Description

A kind of preparation technology of all solid lithium sulphur cell positive electrode
Art
The present invention is a kind of all solid lithium sulphur cell positive electrode " ion-electron hybrid conductive electrode " preparation technology, electrode is the major part of storage battery, as energy storage device, storage battery is widely used in the energy, traffic, Aeronautics and Astronautics, industry, electronics, the multiple field of electrical equipment.
Technical background
Current people storage battery used is substantially all liquid electrolyte, and security performance is not high, needs to improve, and all solid state electrolyte is a desirable selection; Meanwhile, existing storage battery specific capacity is also less than normal, and hinder Development of Electric Vehicles, lithium sulfur system has very high specific capacity, becomes the focus of each scientific research institution research.But lithium sulfur system storage battery cycle performance is not good is stranded its commercialization always, the not good reason of lithium-sulfur cell cycle performance mainly: non-conductive, the many sulphion of elemental sulfur is dissolved in liquid electrolyte, sulfur particle occurs to reunite and reaction time change in volume large.In order to address these problems, people have employed multiple method: sulphur carbon compound, sulphur and polymer compound, sulphur metallizing thing compound etc., achieve good progress, but still have gap from real requirement! The novel storage battery of height ratio capacity and high safety performance becomes a kind of exigence.
Summary of the invention
The present invention is a kind of for all solid lithium sulphur cell positive electrode " ion-electron hybrid conductive electrode " preparation technology.
Current storage battery is made up of active material, conductive agent, binding agent three part due to its electrode, electrode only has electron conduction, and substantially there is no ionic conductivity, when adopting all solid state electrolyte, lithium ion cannot transmit in electrode interior, electrode and electrolytical interface impedance are also difficult to solve, and all solid state lithium-sulfur cell cannot reach commercial level always.
" ion-electron hybrid conductive electrode " of the present invention be exactly in order to: 1, overcome elemental sulfur change in volume when reacting large, dissolve, reunite, the problem such as conduction difference; 2, all solid state lithium-sulfur cell can all-round developing and application.
The technical problem solved
1, the problems such as height ratio capacity electrode active material sulphur change in volume when reacting is large, dissolving, reunion, conduction difference are overcome; 2, the development in an all-round way of all solid state lithium-sulfur cell and application how is realized.
Technical scheme
The present invention's " ion-electron hybrid conductive electrode " preparation technology, concrete scheme is: 1, elemental sulfur and carbon carry out hot compound, obtain sulphur carbon composite; 2, by sulphur carbon composite and conductive agent, binding agent and compound all solid state organic polymer electrolyte compound, to be coated with carbon aluminium foil or Graphene coated aluminum foil for collector, formed " ion-electron hybrid conductive electrode ", namely all solid lithium sulphur cell composite anode.
Beneficial effect
The present invention is applicable to the application of total solids lithium-sulfur cell very much, for the practicality of all solid state lithium-sulfur cell provides solution.
