Abstract
The invention belongs to a preparing method of an adhesive film for edges of electrodes, which is characterized by comprising the following preparing processes: 1) preparing adhesive: pouring anhydrous ethyl alcohol into a container, adding PVB while agitating and then uniformly agitating, sealing and laying the container up over 12 hours, thereby forming liquid cement, 2) dipping the liquid cement: taking the liquid cement to dilute with anhydrous ethyl alcohol, then dipping and coating the mixed liquid cement onto the edge of an electrode plate, 3) scraping edges: utilizing a stainless steel sheet to flatten the four flanges of the electrode plate, and the edges of the electrode plate are dipped with the liquid cement, thereby forming an adhesive film layer at the edges of the electrode plate after drying. By dipping and coating the liquid cement with fine permeability and adhesiveness on the edges of the electrode, active substance particles can be caught, thereby forming an adhesive film, which is not only simple in structure but can effectively prevent battery short circuit caused by powder-off and burr on the edges of the electrode. Further, because the adhesive film is extremely thin, the thickness and volume of the edges of the electrode can not be increased, and influence on ion breakthrough are avoided, thereby preventing damages to battery performances and increasing battery properties.
Description
Technical field
The invention belongs to alkali secondary cell mounting technology field, particularly relate to a kind of glue film manufacturing process for electrode rim.
Background technology
At present, in the cell Assembling Production process, because electrode rim shedding or edge burr cause battery short circuit, the general method that plastics adhesive sticker bar is bonded at electrode rim that adopts; The method of this stickup adhesive tape be to guarantee adhesive tape paste operation intensity except pasting difficulty, adhesive tape should not be too thin, certainly will increase thickness of electrode like this, major diameter garden cylindrical battery particularly, and the length of electrode is longer; Big capacity rectangular cell, pole piece is more, not only increases the useless volume of battery, also can influence battery performance.
Summary of the invention
The present invention is for solving problems of the prior art, and provides simple to operate, prevents because the battery short circuit that electrode rim shedding and electrode rim burr cause, and improves a kind of glue film manufacturing process for electrode rim of battery performance.
The present invention for solving the technical scheme that technical problem adopted that exists in the known technology is:
Glue film manufacturing process for electrode rim is characterized in: comprise following preparation process:
1) join glue:
Absolute ethyl alcohol is poured in the container, and stirring continues to stir after adding PVB, and seal of vessel was shelved more than 12 hours, forms glue;
2) dip in glue:
Get above-mentioned glue, again with absolute ethyl alcohol dilution, with the glue dipping of configuration on the pole piece edge.
3) scrape the limit:
With stainless steel substrates that the edge, four limits that the pole piece edge dips in glue is floating, after drying, the pole piece edge forms one deck glued membrane.
The present invention can also adopt following technical measures to realize:
Glue film manufacturing process for electrode rim is characterized in: join described 1) that absolute ethyl alcohol is 1000ml in the glue; Described is airtight container; Described stirring is for slowly stirring; Described PVB is 60g, seal of vessel is set aside to PVB dissolve fully, does not have bubble in glue.
Glue film manufacturing process for electrode rim is characterized in: the ratio of glue and absolute ethyl alcohol dilution is 1:1 described 2).
Glue film manufacturing process for electrode rim is characterized in: stainless steel substrates is smooth radian shape described 3).
Glue film manufacturing process for electrode rim is characterized in: the glued membrane utmost point size that the pole piece edge forms described 3) is generally 1-3mm.
Advantage and good effect that the present invention has are: because adopt a kind of permeability and adhere to viscosity all glue dipping preferably on electrode rim, catch active material particle, form a kind of glued membrane, not only easy and simple to handle, effectively prevent electrode rim shedding and the battery short circuit that causes with burr, because glued membrane is than book, electrode rim increases thickness hardly, do not account for volume, do not influence ion penetration, thereby do not damage battery performance.Improved battery performance.
Embodiment
For further understanding summary of the invention of the present invention, characteristics and effect, enumerate following examples now, be described in detail as follows: configuration is used for the glue of dipping electrode rim, and specific operation process is as follows:
1) join glue:
The 1000ml absolute ethyl alcohol is poured in the resealable container, slowly added 60g PVB under stirring, stir, seal of vessel was shelved more than 12 hours, treat that PVB dissolves fully, in glue, do not have bubble;
2) dip in glue:
Get above-mentioned glue, in the 1:1 ratio, with after the absolute ethyl alcohol dilution, with the glue dipping of configuration on the pole piece edge.
3) scrape the limit:
With band radian and smooth stainless steel substrates that the edge, four limits that the pole piece edge dips in glue is floating, dry into glued membrane, the pole piece edge dips in the glued membrane height that liquid forms and is generally 1-3mm according to electrode size.
Claims (5)
