Description
Technical Field
The invention belongs to the technical field of new materials, and particularly relates to a preparation method for constructing a nanowire-shaped manganese selenide/carbon composite material based on an MOFs template.
Background
With the increasing exhaustion of fossil energy represented by petroleum and the increasing environmental pollution caused by the combustion of fossil energy, people urgently need a sustainable and renewable clean energy. The lithium ion battery has the advantages of high energy density, long cycle life, environmental friendliness and the like, is distinguished from a plurality of new energy sources, and has wide application in the fields of mobile electronic equipment, new energy automobiles and the like. However, the negative electrode material of the current commercial lithium ion battery is graphite, the theoretical capacity of the graphite is only 372mAh/g, the capacity requirement of large electronic equipment such as an electric automobile cannot be met, and the application and development of the lithium ion battery are limited. Scientists have developed a variety of negative electrode materials to improve the capacity of lithium ion batteries, such as carbon materials, transition metal oxides, transition metal sulfides, transition metal selenides, and the like.
Compared with transition metal oxides and transition metal sulfides, the transition metal selenide not only has high volume specific capacity and mass specific capacity, but also has low voltage platform, small polarization and better conductivity, and is a potential lithium ion battery cathode material. However, similar to the transition metal oxide, the transition metal selenide may undergo a large volume change due to intercalation and deintercalation of lithium ions during charging and discharging, thereby crushing and pulverizing the active material, causing the active material to be separated from the current collector, losing electrical contact, causing capacity fading and cycle performance degradation. In addition, the transition metal phosphide has poor electronic conductivity, hinders the rapid transfer of electrons in the active material, and limits the electrochemical response of the active material, so that the rapid charge-discharge capacity and the rate capability of the active material are poor.
At present, research for improving the lithium storage performance of the transition metal selenide mainly focuses on two aspects, one is to compound the transition metal selenide with carbon materials such as graphene and carbon nanotubes, and the like, and by utilizing the excellent conductivity and mechanical property of the carbon materials, the conductivity of the transition metal selenide is improved and the stress generated by volume expansion in the circulation process is absorbed; the other method is to prepare the transition metal selenide with the nano-scale and porous structure, enlarge the specific surface area of the material, increase the contact area of the electrode material and the electrolyte, shorten the diffusion path of electrons and lithium ions and buffer the stress generated by volume expansion.
The metal organic framework compounds, called MOFs for short, are organic-inorganic hybrid materials with molecular pores formed by self-assembly of organic ligands and metal ions through coordination bonds. The MOFs have the advantages of porosity, large specific surface area, component adjustability and the like, so that the MOFs have wide application prospects in the fields of gas collection and storage, gas separation, catalysis, sensors, energy storage and the like, and have attracted wide attention since the birth of the last ninety years. Meanwhile, due to the porous structure and the organic framework of the MOFs and the abundant adjustability of metal ions, the MOFs can be used as a precursor for preparing porous materials, such as carbon materials, metal oxides, metal sulfides, metal selenides and the like. The porous material derived from the MOFs can retain the porous structure and the large specific surface area of the MOFs, meanwhile, the organic framework can be converted into porous carbon under high-temperature inert atmosphere, and the porous carbon/metal compound composite material can be prepared under the condition that no external carbon source is introduced.
The technical problems that the nanowire of the conventional linear manganese selenide/carbon composite material is easy to break, uneven in appearance, poor in dispersity and easy to agglomerate, the purity of the manganese selenide/carbon composite material is low, the yield is low, the electricity storage capacity is small, the cycle life is short, the stability in the using process is poor, the current is easy to fluctuate, and the like exist in the conventional linear manganese selenide/carbon composite material are urgently needed to be solved.
