The structure not only is convenient for the series-parallel connection operations of battery packs, but also reduces the resistance between the conducting wires and the anode and the cathode to the minimum, and is helpful for the battery to discharge at a higher multiplying power and have a longer cycle life. The maintenance procedures for the battery packs are simplified and the damages to the battery are avoided.
Description
[technical field]
The present invention relates to cylindrical lithium-ion power battery, relate in particular to architecture advances the housing and the combination cover cap of cylindrical lithium-ion power battery.
[background technology]
Along with world energy sources crisis and human continuous reinforcement to environmental consciousness, high power capacity, the demand of high-power mobile reserve power supply is increasing.Characteristics such as lithium ion battery has voltage height, capacity height, the life-span is long, security performance is good have broad application prospects in each side such as electron trade, electric automobile, Aero-Space, national defense and military.But present PACK battery producer all is to use more traditional nickel strap welding manner, and several cells are carried out the connection in series-parallel combination.And all there are many drawbacks in the cell that adopts existing cylindrical lithium-ion power battery housing and block to produce when the maintenance of connection in series-parallel and battery pack.
1. battery pack adopts the crosspointer resistance welder to weld when series connection and parallel connection, must be at the quality of material to be welded, pressure, energy and the time that thickness is come suitable point of adjustment welding machine during spot welding.If there is adjusting improper: excessive as pressure, then the housing of battery is understood gross distortion; Too small as pressure, phenomenons such as rosin joint or not prison welding be solid will appear; Regulate too highly as energy, then the heat that produces during spot welding is high more, and spills with spark, sometimes even can puncture metal nickel strap and battery container, causes battery to scrap; Regulate too lowly as energy, can occur phenomenons such as rosin joint or not prison welding be solid equally.
2. battery pack in use may occur unusually, cisco unity malfunction.This just need detect, disassemble, keep in repair, re-assembly battery pack.And when disassembling, be undoubtedly the loaded down with trivial details and time-consuming work of requiring great effort of part with the battery pack that the metallic nickel tape welding connects.The crator that battery plus-negative plate end face after disassembling is left over must be through using after polishing, the polishing.But the nickel coating on the battery container surface that the process grinding and buffing is handled is by heavy damage, and time one length will be got rusty, and the useful life of battery pack and security performance will be had a greatly reduced quality.Moreover have sags and crests unavoidably through the battery plus-negative plate end face of grinding and buffing, and when such battery welded once more, difficulty was bigger, and the probability that rosin joint occurs, punctures metal nickel strap and battery container is bigger.So each maintenance battery all will through disassembling-detect-polish-polish-tear the operation of film-coating-welding open, damage is seriously.
Therefore, how to solve many difficult problems that the higher cylindrical lithium-ion power battery group of high power capacity, high power, security performance is brought when connection in series-parallel and maintenance, become the important topic of those skilled in the art's research.
[summary of the invention]
Purpose of the present invention solves the problems of the prior art exactly, proposes a kind of cylindrical lithium-ion power battery, can make things convenient for the assembling and the maintain and replace of battery, and can avoid keeping in repair the damage to battery.
For achieving the above object, the present invention proposes a kind of cylindrical lithium-ion power battery, comprise housing and the anodal assembly that is fixed on case top, be welded with anodal nut on the described anodal assembly, positive electrode end bolt has been threaded on the described anodal nut, also comprise the negative pole assembly, negative electrode end bolt has been threaded on the described negative pole assembly.
As preferably, described anodal assembly comprises positive ear connecting sheet, explosion-proof valve and nickel plating block, and described explosion-proof valve is arranged between positive ear connecting sheet and the nickel plating block, and anodal nut is welded on nickel plating blocks a shot.
As preferably, adopt anodal seal to seal between described positive ear connecting sheet, explosion-proof valve, nickel plating block and the housing.Improved the sealing property of battery.
As preferably, described positive ear connecting sheet adopts laser welding to be connected with burst disk, and anodal nut is connected with nickel plating block employing ultra-sonic welded.Adopt rational welding manner, avoided the generation of phenomenons such as rosin joint.
As preferably, described negative pole assembly comprises negative pole nut, negative pole bolt, and described negative pole nut is threaded with negative pole bolt and negative electrode end bolt respectively, and the negative pole nut is arranged on enclosure interior, and negative pole bolt and negative electrode end bolt are arranged on outside.Syndeton is simple, at the bottom of the cost.
As preferably, adopt the negative pole seal to seal between described negative pole nut, negative pole bolt and the housing.Improved the sealing property of battery.
Beneficial effect of the present invention: the present invention is provided with positive electrode end bolt and negative electrode end bolt respectively at the housing two ends, when lithium-ion-power cell is carried out connection in series-parallel, only need connect copper positive electrode end bolt and negative electrode end bolt respectively, and get final product with anodal nut, negative pole nut screwing clamping with lead.This structure is not only convenient to the series-parallel operation of battery pack, and it is minimum that resistance between lead and both positive and negative polarity is dropped to, and helps battery than the discharge of high magnification and long cycle life.Battery pack keeped in repair not to be needed through polishing, polish, tear open loaded down with trivial details operations such as film, coating, welding yet, directly to positive electrode end bolt and negative electrode end bolt screw unscrew just passable, not only made things convenient for operation, and avoided damage fully battery.
Feature of the present invention and advantage will be elaborated in conjunction with the accompanying drawings by embodiment.
