Description
Technical Field
The application belongs to the technical field of transition metal phosphide composite materials, and particularly relates to a preparation method and application of a porous molybdenum phosphide/carbon fiber composite material.
Background
The performance of the sodium ion battery is slightly worse than that of the lithium ion battery during high-rate discharge, but the sodium ion battery has the advantages of large-scale energy storage of a power grid and other energy storage fields because of low manufacturing cost, stable material structure performance and safety during use.
Transition metal phosphide is based on the energy storage mechanism of conversion reaction, and the ideal selection of the anode material of the sodium ion battery is called as the higher theoretical capacity and the lower sodium storage voltage, but the commercialization progress of the phosphide is hindered by the poor rate capability and the larger volume expansion in the cycle. The porous structure can be used as an effective modification means to effectively relieve the stress generated by the volume effect of the electrode in the charge-discharge cycle, prevent the material from being pulverized, and promote the electrolyte to be fully infiltrated on the surface of the electrode.
The traditional pore-forming method usually adopts a route of using a hard template in synthesis and then removing the hard template through a reagent, for example, in a patent (CN110479332A), a phosphorus source/molybdenum source/carbon source is used as a raw material, sodium chloride is used as a pore-forming agent, and porous molybdenum phosphide nanosheets are obtained through freeze drying, calcining and washing, so that the process is complicated and a large amount of template agent is consumed. Or a method of self-assembly of a large amount of surfactants is used for constructing a pore structure, for example, in the patent (CN110350181A), a nano porous silicon negative electrode material is prepared by etching and pore-forming nano silicon particles by using hydrofluoric acid, the raw material needs to be strictly pretreated, and the use of the hydrofluoric acid consumes active components and generates corrosive waste acid.
