Description
Technical field
The invention belongs to lithium ion battery and its manufacturing fields, and in particular to a kind of solid electrolyte of the integration without interface
Lithium ion battery and preparation method thereof.
Background technology
Currently, traditional lithium ion battery generally use is toxic and the liquid organic electrolyte easily revealed, thus there are one
Fixed security risk and problem of environmental pollution.The poly-lithium battery that the nineties occurs uses the polymer of solid or gel state
Electrolyte, thus have higher security and stability and more excellent environment friendly.In addition, polymer Li-ion battery is also
With it is moulding flexibly, the advantages such as higher than energy, electrochemical stability window is wide, capacitance loss is few, volume utilization is high, be the following lithium
The main direction of development of ion battery.
But compared with it can be thoroughly impregnated the liquid electrolyte of electrode plates, polymer dielectric has solidity
Matter, conductibility of the lithium ion in solid electrolyte are far below liquid electrolyte；And polymer dielectric and electrode plates it
Between there is a problem of that closeness of contact is not good enough.In addition, the passivating film due to solid electrolyte is stablized relatively, so if used
The compatibility of solid electrolyte and electrode plates is poor will to be led to passivating film extension at any time and increases, to increase battery
Internal resistance.Therefore, it is to be badly in need of solving in the development of solid electrolyte lithium battery applications to improve the compatibility between electrode material and electrolyte
A key technical problem certainly.
For this technical bottleneck, researchers attempt to simplify the inside of lithium ion battery by constructing integral structure
Structure improves the contact condition of different inter-modules, and then improves the compatibility between battery component, reduces the interior of lithium ion battery
Resistance, to reach better energy-storage property.In the Chinese invention patent of Publication No. CN1219779A, researcher is to positive and negative electrode pole
Polyelectrolyte solution is perfused in the active material layer containing active material and binder of piece, polymer dielectric is made to permeate
Enter in anode and cathode active materials layer；Then solvent is evaporated, then the positive and negative electrode pole piece layer containing electrolyte is faced each other；Most
Afterwards, the two poles of the earth pole piece is heated by external hot solvent and forms platypelloid type solid electrolyte polymer lithium battery together.This method is logical
Infiltration of the electrolyte in electrode active material layers is crossed, the contact between electrolyte and active material is improved, reduces electricity
Pond internal resistance has obtained the lithium ion battery of excellent contact performance and high electric discharge output.The China of Publication No. CN103413966A
Patent of invention improves the compatibility of electrode material and anodic aluminium oxide membrane layer, and researcher will be with the nothing for infiltrating electrolyte
Machine ceramic particle is sprayed on electrode plates, and lithium ion battery membrane electrode is obtained through drying, rolling.Such membrane electrode piece is realized
Positive and negative electrode pole piece is integrated with isolation film, simplifies the structure of lithium ion battery, and gained lithium battery is shown better than passing
The high-temperature stability of system structure lithium ion battery.
However, in order to further decrease the internal resistance of cell, the solid state electrolysis that contact performance is excellent, electric discharge output performance is high is obtained
Matter lithium ion battery, it is still desirable to further increase between electrolyte and electrode active material it is compatible contact, make every effort to realization one
Solid electrolyte lithium ion battery of the body without interface.
Invention content
The technical purpose of the present invention is the state of the art for above-mentioned solid electrolyte lithium ion battery, provides a kind of solid-state
Electrolyte lithium-ion battery has the advantages that the internal resistance of cell is low, contact performance is excellent, specific discharge capacity is high, is a kind of one
Change the solid electrolyte lithium ion battery without interface.
The technical solution adopted in the present invention is：Solid electrolyte lithium ion battery of the integration without interface, including anode
Collector, the anode active material layer on plus plate current-collecting body, negative current collector, the anode active material layer on negative current collector,
And solid electrolyte, the anode active material layer include positive electrode active materials, conductive agent and binder, the cathode
Active material layer includes negative electrode active material, conductive agent and binder；It is characterized in that：In the binder and solid electrolyte
Including identical material component, that is, including following situation：
(1) when the binder and solid electrolyte are homogenous material, binder material and solid state electrolysis material
Expect identical；
(2) when the binder is combined material, and solid electrolyte is homogenous material, solid electrolyte material is viscous
Tie one kind in agent material；
(3) when the binder is combined material, and solid electrolyte is combined material, binder and solid electrolyte
In there are identical material components.
That is, the binders for electrodes in solid electrolyte lithium ion battery of the present invention is selected with solid electrolyte material
Same material, or make in the two there are identical material component, between the electrode and electrolyte to be conducive to improve battery
Compatibility improves conductivity of the lithium ion in charge and discharge process, reduces the internal resistance of cell, and can simplify battery and generate work
Skill improves the uniformity of electrode material layer, therefore in solid electrolyte field of lithium ion battery, especially high magnification, large capacity
It is with a wide range of applications in power solid electrolyte field of lithium ion battery.
In the present invention, the solid electrolyte material includes the polymeric material for having high ion-conductivity, high-adhesion
Material is advisable.Preferably, the solid electrolyte is fluorine-containing sulfimide base polymeric material, or contain fluorine-containing sulphonyl
The material of imido grpup polymers compositions contains fluorine-containing sulfonimide polymer group in the binder and solid electrolyte
Point, that is, including following situation：
(1) when the binder material and solid electrolyte material are homogenous material, binder material and solid-state
