Abstract
A kind of method for judging lithium ion battery glue dispersion effect, comprises the following steps：（1）Prepare positive and negative anodes glue；（2）A certain amount of glue is taken to beat slowly and into wide-mouth bottle and is sealed room temperature preservation, stand 24~48 it is small when, test and gelatin viscosity and recorded when 4 is small；（3）With infrared lamp light through wide-mouth bottle glue, go out from the vertical direction of incident light in wide-mouth bottle glue whether one existing bright " access "；（4）Glue is divided into 10~20 parts to other containers and tests solid content, makes solid content distribution map.Present invention has the advantages that by the way that glue, the solid content of different position, Tyndall phenomenon and viscosity three broad aspects that change with time determine the dispersion effect of positive and negative electrode glue and provide a kind of method of simple possible in stirring container, and this method is simple, device simple is simultaneously effective, it is easy to operate, quickly glue dispersion effect can be judged.
Description
Technical field
The invention mainly relates to technical field of lithium ion, disperse more particularly, to a kind of judgement lithium ion battery glue
The method of effect.
Background technology
Lithium ion battery has operating voltage high, and higher than energy, capacity is big, and self discharge is small, good cycle, service life
It is long, it is light-weight the advantages that, have become the light-weighted critical energy component of electric vehicle, be the representative of modern high performance battery,
It is the major impetus source of the ideal source of the portable electric appts such as mobile phone, laptop, cordless power tool etc.
One of.For lithium ion battery production, the preparation of glue is crucial first of battery production before anode and cathode slurry is prepared
Process directly affects electrode and battery quality and performance, such as battery capacity, the uniformity of internal resistance, the quality of cycle performance etc..
In order to ensure the quality of lithium ion battery, it is of great significance to good and bad judge of its positive and negative anodes glue quality.
The content of the invention
The present invention be directed to above-mentioned backgrounds to propose a kind of method for judging lithium ion battery glue dispersion effect, and purpose exists
Judge lithium ion battery plus-negative plate glue dispersion effect quality method in providing, the quality for improving lithium ion battery is consistent with battery
Property.
The technical solution adopted by the present invention is：
A kind of method for judging lithium ion battery glue dispersion effect, specifically includes following steps：
（1）According to itself company's system formulation proportion requirement, positive and negative anodes glue is prepared using a mixing bowl；
（2）From a mixing bowl just prepared glue, take a certain amount of glue beat slowly into wide-mouth bottle and be sealed room temperature guarantor
It deposits, when standing 24~48 is small（The common preservation usage time of battery industry glue）, gelatin viscosity is tested when 4 is small and is carried out
Whether record, see the viscosity within the production time in the range of technique mark；
（3）With infrared lamp light through wide-mouth bottle glue, go out from the vertical direction of incident light in wide-mouth bottle glue whether
One existing bright " access ", have " access " glue is then colloid, represents to be uniformly dispersed, does not have the glue of " access " then
For solution, scattered unevenness is represented；
（4）The glue of a mixing bowl is divided into 10~20 parts to other containers and tests solid content, makes solid content distribution map,
Solid content is scattered more uniform closer to representing.Since when glue is uniformly dispersed, the glue in a mixing bowl different position, i.e. average mark
It should be consistent to the glue solid content of other containers into several pieces.
The beneficial effects of the present invention are：By the way that glue, the solid content of different position, dindar are existing in stirring container
As and viscosity three broad aspects that change with time determine the dispersion effect of positive and negative electrode glue and provide a kind of side of simple possible
Method, and detection method is simple, device simple is simultaneously effective, easy to operate, and quickly glue dispersion effect can be sentenced
It is fixed, excessive glue is avoided to prepare waste and glue Quality Detection waste of time of mixing time etc..
Description of the drawings
Fig. 1 is trend chart when gelatin viscosity 48 is small.
Fig. 2 is " access " schematic diagram that infrared ray tests glue.
Fig. 3 is that the glue of a mixing bowl is divided into the solid content schematic diagram tested after 20 parts of parts.
