Generation lithium ion battery is so-called " all-solid-state battery ", and flammable organic electrolyte is instead of using solid electrolyte, from basic
On solve the safety problem of battery, solid electrolyte diaphragm has also turned into current study hotspot.
In lithium rechargeable battery research process, be generally all be assembled into small-sized button cell with characterize electrode material and
The chemical property of battery.Equally, for " all-solid-state battery ", after preparing solid electrolyte diaphragm, generally every
The splash of film both sides attaches metal electrode, with Li7La3Zr2O12(LLZO) as a example by solid electrolyte diaphragm, test ion conductance
When, in LLZO barrier films both sides splash Au electrodes, Au | LLZO | Au interlayer structures are constituted, it is similar with button cell structure, then again
It is connected with test performance with electrochemical workstation counter electrode.
The test connecting-wire connector that conventional electrochemical workstation is provided is crocodile clip, does not have special button cell to survey
Examination fixture.And when carrying out button cell performance test using conventional copper folder, due to insufficient pressure, easily there is virtual connection, loose contact
Etc. phenomenon.
The content of the invention
The purpose of this utility model is to solve the problems, such as the loose contact that conventional button cell easily occurs in test process, is carried
For a kind of simple structure, contact closely, the button cell test fixture of pressure adjustable section.
The utility model solves the above problems the technical scheme of use：Pressurization button cell measuring clamp includes jig main body
1st, anode plate 2, negative plates 3, spring 4 and pressurization screw rod 5, the both sides of jig main body 1 are provided with pole plate drainage clamp bar slot a 6-
1st, pole plate drainage clamp bar slot b 6-2；During test, anode plate 2 is placed on the bottom of main body 1, and its drainage strip is stuck in jig main body 1
In pole plate drainage clamp bar slot a 6-1；The positive pole of button cell 7 down, is placed on anode plate 2；Negative plates 3 are placed on button
On battery 7, its drainage strip is stuck in the pole plate drainage clamp bar slot b 6-2 of jig main body 1；Spring 4 is placed in negative plates 3,
Pressed by the pressurization screw rod 5 on its top and fixed.
Jig main body 1 is the lucite or engineering plastics of insulation；Anode plate 2, negative plates 3 are conductive stainless steel
Or copper material.
It is 1000Pa~1MPa that pressurization screw rod 5 applies pressure limit to spring 4.
Regulation pressurization screw rod process can directly regulation pole plate and button cell between contact, it is ensured that pole plate with
Close contact between button-type battery electrode.During test, the crocodile clip of electrochemical workstation connecting line is clipped in respectively corresponding
On pole plate drainage strip.
Above-mentioned jig main body is the lucite or engineering plastics of insulation, and it is open circuit between button cell both positive and negative polarity to make；Just
Pole pole plate, negative plates are conductive stainless steel or copper material, draw the positive pole of button cell, cathodal current respectively during test
Go out.
The beneficial effects of the utility model：The pressurization button cell measuring clamp simple structure of offer, profit in test process
Pressed with pressurization screw compression spring button type battery, so as to ensure that electrode contact is tight, it is to avoid the appearance of virtual connection phenomenon, greatly
The big reliability that improve in Electrochemical Test Procedure, is particularly suitable as the solid electricity of button cell and both sides splash electrode layer
The electrochemical property test fixture of solution matter barrier film etc. is used.

Specific embodiment
Embodiment 1
Jig main body 1 is lucite, and anode plate 2, negative plates 3 are copper material.During assembling, anode plate 2 is placed
In the bottom of jig main body 1, its drainage strip is stuck in pole plate drainage clamp bar slot a 6-1；Au | LLZO | Au interlayer structures are placed
On anode plate 2, the Au electrodes on the downside of Au | LLZO | Au are contacted with anode plate 2；Negative plates 3 are placed on Au | LLZO | Au
On, its drainage strip is stuck in pole plate drainage clamp bar slot b 6-2, the Au electrode contacts on the upside of negative plates 3 and Au | LLZO | Au；Bullet
Spring 4 is placed in negative plates 3, is pressed by the pressurization screw rod 5 on its top and fixed；The process of regulation pressurization screw rod 5 can be straight
The contact between regulation pole plate and Au | LLZO | Au is connect, pressure is 0.05MPa, it is ensured that tight between pole plate and Au electrodes
Contact.During test, the crocodile clip of electrochemical workstation connecting line is clipped on corresponding pole plate drainage strip respectively.For same
LLZO barrier film samples：When being tested as fixture using ordinary copper folder, it is 4.22 × 10 to obtain sample ions electrical conductivity-5S/cm；Adopt
During with pressurization button battery clamp, sample ions electrical conductivity is 6.91 × 10-5S/cm, electrical conductivity test result has obtained substantially carrying
Height, illustrates that the contact resistance between sample and test fixture is substantially reduced.
Using the utility model proposes pressurization button cell measuring clamp significantly improve contact between electrode, effectively keep away
Exempt from the generation of virtual connection phenomenon, be particularly suitable for Au | LLZO | Au interlayer structures and button cell be connected with electrochemical workstation into
Row performance test.
