Abstract
The invention relates to the technical field of battery productions, and especially relates to a battery cover set. The battery cover set comprises an anode cover and an anode column. The outer surface of the anode column below the anode cover is provided with rough and uneven lines. According to the invention, with the rough and uneven lines arranged on the anode column, the contact area between the anode column and a carbon pack is increased, and the fluidity of lithium ions is effectively improved. Therefore, the reactions between the anode and the cathode are more sufficient, the discharge voltage is stable, and fluctuation is not occured.
Description
Technical field
The present invention relates to the battery production technical field, relate in particular to a kind of lid group of battery.
Background technology
At present, battery is complicated on production technology, and inhomogeneous if collector contacts with positive pole, the guiding discharge platform is unstable easily, and the heavy-current discharge capacity is low, and battery discharge procedure lost efficacy.This is because both positive and negative polarity reaction formation product is seen due to the contact-making surface of filling in collector and anodal carbon in the discharge process.
Current positive terminal all is smooth surface, is unfavorable for flowing of ion, the sluggish of both positive and negative polarity, and discharge capacity is little.
Summary of the invention
The present invention provides a kind of new lithium battery cap group to the problems referred to above.This battery cover group is simple in structure, the both positive and negative polarity reacting balance, and voltage is stable.
Technical scheme provided by the invention is:
A kind of battery cover group comprises positive cover and positive terminal, and the outer surface of the positive terminal of positive cover below is provided with scraggly lines.
Concrete, said scraggly lines is corrugated.
Concrete, said scraggly lines is latticed.
Concrete, positive cover is provided with liquid injection hole.
Concrete, positive terminal passes positive cover, and is fixed on the positive cover through vitreum.
Concrete, Vitrea upper surface is a horizontal plane.
Preferably, the positive cover upper surface is provided with a circle projection along excircle.
The present invention increases the contact area of positive terminal and carbon bag through scraggly lines is set on positive terminal, effectively improved the flowability of lithium ion.This makes that reaction is more abundant between the both positive and negative polarity, and discharge voltage is stable can not to produce fluctuation.Adopt now to add lines on the positive terminal and improve carbon and contact with positive terminal, strengthen battery discharge uniformity and heavy-current discharge platform, while sulphur that both positive and negative polarity produces and resting in the lines groove in discharge can not cause in the battery discharge procedure and lose efficacy.
Said scraggly lines is Any shape or structure, and the groove of said scraggly lines can be any degree of depth.Described rough lines can be the structure of hollow out.
Through projection is set, can prevent effectively that the carbon granule in the blocking bag splashes away from battery case.
Description of drawings
Fig. 1 is a structural representation of the present invention.
1 positive cover, 2 liquid injection holes, 3 vitreums, 4 projections, 5 positive terminals.
