In recent decades, significant problems such as population, environmental pollution and energy shortage appear in the world. With the development of industry, people pay more and more attention to the utilization and storage of energy. In the prior art, lithium ion batteries provide the highest energy density, however, since the storage capacity of lithium batteries is limited and the application range is wide, the subsequent products of lithium batteries are urgently needed. Sodium, has a large reserve and is much less expensive than lithium. In addition, sodium and lithium belong to the same group in the periodic table, and the energy storage mechanism of a sodium-ion battery is similar to that of a lithium-ion battery. In recent years, sodium ion batteries have attracted the attention of researchers. Since sodium ions have a larger ion radius than lithium ions, materials widely used as anode materials for lithium ion batteries are not suitable for sodium ion batteries. At present, it is of great importance to develop anode materials suitable for sodium ion batteries.
The reaction mechanism of the negative electrode material of the sodium-ion battery generally comprises: intercalation, transformation and alloying reactions. As conversion-reaction anode materials, e.g. transition metal sulfides NiSx，CoSxCuS, has excellent electrochemical properties due to its high theoretical capacity. In addition, bimetallic sulfides can provide a richer redox reaction and therefore exhibit better electrochemical performance than monometallic sulfides. Recently, studies such as CoMoS have been conducted4the bimetallic sulfide is used for some battery applications, but due to a huge volume effect, the bimetallic sulfide is easy to break in the charging and discharging process, so that the battery capacity is attenuated, and the practical application of the material is greatly influenced. Therefore, the research on the negative electrode material of the sodium-ion battery with high energy and power density, long cycle life, low cost and high safety performance is of great significance.
