Abstract
The present invention discloses an injection method for battery electrolyte. The method comprises the following steps that: firstly a forceps is adopted to nip a battery cover cap; the battery cover cap is relied on a side position of a battery housing open; a tip of a syringe is close to a side of a positive electrode lug, and is slowly inserted in an electrical core center hole, wherein the height of the end of the inserted tip is the 2/3 height of the whole height of the electrical core; electrolyte is injected in the syringe, wherein the liquid level of the electrolyte does not excess the battery housing open; after the electrolyte is completed absorbed by the electrical core, the above steps are repeated until the total amount of the absorbed electrolyte meets the requirement; a rubber pipette bulb is adopted to blow air to the syringe; then the tip is slowly pulled out from the electrical core; the positive electrode lug is folded; the battery cover cap is flatly pressed into the battery housing open; finally the battery is sealed. With the injection method for the battery electrolyte, the electrolyte can be uniformly absorbed by each part of the electrical core; the performance consistencies among the single batteries can be greatly improved; the steel housing can be prevented from corrosion and rust; the appearance of the battery can be maintained.
Description
Technical field
The present invention relates to a kind of method for implanting of battery electrolyte.
Background technology
Cylindrical lithium ion battery adopts sleeve fluid injection mode, is disposable required electrolyte directly to be injected in the sleeve, and electrolyte from top to bottom flows into electric in-core; The electricity core from top to bottom absorbs electrolyte, owing to there is air pressure to exist in the battery, causes electrolyte flow rate very slow; Also make electric core that Electolyte-absorptive is extremely inhomogeneous everywhere; Reservoir quantity is unstable, causes the actual liquid absorption consistency of electric core poor, directly influences the performance difference between cell.Adopt sleeve fluid injection mode simultaneously, have corrosive electrolyte and overflow from interface easily, thereby the corrosion box hat has a strong impact on the battery outward appearance.
Summary of the invention
The technical problem that the present invention will solve provides a kind of method for implanting of battery electrolyte, and electrolyte is evenly distributed, and keeps battery quality stable and specious.
In order to solve the problems of the technologies described above, the method for implanting of a kind of battery electrolyte of the present invention may further comprise the steps:
S1. live battery cap with the tweezers tweezer, battery cap is relied on the position to the battery case opening on one side, outstanding electric core central hole location;
S2. with the needle point of syringe near positive pole ear one side, slowly be inserted in the electric core centre bore, the position of the needle point end of insertion is in 2/3 place of whole electric core height;
S3. use infusion pump in syringe, to inject electrolyte, liquid level of electrolyte is no more than the battery case opening part, treat the complete Electolyte-absorptive of electric core after, repeat above-mentioned steps, till total liquid absorption of electric core meets the requirements;
S4. use rubber pipette bulb in syringe, to blow, then needle point is slowly extracted out from electric in-core, folding positive pole ear is entirely compressed into the battery case opening with battery cap, at last with battery seal.
As the improvement of technique scheme, said needle point is through slick and sly processed.In the S3 step, processing is left standstill or vacuumized to completion to electric core after injecting electrolyte.
The invention has the beneficial effects as follows: the mode that the method for implanting of this battery electrolyte adopts needle point to inject electrolyte in electric in-core portion can guarantee the even absorption of each position of electric core to electrolyte; Greatly improve the consistency of the performance between cell; And avoid box hat to receive rust corrosion; Both guarantee battery quality, effectively improved the battery efficiency of assembling, and kept battery specious again.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is done further detailed explanation.
Fig. 1 is an operation chart of the present invention;
Fig. 2 is the structural representation of battery cap.
Embodiment
With reference to Fig. 1, Fig. 2, the method for implanting of a kind of battery electrolyte of the present invention may further comprise the steps:
S1. live battery cap 1 with the tweezers tweezer, battery cap 1 is relied on the position to battery case opening 2 on one side, outstanding electric core centre bore 3 positions;
S2. with the needle point 5 of syringe 4 near positive pole ear 6 one sides, slowly be inserted in the electric core centre bore 3, the position of the needle point end of insertion is in 2/3 place of whole electric core height, guarantees that electrolyte from bottom to top is absorbed;
S3. use infusion pump in syringe 4, to inject electrolyte, liquid level of electrolyte is no more than battery case opening 2 places, avoids electrolyte to overflow; Influence the uniformity and pollution box hat of reservoir quantity; After treating the complete Electolyte-absorptive of electric core, repeat above-mentioned steps, till total liquid absorption of electric core meets the requirements;
S4. use rubber pipette bulb in syringe 4, to blow, then needle point 5 is slowly extracted out from electric in-core, folding positive pole ear is entirely compressed into battery case opening 2 with battery cap 1, at last with battery seal.
The mode that the method for implanting of this battery electrolyte adopts needle point to inject electrolyte in electric in-core portion can guarantee the even absorption of each position of electric core to electrolyte; Greatly improve the consistency of the performance between cell; And avoid box hat to receive rust corrosion; Both guarantee battery quality, effectively improved the battery efficiency of assembling, and kept battery specious again.
In the present embodiment, said needle point had both guaranteed through slick and sly processed that needle point can insert and can not pierce through pole piece and barrier film through electric core centre bore smoothly, guaranteed to inject the interior electrolyte of syringe again and can flow into electric core through needle point apace.
In the S3 step, processing is left standstill or vacuumized to completion to electric core after injecting electrolyte, guarantees that electric core absorbs electrolyte fully.
The above is merely preferential execution mode of the present invention, as long as realize that with basic identical means the technical scheme of the object of the invention all belongs within protection scope of the present invention.
