Abstract

The invention relates to a nickel-base high energy battery electrode tab welding process, a laser welding technique is adopted, and a welding production line is achieved. By means of the nickel-base high energy battery electrode tab welding process, the welding between each electrode tab and a nickel-based high energy battery electrode strip can be effectively achieved, the laser welding technique is adopted for increasing the contact area between a battery electrode plate and each electrode tab, the welding strength is enhanced, the battery electrode plate is in close connection with the electrode tags, the internal resistance of a battery is reduced, the conductivity is improved, the high magnification rapid charging and discharging capabilities of a product are enhanced, meanwhile, the welding efficiency of the electrode tabs is raised, the operation is simple, the welding process is applicable to large-scale production and application, and a great production and practice significance is achieved.

Description

technical field [0001] The invention belongs to the field of battery manufacturing, and in particular relates to a nickel-based high-energy battery tab welding process. Background technique [0002] The traditional battery tab welding process generally adopts two welding processes: first, a single piece of tab is spot welded, usually a piece of tab is spot welded for 6-10 points, and then seam welding is performed by a seam welder. This welding method can only meet the general requirements for charging and discharging nickel-based batteries, and cannot solve key problems such as high-rate and high-current charging and discharging, high-current start-up and operation of various equipment; at the same time, this welding method has cumbersome steps and low processing efficiency. Realize mass production of nickel-based batteries. Contents of the invention [0003] The object of the present invention is to provide a high-efficiency nickel-based high-energy battery tab welding ...
