Description
Technical field
The utility model belongs to the battery parts, is specifically related to a kind of battery cover.
Background technology
As the rechargeable battery of a new generation, lithium ion battery has the voltage height, has extended cycle life, advantage such as capacity is big, environmental protection and be subjected to a lot of users' favors.At present, increasing electronic equipment has adopted lithium ion battery as its energy.And electric tool, electric bicycle, electric motor car have proposed new requirement to the fail safe of lithium ion battery and power and consistency.How to improve the fail safe of lithium ion battery, thereby the internal resistance that reduces battery improves its power and unanimity is not only relevant with technology with prescription, also relevant with the structure of battery cover board, be relevant specifically with the material type selecting of the electrode connecting structure of cover plate and used part.In the prior art, lithium ion battery manufacturer adopts nickel material or stainless steel to make electrode mostly and draws syndeton, and the resistance of the cover plate material therefor of this structure itself is big, in case the battery misoperation causes short circuit, the battery heating is severe, and fail safe especially short circuit safety does not have guarantee.
Summary of the invention
The purpose of this utility model is to provide a kind of low-resistance battery cover group, to address the above problem.
The technical solution of the utility model is: low-resistance battery cover group, it comprises battery cover board, battery cover board is provided with explosionproof hole, be attached with rupture pressure disc on the explosionproof hole, battery cover board offers two anodal fairleads and two negative pole fairleads, one side of battery cover board is riveted respectively and is connected aluminium anode ear and copper negative electrode lug, and the opposite side of battery cover board is riveted the anodal connecting plate of nickel-clad copper and the negative pole connecting plate of nickel-clad copper respectively; Be provided with sealing gasket between anodal connecting plate and negative pole connecting plate and the battery cover board, be provided with insulating trip between anode ear and negative electrode lug and the battery cover board, rivet passes anodal fairlead and negative pole fairlead and anode ear and negative electrode lug, anodal connecting plate and negative pole connecting plate and battery cover board riveted joint.
Described sealing gasket comprises seal block, and seal block is provided with the sealing shroud that is connected sealing with anodal fairlead with the negative pole fairlead, and sealing shroud is offered the rivet axis hole.
Described anodal connecting plate and negative pole connecting plate comprise base plate, and base plate is provided with rebound, and rebound connects draws connecting plate, draws connecting plate and base plate not in same plane.
The high safety of this battery cover group, low internal resistance, have the lithium ion battery cover board part and the syndeton of high power discharge, make it not only safe when user's misoperation causes battery short circuit, and the battery of this structure also is fit to high current charge-discharge.Adopt copper matrix connecting plate and copper negative electrode lug, reduce internal resistance greatly, the sealing effectiveness of sealing gasket is better, safer simultaneously.This electrode is drawn syndeton, and the battery process for assembling and welding is simple to operate, has improved product percent of pass, product quality, has reduced production cost.
