Abstract
The utility model provides a lithium battery comprising a casing and a battery cell arranged in the casing. Electrolyte is filled between the casing and the battery cell, leads of a positive electrode and a negative electrode of the battery cell are led out from an opening of the casing, the opening of the casing is closed by sealant, and a conductive rubber adhesive layer is paved on the surface of the inner side of the sealant. The lithium battery is simple in structure and low in cost. Production efficiency is improved. Meanwhile, the conductive adhesive layer is provided with penetration holes or electrolyte injection holes, and safety of the lithium battery is improved as well.
Description
Technical field
The utility model relates to the battery technology field, is a kind of lithium battery specifically.
Background technology
Lithium ion battery is a kind of big capacity, high-power battery, and it is mainly used on the mini-plant, particularly mobile phone, laptop computer, portable power tool.In its manufacture process, the electric core that finishes of reeling need be fixed with gummed paper Song.
Generally use four gummed papers to fix at present in the industry, lay respectively between the positive and negative lug on electric core top, electric core bottom and electric core the right and left, promptly four gummed papers lay respectively at electric core four limits.Because gummed paper sticks on four limits of electric core, influenced that pole piece causes fluid injection not reach technologic fluid injection critical field to the infiltration rate of electrolyte in the electric core, and increased the digestion time after the electric core fluid injection.Cause the defective products rate of battery to improve, and extended the production cycle, increased production cost.
The utility model content
The technical problem that the utility model will solve is: a kind of lithium battery is provided, and its electric core enclosuring structure is simple, reliable, and safe in utilization.
In order to solve the problems of the technologies described above; The utility model adopts following technical scheme: a kind of lithium battery, and comprise housing, be arranged on the electric core in the housing, between housing and electric core, electrolyte is housed; The both positive and negative polarity lead of electricity core is drawn from the opening part of housing; Wherein, adopt the opening part sealing of fluid sealant, be laid with conductive adhesive layer at the inner surface of said fluid sealant with housing.
In described lithium battery, be preferably, said conductive adhesive layer is provided with permeability hole.
In described lithium battery, be preferably, said conductive adhesive layer is provided with liquid injection hole.
The described lithium battery of the utility model comprises housing, is arranged on the electric core in the housing, and the both positive and negative polarity lead of electric core is drawn from the opening part of housing, adopts the opening part sealing of fluid sealant with housing, is laid with conductive adhesive layer at the inner surface of said fluid sealant.It is simple in structure, and cost is low, has also improved production efficiency.Said electric glue-line is provided with permeability hole or liquid injection hole simultaneously, has also improved its fail safe.
Description of drawings
Fig. 1 is the structural representation of the said lithium battery of the utility model.
Embodiment
Below combine accompanying drawing that the utility model is made more detailed description with embodiment.Present embodiment only is the description to the utility model preferred forms, and the scope to the utility model does not have any restriction.
Embodiment
As shown in the figure; Said lithium battery; Comprise housing 1, be arranged on the electric core 2 in the housing 1, between housing 1 and electric core 2, electrolyte 6 is housed, the both positive and negative polarity lead 5 of electric core 2 is drawn from the opening part of housing 1; Adopt the opening part sealing of fluid sealant 3, be laid with conductive adhesive layer 4 at the inner surface of said fluid sealant 3 with housing 1.Said both positive and negative polarity lead 5 can be arranged on an end of housing 1, also can be arranged on the two ends of housing 1.Said fluid sealant 3 has improved the cohesive force of electric core 2 and housing effectively, makes electric core enclosuring structure simple, reliable.
Preferably, said conductive adhesive layer 4 is provided with permeability hole and/or liquid injection hole.Permeability hole has been accelerated the seepage velocity of electrolyte, makes the speeding up of conductive adhesive layer 4 Electolyte-absorptives; Through being set, liquid injection hole make fluid injection very reach the technological standards scope easily; Reduced the digestion time of electric core after the fluid injection; Shortened the production cycle of battery; Reduced the defective products rate of electric core; Improved its fail safe of battery.
