With the rapid development of lithium battery automobile industry,
the PACK connection problem of lithium battery becomes more and
more prominent. There are thousands of battery packs for many
complete coaches, the positive and negative electrodes of the
single cell are made of aluminum foil and copper foil, and how to
realize the safe, reliable, light and simple series and parallel
connection of lithium battery packs is the bottleneck technology
that restricts the development of lithium battery automobile
industry.Our company has developed two copper clad aluminum
composite materials, copper clad aluminum composite base materials
and copper clad aluminum composite transition film for the
connection of lithium batteries by the independent innovation. Base
materials: The copper clad aluminum composite base materials are
made of the 3mm thick copper materials and the 10mm thick aluminum
plate, to complete the copper collector connection of the copper
negative electrode, while the aluminum is connected with the
external aluminum plate, so that two exposed electrodes of the
battery pack are of aluminum, which can be connected by the normal
laser welding technology. Connecting sheet materials: There is a
10mm composite copper strip in the middle of aluminum sheet; the
copper strip is connected with the inner copper collector through
copper rivets, and the aluminum plates on both sides are used for
the series and parallel connection of single cells.Product SizeIt
is customizedon the request of customers.Product FeaturesIt is high
bonding strength, to realize the metallurgical bonding between
copper and aluminum. There is no contact resistance between copper
and aluminum, so it can provide stable and reliable
quality.Technical ParametersBonding Strength ≥100MPa /*
