Description
Technical field
The invention belongs to set of cells packing technique field, relate to lithium ion battery, be specifically related to a kind of lithium-ion button battery
Assemble method.
Background technology
Lithium-ion button battery, owing to volume is little, low cost, assembles simple and convenient, is widely adopted as lithium ion battery
The primary evaluation means of material.The button cell shell mould number that Ge great universities and colleges and institute are commonly used at present have CR2016, CR2025,
CR2032, the assembling sequence of conventional lithium-ion button battery be followed successively by anode cover, positive plate, electrolyte, barrier film, electrolyte,
Negative pole lithium sheet, negative electrode casing, or order is the most contrary.This operating process is loaded down with trivial details, difficulty big, especially first on positive plate
Put barrier film again after dropping electrolyte and be easily caused barrier film adhesion, sideslip, add the time readjusting barrier film.It addition, treat every
Film is put and is also needed to drip once electrolytic liquid after just adding negative pole lithium sheet on lithium sheet again, and operation is loaded down with trivial details, time-consuming and qualification rate is low.
Summary of the invention
In order to solve the above-mentioned problems in the prior art, the mesh of the present invention is that offer one is easily operated, can have
Effect improves work efficiency and the lithium-ion button battery assemble method of qualification rate.
The present invention adopts the following technical scheme that a kind of lithium-ion button battery assemble method, and this lithium-ion button battery is pressed
Assembling sequence is followed successively by:
The first step: first put anode cover；
Second step: positive plate is put in anode cover middle；
3rd step: clip barrier film with tweezers and be put in gently directly over positive plate；
4th step: drip appropriate electrolyte from any one side of barrier film and make barrier film complete wetting；
5th step: the most suitably add some electrolyte in barrier film middle；
6th step: put on negative metal lithium sheet electrolyte directly over barrier film；
7th step: put nickel foam directly over negative metal lithium sheet；
8th step: the both sides clamping negative electrode casing with tweezers are anchored in nickel foam gently；
9th step: compress negative electrode casing with tweezers gently；
Tenth step: clamp the battery assembled with tweezers and its both sides are sealed.
Further, described positive plate is the pole piece of any positive electrode with aluminium foil as matrix.
Further, described barrier film is microporous polypropylene membrane.
Further, described nickel foam is in order to replace the current collector of routine, spring leaf.
Further, the electrolyte added in described 5th step is fully to infiltrate barrier film and negative metal lithium sheet.
The invention has the beneficial effects as follows: the assembling sequence of the present invention is followed successively by: first put anode cover；Positive plate is put in positive pole
Shell middle；Clip barrier film with tweezers to be put in gently directly over positive plate；Drip appropriate electrolyte from any one side of barrier film to make
Barrier film complete wetting；Some electrolyte are the most suitably added in barrier film middle；Put negative metal lithium sheet electricity directly over barrier film
Solve on liquid；Nickel foam is put directly over lithium sheet；The both sides clamping negative electrode casing with tweezers are anchored in nickel foam gently；With tweezers gently
Compress negative electrode casing；Clamp with tweezers and assemble the both sides of battery and seal.The battery using the inventive method to assemble has only to
Electrolyte is once added by barrier film enough, decrease on positive plate and negative metal lithium sheet, drip the secondary of electrolyte for twice
Number, can make positive plate and barrier film in button batteries process of assembling be centered at the most easily in anode cover.Avoid simultaneously and first exist
On positive plate drip electrolyte put barrier film again thus cause the easy adhesion of barrier film, the phenomenon of easy sideslip, shorten assembled battery
Time, the assembling of button cell can be completed fast and efficiently, decrease useless, the generation of substandard products, beneficially lithium ion battery are qualified
The lifting of rate, improves work efficiency.
Accompanying drawing explanation
Fig. 1. it is the assembling sequence figure of lithium-ion button battery of the present invention.
In figure: 1 anode cover, 2 positive plates, 3 barrier films, 4 electrolyte, 5 negative metal lithium sheets, 6 nickel foam, 7 negative electrode casings.
Detailed description of the invention
In conjunction with accompanying drawing, the present invention is described in further details.The technology that the present invention provides is followed successively by positive pole by assembling sequence
Shell 1, positive plate 2, barrier film 3, electrolyte 4, negative metal lithium sheet 5, nickel foam 6, negative electrode casing 7.The first step first puts anode cover 1；The
Two steps are that the side clamping positive plate 2 with tweezers gently is put in the middle of anode cover 1；3rd step tweezers clip barrier film 3 and put gently
Above positive plate 2；4th step drips appropriate electrolyte 4 from any one side of barrier film 3 and makes barrier film 3 complete wetting；5th step exists
Barrier film 3 middle adds an electrolyte 4 again；6th step puts negative metal lithium sheet 5 on the electrolyte 4 added, and makes negative pole gold
Belong to lithium sheet 5 align with positive plate 2 and fully infiltrate；7th step puts nickel foam 6 above negative metal lithium sheet 5, makes nickel foam 6 convex
Face down；8th step tweezers level is clamped the dual-side of negative electrode casing 7 and is placed on the surface of nickel foam 6 gently；9th step tweezer
Son compresses negative electrode casing 7 gently, makes anode cover 1, barrier film 3, negative metal lithium sheet 5, nickel foam 6, negative electrode casing 7 combine closely one
Rise, be difficult to disengage；Tenth step tweezers level is clamped and is assembled the both sides of anode shell 7 and seal.
Positive plate is the positive plate of any materials with aluminium foil as collector, and it can be very through barrier film after being infiltrated by electrolyte
Substantially being seen by naked eyes, beneficially aligning of negative metal lithium sheet is put together, improves the qualification rate of battery.Barrier film is capillary polypropylene
Film, can fully be infiltrated by electrolyte.Before dripping electrolyte at barrier film side can make barrier film moment be infiltrated, and electrolyte is put in holding
The position of positive plate, effectively prevents first dripping electrolyte and puts adhesion and the deviation phenomenon that barrier film brings again.The electrolyte added with
Can fully infiltrate barrier film to be advisable with lithium sheet, beneficially the abundant infiltration of both positive and negative polarity, makes the capacity maximum of active substance play.
