Abstract
The invention belongs to the field of lithium ion batteries and particularly relates to a reusable lithium ion battery and a realization method thereof. The reusable lithium ion battery comprises a shell and a battery cell packaged in the shell, wherein a cavity is formed between the shell and the battery cell, is 1-3mm in width and is located above or below the battery cell or on the left or right of the battery cell. The realization method comprises the steps of: firstly, drilling an electrolyte injection port with the diameter of 0.5-2mm in the shell, corresponding to the cavity, and then injecting a certain quantity of electrolyte through the electrolyte injection port; and finally, sealing the electrolyte injection port with sealant. The invention develops a new way, and although the method is simple and convenient, an effect for recovering the capacity of the lithium ion battery is obvious.
Description
Technical field
The invention belongs to the lithium ion battery field, more particularly relate to a kind of lithium ion battery that reuses and implementation method.
Background technology
In some electronic products such as mobile phone, MP3, digital camera, battery is one of most important parts.When battery began to wear out, display voltage was normal basically when generally showing as zero load, and the battery electric quantity indication is basic to be full lattice, but stand-by time shortens; During charging, show promptly very soon that then battery is full of, but electric weight is exhausted soon.This moment, battery was declared to scrap basically, had also often determined the useful life of product its useful life simultaneously.
In order to address this problem; People all improve how battery capacity aspect work hard: same number of times, the same capability retention of charging and discharging; The capacity that battery kept that battery specific capacity capacious is little is more certainly, can make that battery operated useful life is able to prolong.But this method has great limitation: lightening is the development trend of battery; Battery can not ad infinitum increase; Can only under the prerequisite that does not increase volume, how to improve the energy density of battery, yet the production technology of this big capacity, high energy density cells there is not more breakthrough progress as yet at present.How but rarely has exploration under the condition of prior art, under the prerequisite that does not increase volume battery being had more to charge and discharge number of times.
And along with development of science and technology, the application of electronic product is more and more wider, and it is also more and more faster to update, and the contamination of products that thereupon brings increases the weight of day by day, and the pollution of old and useless battery has more harmfulness.Advocating the modern society of green science and technology, if can through little processing it is applied again, then can reduce pollution greatly to the battery that is about to scrap, realizing the regeneration of the energy, is the major issue of benefiting the nation and the people.And the present relevant report of not finding this respect as yet.
Summary of the invention
The object of the invention is to provide a kind of lithium ion battery and implementation method easy, that can reuse just.
To achieve these goals, the present invention adopts following technical scheme:
The lithium ion battery that can reuse; Comprise housing 1, be packaged in the electric core 2 in the housing 1; It is characterized in that being reserved with a cavity 3 between housing 1 and the electric core 2, the width L of described cavity 3 is 1-3mm, and described cavity 3 is positioned at top, below, left side or the right side of electric core 2.
Preferred scheme is in the liquid injection port 5 of housing 1 corresponding to a Φ 0.5-2mm of place reservation of cavity 3, can inject a certain amount of electrolyte and available fluid sealant 6 shutoff through this liquid injection port 5.
Also can corresponding to the place of cavity 3 a significantly sign 4 be set at housing 1.
Then further be optimized for the liquid injection port 5 of the Φ 0.5-2mm of sign 4 places reservation on housing 1, can inject a certain amount of electrolyte and available fluid sealant 6 shutoff through this liquid injection port 5.
When not reserving liquid injection port 5, the method for the lithium ion battery that realization can reuse may further comprise the steps:
At first in the liquid injection port 5 of housing 1 corresponding to the ground drill with ferrule Φ 0.5-2mm of cavity 3; Secondly inject a certain amount of electrolyte through liquid injection port 5; At last with fluid sealant 6 sealing liquid injection port 5.
The present invention is off the beaten track, and is though method is easy, obvious for the capacity of lithium ion battery recovery effects.With 454261 electric cores is example, in 0.5C life-span loop test, circulates 300 times the time, and capability retention is merely 70% [among Fig. 2 shown in the dotted line]; In the contrast test, circulate 300 times the time, capability retention is 85%, replenish electrolyte after, capability retention rises to 90%; And the circulation of electric core is during near 500 times, and capability retention is near 85% [among Fig. 2 shown in the solid line].
Description of drawings
Fig. 1 is the structural representation during electric core below for cavity of the present invention is positioned at;
Fig. 2 is effect contrast figure of the present invention.
Embodiment
With reference to Fig. 1.The electricity core is when encapsulation, at the inboard width of reserving 1.85mm of the effective packaging area of side.When electric core cycle performance can not satisfy instructions for use; The place that distinguishing mark is arranged being arranged in advance on the package film is used conelet or is drilled the liquid injection port of a diameter as 0.8mm for a short time; With syringe 0.75 milliliter non-aqueous electrolytic solution is injected wherein; After treating that electrolyte solution fully infiltrates, block liquid injection port with the fluid sealant that can assimilate film forming.The capacity of battery can return to nominal value about 80% after the fluid infusion.
It is understandable that, only provided the part execution mode of the flexible packing lithium ion battery of this invention novel package structure in this specification.According to above-mentioned principle, the present invention can also carry out suitable change and modification to above-mentioned embodiment.Therefore, the embodiment that discloses and describe above the present invention is not limited to also should fall into modifications more of the present invention and change in the protection range of claim of this patent.In addition, although used some specific terms in this specification, these terms are explanation for ease just, the present invention is not constituted any restriction.
