The invention relates to a lightweight aluminum-
nickel composite
busbar processing method which is implemented as follows: selecting a
nickel tape and an aluminum tape, performing cleaning treatment on the to-be-combined surfaces of the
nickel tape and the aluminum tape; hot-pressing and compounding the nickel tape and the aluminum tape in an
inert gas environment; performing
polishing treatment on the outer surface of a compounded product and performing annealing treatment in a bright annealing furnace
after treatment; and calendaring an annealed product multiple times till the required thickness is reached. The lightweight aluminum-nickel composite
busbar processing method provided by the invention has the benefits that two materials, namely aluminum and nickel are compounded into a whole through a calendaring compound
machine by fully utilizing the plastic deformation of metals and a principle of
atomic diffusion between the metals, so that no re-connection is required in a local
spot welding manner; after the two materials are compounded into a whole through calendaring, the
contact resistance between the materials is far less than that of a local
welding product after
stamping, so that the loss of a battery after
welding is reduced, and the service life of the battery is prolonged; the compounded material is flexible in product appearance design, and the product can be quickly delivered by utilizing an
etching technology; therefore, the lightweight aluminum-nickel composite
busbar processing method is very conducive to the development of new products.
