Abstract

The invention provides a method of in-situ synthesis of a porous nano Co3O4 / C anode material and belongs to the field of electrochemical. The method particularly includes steps of: synthesizing a rod-like porous cobalt-based metal organic framework through a solvothermal method, and washing, soaking and vacuum-drying a product to obtain a precursor; performing high-temperature carbonization decomposition to the precursor in a tubular furnace with an inert gas / oxygen mixture atmosphere, thus preparing a hierarchical porous nano / micro rod-like Co3O4 / C anode material. In the invention, with the porous and large-specific-surface-area cobalt-based metal organic framework, which has periodical network crystal structure, being a self-template precursor, the hierarchical porous nano / micro rod-likeCo3O4 / C anode material is prepared through the in-situ th ermal decomposition. The method has simple process. The anode material has high conductivity and specific capacity, and is excellent in cyclic stability.

Description

technical field

[0001] The invention belongs to the field of electrochemistry, and in particular relates to a method for preparing a negative electrode material of tricobalt tetroxide / carbon lithium ion battery with a multi-level porous nano-micron rod structure. Background technique

[0002] Since entering the 21st century, energy issues have always been a topic of concern to society and the government. Both developed and developing countries are aware that in the foreseeable future, if there is no energy alternative to fossil fuels, crises and wars caused by energy issues will inevitably occur. It has been less than three decades since Japan's Sony Corporation first commercialized lithium-ion batteries in 1991. During this period, lithium-ion battery technology has developed rapidly, and the advantages of lithium-ion batteries as equipment power sources and power sources have become more and more prominent. Compared with lead-acid batteries, it has high energy density, n...
