More Information
Summary:The invention discloses a titanium dioxide nano-rod cathode material of a power lithium ion battery and a preparation method thereof. In the method, a titanium foil is used as a base, a solvent thermal reaction is adopted, and a dense salt, methylbenzene and n-butyl titanate are used as raw materials to form a long and thin rutile type titanium dioxide nano-rod with a monocrystalline structure. The rutile type titanium dioxide nano-rod prepared by the method has higher charge-discharge capacity, multiplying factor and cycle performance when the electric potential interval is 0.01 to 2.5 V.
