摘      要：Ribbon-like Cu doped V6O（13） was synthesized via a simple solvothermal approach followed by heat treatment in air.As an cathode material for lithium ion battery,the ribbon-like Cu doped V6O（13 ）electrode exhibited good capacity retention with a reversible capacity of over 313 m Ah·g^-1 for up to 50 cycles at 0.1C,as well as a high charge capacity of 306 m Ah·g^-1 at a high current rate of 1 C,in comparison to undoped V6O（13 ）electrode（267 m Ah·g^-1 at 0.1C and 273 m Ah·g^-1 at 1 C）.The high rate capability and better cycleability of the doped electrode can be attributed to the influence of the Cu ions on the mophology and the electronic conductivity of V6O（13） during the lithiation and delithiation process.
