Description
Technical field
The present invention relates to lithium-sulfur cell technical field more particularly to a kind of single-ion conductor polymer lithium-sulfur cells.
Background technique
Elemental sulfur is up to 1675mAh g as the theoretical specific capacity of electrode material-1, the lithium sulphur electricity that is matched with lithium metal
The energy density in pond reaches 2600Wh kg-1, the energy density of the sodium-sulphur battery matched with metallic sodium is up to 1262Wh kg-1,
Metal sulphur battery is a kind of potential high specific energy secondary power supply.But the electronic conductivity of elemental sulfur is very low, about 10-30S
m-1, become and restrict its matter of utmost importance as positive electrode.For the low problem of the electronic conductivity of elemental sulfur, solution point
It is two kinds, the first is the size for reducing sulfur granules, promotes the generation of electron tunneling effect;Second is to become active material
Liquid greatly reduces the interface resistance between collector and solution.Former strategy derives two kinds of specific ways, first is that
Sulfur granules are embedded in micropore carbon carrier, carbon-supported nano sulphur is obtained;Second is that polyacrylonitrile is calcined after being blended with elemental sulfur, by sulphur content
Son is dispersed in the form of chemical bond and is fixed in the composite.The advantage of this strategy is that the electrolysis of esters system still can be used
The battery assembly technology of matter and maturation, the disadvantage is that the carrying capacity of active material is lower, about 35wt%, synthesis technology is cumbersome, and
And still there is a degree of decaying.Latter strategy be replace currently used esters electrolyte with ethers electrolyte, the result is that
The polysulfide dissolution that preliminary electrochemical reduction generates in the electrolytic solution, and is conducive to further electrochemical oxidation.It is this
The advantage of strategy is that the preparation process of anode is simple, the disadvantage is that penetrate porous polymer electrolyte diaphragm right for soluble polysulfide
Redox reaction, i.e. shuttle effect occurs with lithium metal afterwards.

Application.Certainly, problem is to be dispersed in the form of chemical bond even if sulphur in the carrier, and there are still capacity in esters electrolyte
The problem of decaying.2002, Jiulin Wang etc. was calcined 6 hours after polyacrylonitrile is blended with elemental sulfur at 280-300 DEG C,
The mass fraction of sulphur is 53.41% in obtained composite material, in 1M LiPF6EC/DEC (1:1, v/v) it is provided in electrolyte
700mAh g-1Specific capacity.C.Lai etc. first calcines 6 hours then 300 at 150 DEG C after polyacrylonitrile is blended with elemental sulfur
DEG C continue calcining 3 hours, the mass fraction for obtaining sulphur in S-containing composite is 57%, in 1M LiPF6PC/EC/DEC (1:
4:5, v/v/v) very stable cycle performance is provided in electrolyte, is stablized in 745mAh g-1.Shuya Wei etc. is by polypropylene
Nitrile and elemental sulfur are blended in 400 DEG C of calcinings, and the mass fraction of sulphur is 45.6% in obtained S-containing composite, in 1M LiPF6
EC/DEC (1:1, v/v) stable cycle performance is obtained in electrolyte, capacity remains at after 0.4C runs 1000 circulations
1000mAh g-1More than.
Meanwhile restrict the practical application of lithium-sulfur cell there are one factor, i.e. lithium anode bring safety is hidden
Suffer from.Traditional commerce electrolyte is to conduct ion by small molecule lithium salts, can be rich in fact, anion and be not involved in electrode reaction
Collection causes concentration polarization, and then lead to the formation of dendrite in electrode surface.
