Abstract
The present invention relates to a kind of battery electrode columns, it is for large capacity rectangular cell afflux, including pole body and 2 guide lugs confluence pieces, pole external surface contains screw thread and is locked for battery case cap, guide lug confluence piece is symmetrically welded in pole post tips, guide lug confluence piece is rectangular-shaped in unfilled corner, increases the bonding area of confluence piece and guide lug to greatest extent.
Description
Technical field
The present invention relates to field of chemical power source, and in particular to a kind of battery electrode column.
Background technique
With the fast development of electric car, energy storage field in recent years, the requirement to battery capacity is increasing, small-sized
Cylindrical battery is due to afflux bottleneck, the charge and discharge of unbearable larger current, it is contemplated that battery high current charge-discharge and heat dissipation, one
As designed using rectangular cell and meet high capacity cell demand.
The present invention provides a kind of rectangular cell battery electrode column, the battery electrode column have Unit Weight load capacity it is strong,
The advantages of welding afflux convenient for guide lug.
Summary of the invention
The purpose of the present invention is to provide a kind of battery electrode columns.
The technical scheme is that a kind of battery electrode column, it is comprising pole body and 2 guide lug confluence pieces, the pole
The pole external surface of column contains screw thread and is locked for battery case cap, and guide lug confluence piece is symmetrically welded in pole post tips.
According to the above method, guide lug confluence piece is rectangular-shaped in unfilled corner, increases the welding surface of confluence piece and guide lug to greatest extent
Product.
According to the above method, pole body material is one kind of iron nickel plating, pure nickel, red copper nickel plating and aluminium.
According to the above method, guide lug converges piece material for iron nickel plating or pure nickel.
The beneficial effects of the present invention are: root battery electrode column according to the present invention can increase the welding surface of guide lug and the piece that converges
Product reduces guide lug bending curvature to improve battery qualification rate.
Detailed description of the invention
It is attached that Fig. 1 shows cell embodiments pole column structure figure of the present invention and cross-sectional views.
Attached drawing 2 indicates cell embodiments battery pack welding schematic diagram of the present invention.
Label declaration:
01 pole body
02 guide lug confluence piece
03 brazing or argon arc welding
04 guide lug
05 pole group
Specific embodiment
Embodiment 1
By the cathode containing guide lug, diaphragm, containing guide lug anode, successively lamination forms pole group, and positive and negative anodes guide lug is divided into two
It is partly welded in the guide lug confluence piece outer surface of pole respectively, the gap between pole guide lug confluence piece can be used as welding equipment electricity
Pole installation site, welding schematic diagram are as shown in Fig. 2.
This field inspiration according to the present invention, does not depart from improvement that scope of the invention is made and modification all should be in this hair
In bright protection scope.
