Abstract

The invention relates to an application, an application apparatus and a preparation method for a triple-component CuO-Cu-TiO2 nanotube array composite material, and belongs to the technical field of new energy material development and research. The triple-component CuO-Cu-TiO2 nanotube array composite material is used as an electrode of a lithium ion battery; the triple-component CuO-Cu-TiO2 nanotube array composite material is used as the working electrode of the lithium ion battery; lithium foils are taken as a counter electrode and a reference electrode; a Celgard2400 film is used as a diaphragm; mixed liquid containing 1mol / L of LiPF6 is used as the electrolyte; and a button type lithium ion battery is assembled by the above parts in a glove box, wherein the glove box is filled with high-purity argon. The triple-component CuO-Cu-TiO2 nanotube array composite material is prepared by the steps of preparing a three-dimensional ordered TiO2 nanotube array by adopting a positive electrode oxidization method firstly, performing constant-voltage Cu nanoparticle deposition on the TiO2 nanotube array, and finally performing thermal treatment. The preparation method is simple in preparation process, and an extra conductive agent and a polymer binder are not required.

Description

technical field [0001] The invention relates to a three-component CuO-Cu-TiO 2 The application, application device and preparation method of nanotube array composite materials belong to the technical field of development and research of new energy materials. Background technique [0002] TiO 2 It is an important semiconductor functional ceramic material. When used as the negative electrode material of lithium-ion batteries, it has many advantages such as stable structure, small volume expansion rate, and avoiding the precipitation of metal lithium dendrites. It is a promising negative electrode candidate material. However, due to its low electrical conductivity and lithium ion diffusion rate, TiO 2 Wide application in commodity lithium-ion batteries. In order to solve the above problems, on the one hand, by constructing nanostructured TiO 2 , to increase TiO 2 specific surface area, shorten the diffusion distance of lithium ions, and improve lithium storage performance;...
