挥去能源危机的阴霾并开发绿色环保的新能源，实现人类的可持续化发展已成为世界各国的共同目标。随着便携式电子设备和大型电动设备的迅速发展，拥有高能量密度、高功率密度、无记忆效应等众多优点的锂离子电池的市场规模也在不断扩大【1】。对于这种发展前景非常好的二次电池而言，人们需要的是更高水平的材料来进一步提高锂离子电池的能量密度、功率密度以及循环寿命等。

石墨作为主流的商业化电极材料,虽然具有循环稳定、电压平台低等优点,但其较低的理论容量（372 m Ah /g）还是不能达到下一代锂离子电池的要求【2】。电极材料的组成与微观形貌，直接决定了节能元件的电化学性能。硫与过渡金属结合生成的过渡金属硫化物，因为其特殊的成键方式，较复杂结构，使其具有良好的导电性、热稳定性、柔韧性等，作为一种宽禁带的半导体材料，成为了科学家的研究热点。因为其较高的理论容量值，近年来在燃料电池、锂离子电池、超级电容器等领域备受关注。因为过渡金属硫化物独有的电子结构和优异的理化性质，使其在与石墨烯结合后表现出了更加优良的电化学性能。

It has become the common goal of all countries in the world to get rid of the haze of the energy crisis and develop green and environmentally friendly new energy sources to realize the sustainable development of mankind. With the rapid development of portable electronic equipment and large-scale electric equipment, the market scale of lithium-ion batteries with many advantages such as high energy density, high power density, and no memory effect is also expanding. For such secondary batteries with very good development prospects, people need higher-level materials to further increase the energy density, power density and cycle life of lithium-ion batteries.

As a mainstream commercial electrode material, graphite has the advantages of stable cycle and low voltage platform, but its low theoretical capacity (372m Ah / g) still cannot meet the requirements of the next generation of lithium ion batteries. The composition and micro-morphology of the electrode material directly determine the electrochemical performance of energy-saving components. The transition metal sulfide formed by the combination of sulfur and transition metal, because of its special bonding method and relatively complex structure, makes it have good conductivity, thermal stability, flexibility, etc. As a semiconductor material with a wide band gap, It has become a research hotspot of scientists. Because of its high theoretical capacity value, it has received much attention in recent years in the fields of fuel cells, lithium-ion batteries, and supercapacitors. Because of the unique electronic structure and excellent physical and chemical properties of the transition metal sulfide, it shows more excellent electrochemical performance after being combined with graphene.
