Abstract

The utility model relates to a lithium battery, in particular to a lithium ion battery which can absorb the injected liquid quickly and need short ageing time. The utility model comprises an outer shell, electrolyte, a positive polar plate, a negative polar plate and an electric core element made of convoluted separator paper. A filtering hole is arranged on the positive and negative polar plates in the electric core element. The utility model solves the problem that injected liquid can not come up to the standard because of slow absorption. And ageing time of the electric core after liquid injection is effectively shortened. Thus the production period of battery is shortened, which is good for industrial production extension and improves cycling performance of battery.

Description

A kind of lithium battery
Technical field
The present invention relates to a kind of lithium battery, be specifically related to a kind of can the fast Absorption fluid injection and the short lithium ion battery of digestion time.
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 fix with gummed paper.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.
Summary of the invention
The purpose of this invention is to provide can fast Absorption fluid injection and the short lithium ion battery of digestion time.The invention solves fluid injection and absorb slow and cause fluid injection not reach the problem of technologic fluid injection critical field, and shortened the digestion time of electric core after the fluid injection effectively, and improved the cycle performance of battery.
Technical scheme of the present invention: a kind of lithium battery, comprise shell, electrolyte and the electric core unit that is wound into by positive plate, negative plate and diaphragm paper, the positive plate in the electric core unit is or/and negative plate is provided with permeability hole.
Described lithium battery wherein posts the gummed paper that is provided with permeability hole at electric core unit perpendicular at least one end of its coiling direction.
Described lithium battery wherein posts the gummed paper that is provided with permeability hole at electric core unit perpendicular to the upper end of its coiling direction.
Described lithium battery wherein posts the gummed paper that is provided with permeability hole at electric core unit perpendicular to the lower end of its coiling direction.
Described lithium battery wherein all posts the gummed paper that is provided with permeability hole at electric core unit perpendicular to the two ends up and down of its coiling direction.
Described lithium battery, the diameter that wherein reaches the permeability hole that is provided with on the above-mentioned gummed paper on the positive/negative plate is 1mm.
Described lithium battery, wherein the permeability hole that is provided with on the positive/negative plate is irregular distribution.
Beneficial effect of the present invention, 1) because the positive/negative plate in the electric core unit is provided with permeability hole, accelerates the seepage velocity of electrolyte, made the speeding up of electric core pole piece Electolyte-absorptive; 2) make the very easy technological standards scope that reaches of fluid injection; 3) reduced the digestion time of electric core after the fluid injection; 4) shortened production cycle of battery; 5) reduced the defective products rate of electric core; 6) improved the cycle performance of battery; 7 is simple to operate, and control helps the popularization of suitability for industrialized production easily.
