摘要：

Li4-xKxTi5O12 (x=0.02, 0.04, 0.06) were prepared via a solution method. The electrochemical performances including charge -discharge, rate property and cyclic voltammety were also investigated. The structure of the samples were characterized by X-ray diffraction. The results revealed that Li3.96K0.04Ti5O12 was well. K+ doping did not change the electrochemical process, instead enhanced the electronic conductivity and ionic conductivity. The reversible capacity and cycling performance were effectively improved.
