source and Li_2CO_3 as the Li source,and the molar proportion is n(Li)/n(Ti)=0.84,in constant temperature 850℃for 14h.The capacity of the offspring is 172.3mAhg~(-1).The EIS shows the impedance of 1C is much smiler than that of 0.2C and 0.5C,which means better conductivity and easier Li ion insertion-emersion and higher specific discharge capacity.
