The invention discloses a glucose-assisted method for preparing a high-performance Fe-doped two-dimensional porous NiO electrode material. Using nickel chloride hexahydrate and ferric chloride hexahydrate as raw materials and glucose as an auxiliary additive, a two-dimensional porous NiO electrode material with Fe doping was prepared by high-temperature sintering method. The method of the invention is very simple, low in cost, high in yield, and easy to control the preparation conditions. The prepared electrode material is composed of a two-dimensional porous sheet composed of primary nanoparticles, and an appropriate amount of Fe doping can significantly improve the cycle stability of the NiO electrode material. and rate performance.
Description
Glucose-assisted preparation of Fe-doped two-dimensional porous NiO electrode materials with high lithium storage performance method technical field The invention belongs to the technical field of chemical power supply, be specifically related to a kind of preparation of high-performance negative electrode material for lithium ion battery. preparation method. Background technique NiO material has the theoretical specific capacity of 718mAh / g, high volume energy density, abundant natural resources, safety It has good sex and has attracted the attention of scientific researchers in the past two years. However, NiO is a P-type semiconductor, and its poor conductivity greatly affects The cycle performance and rate performance when it is used as a negative electrode material for lithium ion batteries were investigated. In addition, NiO is used as a negative material for lithium ion batteries During the intercalation / delithiation process, the material will undergo obvi...
