Abstract
The utility model relates to a lithium battery, specifically relating to a lithium battery that is capable of rapidly absorbing injected liquid and the ageing time is short. The utility model discloses a lithium battery, comprising a casing, electrolyte and an electric core cell consisting of a positive and a negative pole pieces and diaphragm paper. At least one end where the electric core unit is perpendicular to the winding direction is stuck with glue paper, and the glue paper is arranged with penetrating holes. The utility model solves the problem that the injected liquid is not able to reach standard range of the injected liquid due to slow absorption, and effectively shortens ageing time after being injected liquid, as well as shortens production cycle of the battery; hence the utility model is beneficial to popularization in industrial production.
Description
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.
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 and negative plate and diaphragm paper post gummed paper at electric core unit perpendicular at least one end of its coiling direction, also are provided with permeability hole on the gummed paper.
Described lithium battery wherein posts gummed paper at electric core unit perpendicular to the upper end of its coiling direction.
Described lithium battery wherein posts gummed paper at electric core unit perpendicular to the lower end of its coiling direction.
Described lithium battery wherein all posts gummed paper at electric core unit perpendicular to the two ends up and down of its coiling direction.
Described lithium battery, wherein above-mentioned gummed paper is provided with 12 permeability holes.
Described lithium battery, wherein above-mentioned gummed paper is provided with 24 permeability holes.
Described lithium battery, wherein the diameter of above-mentioned permeability hole is 1mm.
Described lithium battery, wherein above-mentioned gummed paper is a silica gel paper.
Beneficial effect of the present invention, 1) owing to have permeability hole on the gummed paper, 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) simple to operate, control helps the popularization of suitability for industrialized production easily.
