Lithium-sulfur cell is one of the hot spot of high-capacity lithium ion cell research in recent years, with traditional lithium ion battery oxygen Compound electrode material (such as LiCoO2, LiFePO4Deng) compare, sulphur anode specific capacity, energy density and in terms of all With unique advantage.Theoretically, LiS is generated after lithium reacts completely with sulphur2, it can be achieved that 2 electron reactions, and the original of elemental sulfur Son amount is obviously lighter than the inlaid scheme positive electrode of current commercial Li-ion battery, and electrode theory specific capacity is reachable 1675mAh/g reaches 2600Wh/kg with lithium/sulfur rechargeable battery system theoretical energy density of sulphur and lithium metal building.
The electrochemical reaction of sulphur anode includes multi-step redox reaction, the complicated phase transfer of simultaneous sulfide Process, when electric discharge, solid phase elemental sulfur S8(s) dissolution occurs first and forms liquid phase elemental sulfur S8(l), then sulfide linkage is gradually broken quilt Reduction, then according to reaction equation: S8(l)+2e-→S8 2-、3S8 2-+2e-→4S6 2-、2S6 2-+2e-→3S4 2-、S4 2-+2e-→ 2S6 2-、S2 2-+2e-→S2-, gradually generate a series of polysulfide anion (S of soluble moderate-length chainsn 2-), equation: S8(l) +2e-→S8 2-、3S8 2-+2e-→4S6 2-、2S6 2-+2e-→3S4 2-, indicate liquid phase simple substance S8Gradually it is reduced into Sn 2-(4≤n≤ 8), they are soluble in the electrolytic solution, as shown in following the equation: S4 2-+2e-→2S6 2-、S2 2-+2e-→S2-、S2 2-+2Li+→ Li2S2↓、S2-+2Li+→Li2S ↓, with the intensification of depth of discharge, long-chain polysulfide ion is further reduced, and generates lower valency S2 2-And S2-, in conjunction with lithium ion, generate insoluble final state product Li2S2And Li2S；And during the charging process, then occur Reversible opposite reaction, discharging product Li2S2And Li2S is gradually oxidized to long-chain polysulfide lithium, is finally oxidised to elemental sulfur；Lithium There are two typical discharge platforms for sulphur battery tool, and under normal circumstances, high voltage platform is down to 2.1V, corresponding elemental sulfur from 2.45V S8By a series of solvable polysulfide anion, S is ultimately produced4 2-, the voltage of low-voltage platform maintains 2.1V~1.7V, shows The S of generation4 2-Finally it is reduced into Li2S2And Li2S。
Above-mentioned oxidationreduction mechanism makes sulphur anode can break through the limitation of traditional intercalation compound capacity, shows Much higher than the capacity of traditional positive electrode, but there are the following difficulties for being badly in need of overcoming for the battery system: due to the insulating properties of sulphur Problem, elemental sulfur and its discharging product are all that (conductivity of sulphur is only 5 × 10 at room temperature for the insulator of electronics and ion-30S/ Cm), electronics and ion are difficult in anode transmission, cause room temperature electrochemical reaction kinetic rate very slow.
