Abstract
The utility model provides a lithium ion battery cover plate of a liquid state aluminium casing, belonging to the technical field of lithium ion batteries. The lithium ion battery cover plate of a liquid state aluminium casing comprises a top plate and a rivet fixed in the top plate, a sprue is arranged on the top plate, and a locating groove is arranged on the outer end surface of the top plate. Aluminium and nickel composite belt welding precision is improved by the lithium ion battery cover plate of a liquid state aluminium casing, the distance of composite belts with the cover plate edges is controllable, and welding skewness can not occur. Position consistency is improved as aluminium and nickel composite belts in the locating groove are located by face pad pits and the locating groove. The efficiency is higher than that of marking or clamp locating welding.
Description
Technical field
The utility model relates to lithium ion battery, relates in particular to a kind of liquid aluminium case lithium ion battery cover plate.
Background technology
The housing of liquid aluminium case lithium ion battery is anodal; need be on battery bottom or cover plate during assembling finished product battery (homopolarity) spot welding or ultra-welding aluminum-nickel composite band; the welding of convenience and baffle; the comparatively general and operation easily of the welding of bottom; and homopolarity welding will be considered the corresponding of the position that hollows out with the face pad; required precision to aluminium nickel composite band position is higher, and crooked and eccentric outward appearance precision and the consistency of all can causing is poor, causes to do over again and the client returns goods in batches.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of liquid aluminium case lithium ion battery cover plate that makes things convenient for welding of aluminum nickel composite band is provided.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of liquid aluminium case lithium ion battery cover plate comprises top board and is fixed in wherein rivet that top board is provided with liquid injection hole, and the top board outer face is provided with location notch.
Described location notch is a rectangle.
Described rivet is arranged at the central authorities of described top board, and described location notch and described liquid injection hole are arranged at the both sides of rivet respectively.
The beneficial effects of the utility model: aluminium nickel composite band welding precision improves, and is controlled with the distance of side edge thereof, can not cause welding crooked; Consistency improves, the face pad hollow out with location notch and location notch in aluminium nickel composite band all linked with one another, guarantee the consistency of position; The efficient height, more faster than line or the welding of anchor clamps location.
