Abstract
The utility model discloses a cylindrical lithium ion battery pole piece, which comprises a pole piece body. The cylindrical lithium ion battery pole piece is characterized in thatfixed base bodies are arranged at the two ends of the pole piece body, and the fixed base bodies are respectively provided with a pole ear. The pole ears are arranged on the fixed base bodies, and the pole piece body and the pole ears are fixed together through a plurality of fixed rivets. The cylindrical lithium ion battery pole piece has the beneficial effects that the battery pole piece adopts the rivet welding mode to replace the conventional electric resistance welding, condenser welding and ultrasonic welding, and the structure adopts the physical welding mode, so that the proportion empty welding is greatly reduced, the yield of welding is increased, and the cost of products is reduced.
Description
[technical field]
The utility model relates to a kind of cylindrical lithium ion battery, especially relates to a kind of cylindrical lithium ion battery pole piece.
[background technology]
The pole piece of present known cylindrical lithium ion battery generally adopts welding manner; Basically be to adopt ultrasonic bonding; Ultrasonic welding machine is to utilize ultrasonic wave to make the friction of high frequency between the workpiece contact-making surface make the intermolecular heat that produces rapidly; When this heat is enough big, stop ultrasonic vibration, solidify molten face to accomplish the welding of procedure.Ultrasonic bonding exists the back that works long hours to cause the electronic element instability to produce the phenomenon that rosin joint improves fraction defective owing to soldering tip is overheated, and this defective is unobvious especially simultaneously especially to be welded to each other the workpiece material.
[utility model content]
The purpose of the utility model is to above-mentioned technological deficiency; A kind of cylindrical lithium ion battery pole piece is provided; The structure of the utility model adopts the rivet welding mode to replace conventional electric resistance welding, condenser welding, ultrasonic bond to battery pole piece, and described structure adopts the physics welding manner to greatly reduce the ratio of rosin joint; Improve the qualification rate of welding, reduced the cost of product.
The technical scheme of the utility model is described below: a kind of cylindrical lithium ion battery pole piece; Comprise a pole piece body; It is characterized in that described pole piece body two ends are provided with fixing base, are respectively arranged with a slice lug on the described fixing base; Described lug is placed on the fixing base, and several fixing rivets are fixed together pole piece body and lug.
The utility model according to said structure; Its beneficial effect is; The utility model adopts the rivet welding mode to replace conventional electric resistance welding, condenser welding, ultrasonic bond to battery pole piece; Described structure adopts the physics welding manner to greatly reduce the ratio of rosin joint, has improved the qualification rate of welding, has reduced the cost of product.
[description of drawings]
Accompanying drawing 1 is the structural representation of the utility model.
Pole piece body in the drawings, 2; 3, lug; 4, fixing base; 5, rivet.
[embodiment]
Below in conjunction with accompanying drawing and execution mode the utility model is further described:
As shown in Figure 1; A kind of cylindrical lithium ion battery pole piece comprises a pole piece body 2, it is characterized in that; Described pole piece body 2 two ends are provided with fixing base 4; Be respectively arranged with a slice lug 3 on the described fixing base 4, described lug 3 is placed on the fixing base 4, and several fixing rivets 5 are fixed together pole piece body 2 and lug 3.
