Abstract
The utility model relates to the technical field of battery production, in particular to a battery cover group. The novel battery cover group comprises an anode cover and an anode column, wherein a net-shaped metal sheet is arranged on the outer surface of the anode column below the anode cover. The net-shaped metal sheet is arranged on the anode column so that the novel battery cover group enlarges contact area of the anode column and a carbon bag, and effectively improves flowability of lithium ions.
Description
Technical field
The utility model relates to the battery production technical field, relates 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 utility model is exactly to the problems referred to above a kind of new lithium battery cap group to be provided.This battery cover group is simple in structure, the both positive and negative polarity reacting balance, and voltage is stable.
The technical scheme that the utility model provides is:
Novel battery lid group comprises positive cover and positive terminal, and the outer surface of the positive terminal of positive cover below is provided with expanded metal sheet.
Concrete, said expanded metal sheet is made up of the grid of parallelogram.
Concrete, said expanded metal sheet is made up of the grid of equilateral polygon.
The utility model increases the contact area of positive terminal and carbon bag through expanded metal sheet 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.Be employed in now and expanded metal sheet is set on the positive terminal improves 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 grid in discharge can not cause in the battery discharge procedure and lose efficacy.
Description of drawings
Fig. 1 is the structural representation of embodiment 1.
1 positive cover, 2 liquid injection holes, 3 vitreums, 4 projections, 5 positive terminals.
Embodiment
Novel battery lid group comprises positive cover and positive terminal, and the outer surface of the positive terminal of positive cover below is provided with expanded metal sheet.Said expanded metal sheet is made up of the grid of equilateral triangle.
