Description
Technical field
The utility model relates to battery, particularly relates to cylinder metal foaming battery, and mainly being provides power source for motor vehicle (as electric motor car, automobile etc.).
Background technology
Along with the rise of oil price and motor vehicle exhaust emission influence to environment, motorcycle is substituted by electric motor car at leisure, electric automobile has started to walk to develop, and as the battery of motor vehicle power source, indexs such as its capacity, discharge cycles life-span and voltage have become the focus that people pay close attention to.Existing battery pole plates is made up of inner frame, binding and battery material, and its defective is: because this cell is a planar structure, little with the contact area of electrolyte, conductive capability is poor; The ability of electrode transmission current is proportional to the contact area of electrode and electrolyte, and therefore the conductive capability of the electrode of existing planar structure is limited, and capacity is low, especially is not suitable for high current charge-discharge; Trouble is produced in planar structure mechanization, and it is big to implement difficulty.And behind general cylindrical cell positive electrode, barrier film and the negative electrode coiling, positive electrode, negative electrode are directly drawn with lug from an end respectively, therefore, influence the power of battery on the one hand, on the other hand because positive electrode, negative electrode material are aluminium foil, Copper Foil, under high current charge-discharge, or behind the bump, occur fracture easily, thereby influence the quality and the useful life of battery.
Summary of the invention
The purpose of this utility model is in order to overcome the shortcoming that prior art exists, a kind of capacity height to be provided, be applicable to high current charge-discharge, long service life, and manufacture craft is simple, helps the cylinder metal foaming battery of mechanized operation.
The technical scheme of the utility model cylinder metal foaming battery is: the positive battery plate that metal foaming is arranged, the negative battery plate of metal foaming and just being positioned at, the battery that barrier film between the negative battery plate is made, housing is installed outside battery, it is characterized in that described battery is metal foaming positive battery plate and the equitant both sides of barrier film and last, lower boundary gap length is L, the equitant both sides of metal foaming negative battery plate and barrier film and last, lower boundary gap length is L, be rolled into columniform battery together, at battery one end that rolls negative electrode cast welding layer is arranged, negative electrode cast welding layer is drawn the negative electrode lug, the other end has positive electrode cast welding layer, and positive electrode cast welding layer is drawn the positive electrode lug.
Cylinder metal foaming battery of the present utility model, because the positive battery plate of metal foaming, the left and right sides of the negative battery plate of barrier film and metal foaming and last, it is the staggered positions of L that lower boundary has gap length respectively, after rolling into cylinder, just can carry out cast welding respectively in positive battery panel edges that exposes and negative battery panel edges, positive electrode cast welding layer is drawn the positive electrode lug, negative electrode cast welding layer is drawn the negative electrode lug, during charging, positron accumulates to the positive battery plate along the positive electrode lug, and negatron accumulates to the negative battery plate along the negative electrode lug.Compare with the metal foaming battery of existing planar structure, it is strong to have a conductive capability, and Capacity Ratio improves 20%, can be used for high current charge-discharge, as car power source, and can improve twice useful life, and it is simple to roll processing technology, helps mechanization production.The upper and lower end face of battery has the cast welding layer respectively, can prevent effectively that the metal foaming positive and negative electrode cell panel of the inside from making moist and get rusty, and anti-oxidation, prolongs battery useful life.
Cylinder metal foaming battery of the present utility model, the positive battery plate of its described metal foaming and the negative battery plate of metal foaming are the electric conductors of a rigidity, silk screen handing-over shape, between the electric conductor of silk screen handing-over shape irregular through hole is arranged, the attached battery material again on its surface, and keep perforate.But the positive and negative cell panel of metal foaming forms several open channels by conductive fabric, simultaneously these knit continuous nodes that the shape thing is connected support this structure can be on all directions through by compression, mechanical shocks such as extension, bending, vibration, acceleration.Adopt this kind structure, can increase the capacity and the volume of battery of cell panel and electrolyte, keep enough mechanism's intensity simultaneously.Its described positive battery plate cast welding layer and negative battery plate cast welding layer are alloy material, isolated better effects if.
