Description

A kind of hexagonal sheet SnS2The preparation method of anode material of lithium-ion battery
Technical field
The invention belongs to anode material of lithium-ion battery technical field, more particularly to a kind of anode material of lithium-ion battery Preparation method.
Background technology
Sodium-ion battery is a kind of model electrochemical power supply, with raw material resources is abundant, relatively low cost, specific capacity and effect The advantages of rate is higher, more meets the requirement of scale stored energy application, is lifting extensive regenerative resource grid integration ability, is carrying Electric energy service efficiency high and quality of power supply aspect have application potential, simultaneously because its specific capacity is high, light weight, long lifespan and nothing The significant advantages such as Memorability, also have extensive in fields such as Aero-Space, hybrid-electric car and portable electric appts Using.In this context, sodium-ion battery causes the extensive concern in worldwide, critical material and related skill in recent years Art progress is rapid.But for lithium ion, sodium ion has larger ionic radius (0.102nm vs.0.076nm Of Li), this causes that finding suitable embedding sodium material tool acquires a certain degree of difficulty.
Stannic disulfide (SnS2) belong to IV:VI race's binary compound, a=b=0.365nm, c=0.589nm, with CdI2 The layer structure of type.This construction unit is the sandwich structure that tin ion is added by the sulphion centre of two-layer hexagonal closs packing (S-Sn-S) constitute, there are six sulphions to take AB AB hexagonal closs packings to form regular octahedron around each tin ion and be coordinated, Sn4+It is placed in two-layer S2-Between, it is Covalent bonding together in layer, there is weak Van der Waals force between layers.SnS2This stratiform There are many lattice vacancies in structure, can be used as the host lattice of " intercalation ".Superior pliability in this structure is enabled it to As substrate, by the insertion of conjugated compound, the intercalation compound with unique photoelectric property is formed.Therefore SnS2It is considered as It is the promising candidate of negative material of sodium-ion battery.With going deep into for research, it has been found that SnS2Can also with sodium from There is the alloy reaction similar with tin oxide in son, and compare SnO2With more preferable cyclical stability, therefore SnS in recent years2As sodium Ion battery cathode material is received significant attention.
Because granule-morphology is likely to affect to the chemical property of sample, particle is smaller, specific surface Product is bigger, then contact of the material with electrolyte is better, Na+Migration distance can also shorten, be so more beneficial for sodium-ion battery The lifting of negative material high rate performance, in addition, Doped ions can not only change in nano material the optics of material, electricity and The properties such as magnetics, under certain condition, can be with the pattern of controlled material.Nano material some special structures are in electrochemistry The characteristics of aspects such as energy can produce some novel.
The preparation nanometer SnS for being reported at present2The method of material be mainly chemical precipitation method [Yong C Z, Zhen N D, Li K W,et al.Size-Controlled Hydrothermal Synthesis Of SnS2Nanoparticles With High Performance In Visible Light-Driven Photocatalytic Degradation Of Aqueous Methyl Orange[J].Separation&Purification Technology,2011,81(1):101– 107.], solid reaction process [Qamar M, Gondal M A, Zh.Y.Laser-induced efficient reduction of Cr(VI)catalyzed by ZnO nanoparticles.[J].Journal of Hazardous Materials,2011, 187(4):258-263.], solvent thermal reaction method [Qihua Wang, Dewei Wang, et.al.Porous SnO2nanoflakes with loose-packed structure Morphology conserved transformation from SnS2precursor and application in lithium ion batteries and gas sensors[J].Journal of Physics&Chemistry of Solids,2011,72(6):630- 636.].Wherein chemical precipitation method can chemically react at room temperature, but the product crystallinity for generally yielding it is very poor (or It is amorphous), granule-morphology and size be irregular and broad particle distribution.Although solid reaction process have do not need solvent, Equipment is simple and the advantages of easy control of reaction conditions, but carried out in solid phase due to reacting, and generally reaction is not thorough, yield It is relatively low.Solvent thermal reaction method needs the condition of strict control solvent heat.Hydro-thermal method has incomparable excellent of many other methods More property, prepares for nano-powder in recent years and nano materials research causes the attention of people, but conventional hydrothermal reaction side Method prepares SnS2Powder has that the reaction time is more long, granule-morphology is whard to control, it is middle easily to occur.
