Abstract
A kind of battery formation clamp of flexible package lithium cell provided by the utility model, including the front plate and rear plate being bolted, the inside middle portion of the front plate is provided with pressure sensor, outside is provided with display, and the pressure sensor is connected with display by signal wire.Pressure between forward and backward clamping plate is adjusted according to pressure size, so as to control the contact between pole piece and barrier film, pressure size during to formation of Li-ion batteries, partial volume and loop test provides numerically modeling.
Description
Technical field
It the utility model is related to field of lithium ion battery, and in particular to a kind of battery formation clamp of flexible package lithium cell.
Background technology
Flexible packing lithium ion battery, as shell, the advantage is that, its size and thickness can be according to designs using aluminum plastic film
It is required that and change, but plastic-aluminum film hardness is low compared with aluminum hull, easily deforms, the control of outward appearance relative difficult.And existing plate body
Clamp method is applied to the limited strength on battery surface, easily causes discontinuity in soft bag lithium ionic cell plane, electricity
There can not be enough pressure in the middle part of pond, contact effect of the soft bag lithium ionic cell subregion positive and negative plate with barrier film can be influenceed,
Gas discharge during so as to influence the formation of SEI films and soft bag lithium ionic cell forming and capacity dividing.
The conventional aluminum hull of battery is as shell, its battery core uniform force inside aluminum hull, be subsequently melted into battery core, partial volume and
A good pressure effect can be given during circulation etc. to battery core, ensures the close contact between both positive and negative polarity and barrier film,
Contact internal resistance to battery has a good restriction effect；And aluminum plastic film can effectively reduce the matter of battery as battery case
Amount, has a distinct increment to the energy density of battery.
Aluminum-shell battery in cyclic process because the factors such as internal aerogenesis can cause aluminum hull forced expansion, between pole piece and barrier film
Contact is deteriorated, and when due to aerogenesis causes internal pressure to reach much when can significantly affect cycle performance this problem can not be fine
Solution.
Utility model content
In view of this, the purpose of this patent is to provide a kind of battery formation clamp of flexible package lithium cell, can uniformly apply pressure
Power, and a kind of device controllable to pressure size, and being quantized to pressure size.
In order to reach above-mentioned purpose, a kind of battery formation clamp of flexible package lithium cell provided by the utility model, including pass through
Bolted front plate and rear plate, the inside middle portion of the front plate is provided with pressure sensor, outside is provided with display
Device, the pressure sensor are connected with display by signal wire.
Further scheme, the inner side of the front plate and rear plate are symmetrically offered for the recessed of placing battery lug on one side
Groove.
Further scheme, bolt hole is offered at the corner of the front plate and rear plate.
Flexible package lithium cell when in use, is first placed on the centre of forward and backward clamping plate by the present apparatus, makes battery pole ear positioned at recessed
In groove；Forward and backward clamping plate is connected by bolt again, the pressure sensor on the inside of front plate contacted with lithium battery and
Pressure data is produced, and passes on display and shows by signal wire.Screwed according to the pressure data on display
Or bolt is unscrewed, so as to control the contact in battery between both positive and negative polarity and barrier film, so that soft-package battery is in chemical conversion, partial volume
The research of effect is contacted with both positive and negative polarity pole piece with loop test septation.
Brief description of the drawings
Fig. 1 is front view of the present utility model,
Fig. 2 is the rearview of the front plate in the utility model,
Fig. 3 is side view of the present utility model.
In figure：1- bolts hole, 2- displays, 3- front plates, 4- grooves, 5- pressure sensors, 6- bolts, 7- rear plates.
Embodiment
As Figure 1-3, a kind of battery formation clamp of flexible package lithium cell, including by the front plate 3 that bolt 6 connects with after
Clamping plate 7, the inside middle portion of the front plate 3 is provided with pressure sensor 5, outside is provided with display 2, the pressure sensor
5 are connected with display 2 by signal wire.
Further scheme, the inner side of the front plate 3 and rear plate 7 are symmetrically offered for placing battery lug on one side
Groove 4.
Further scheme, bolt hole 1 is offered at the corner of the front plate 3 and rear plate 7.
Flexible package lithium cell when in use, is first placed on the centre of forward and backward clamping plate by the present apparatus, makes battery pole ear positioned at recessed
In groove；Forward and backward flat board is connected after bolt to be passed through to the bolt hole on forward and backward clamping plate again, on the inside of front plate
Pressure sensor contacts with lithium battery and produces pressure data, and passes on display and show by signal wire.According to
Pressure data on display screws or unscrewed bolt, so as to control the contact in battery between both positive and negative polarity and barrier film,
So that soft-package battery contacts in chemical conversion, partial volume and loop test septation the research of effect with both positive and negative polarity pole piece.
This fixture operation is simple, and pressure size during to formation of Li-ion batteries, partial volume and loop test provides numerically modeling, right
Contact force research between the pole piece and barrier film of lithium battery has certain indicative function.
Above content is only the embodiment made to the utility model structure, is not used for limiting its practical range：I.e.
All modifications made according to described specific embodiment or supplement are substituted using similar mode, all should belong to the utility model
Right.
