摘　　要：锂离子电池(LIB)和钠离子电池(SIB)发展迅猛,在储能领域中被广泛研究。为了满足大规模的系统应用,其能量和功率密度还需进一步提高,其中,负极材料作为电池的重要组成部分,被认为是电池容量的主要提供者,而现商业化的石墨负极材料由于其低的理论容量(372mAh·g^(-1)),已难以满足当下能量密度的需要,因此迫切需要开发新型高比容量的负极材料。在过去的几十年里,基于转化或合金化反应的过渡金属硫化物材料以其良好的电化学性能成为极具潜力的负极材料。其中,钴基金属硫化物以它高的理论容量备受研究者的青睐(545~870mAh·g^(-1)),然而,在充放电过程中体积变化过大而导致其循环性及倍率性能较差,阻碍了它的进一步开发和应用。本文总结了近年来各种钴基硫化物(CoS,CoS_(2),Co_(3)S_(4)和Co_(9)S_(8))的研究进展,介绍了各种钴基硫化物的合成方法和电化学性能,并提出了未来提高它们电化学性能的有效途径。Over past decades,with the rapid development of society,the growth of fossil fuels depletion is huge.As a result,the human has to face the emerging energy crisis,which is regarded as the bottleneck to society progress.Meanwhile,the use of fossil fuels has also caused serious environmental pollution,which in turn threatens ecological security.Therefore,it is of great significance to develop renewable and clean energy.Some natural power,such as wind and water,have the favorable advantages of cleanliness and cheap.However,the further utilization of these powers is seriously hindered by their inherent characters,including intermittence shortage and difficultly carrying.At present,utilizing rechargeable batteries is considered as an effective strategy to deal with the above problems and has become a hot spot in scientific research and practical application.In recent years,the fast-growing technologies and new-energy vehicles market are driving iterations of developing green,cheap and high energy density energy system.In the field of energy storage,lithium-ion battery(LIB)and sodium ion battery(SIB)are developing rapidly.In order to meet the large-scale application of the system,their energy and power density need to be further improved.As an important part of the battery,the anode material is the main supplier of battery capacity,while the commercial graphite anode material has low theoretical capacity(372 mAh·g^(-1)),therefore,it is urgent to develop new anode materials with high specific capacity.In the past few decades,transition metal sulfides based on conversion or alloying reactions have become potential anode materials due to their excellent electrochemical properties.Metal sulfides(FeS,ZnS,MoS2,SnS2,VS4,SnS,Ni3S4,NiS,CuS),the promising anode materials for LIBs and SIBs,deliver the high theoretical capacity,fast conversion reaction induced by the weak metal-sulfide bonds and the safe working potential.Among them,cobalt based metal sulfides(such as CoS,CoS_(2),Co_(3)S_(4) and Co_(9)S_(8))are favored by research
