Abstract
The utility model provides a lithium battery connecting piece device, including a microscler locating plate, a buckling plate and a first extension board. Wherein the long positioning plate has a first end and a second end along the longitudinal direction; bending the second end of the long positioning plate to extend vertically and downwardly in a direction away from the second end; the first extending plate extends vertically and horizontally from one side of the bending plate in a direction away from the one side. When the long positioning plate is electrically connected to the wiring assembly of a lithium battery cell and the first extension plate is electrically connected to the lug set of the lithium battery cell in a large area, the charging and discharging requirements of high-rate and large current can be satisfied.
Description
Technical Field
The utility model relates to a technical field is connected to the lithium cell, especially relates to a heavy current charge-discharge lithium cell connection piece device.
Background
In the currently used lithium battery core, a positive plate is welded with a positive pole lug, and the positive pole lug is welded on the inner wall of a shell, so that the shell is electrically connected with a positive terminal. And the negative pole piece is welded with a negative pole tab which is upwards welded at the bottom of the negative pole binding post of the shell. However, the above-mentioned negative electrode tab is led out from the negative electrode plate and then welded to the bottom of the negative electrode terminal, and the processing procedure is complicated; the positive electrode tab is welded on the inner wall of the shell, the negative electrode tab is welded on the negative terminal, the quality of the welding point is not easy to control, and the welding point is always in point contact, so that the problems of poor conduction and heat dissipation are easily caused, and the lithium ion battery is not suitable for charging and discharging with high multiplying power and large current.
