Battery Pack Welding Connector
What Is The Battery Pack Welding Connector?
Battery spot welders connect metal plates to the contact points (terminals) of the battery.
This process requires the battery spot welder to be carried out.
Usually, battery interconnects are made of pure nickel 201 strips, ideally designed with bifurcations and protrusions, and then welded using parallel gap or step welding methods.
Why Pure Nickel Strip is The Most Important Material For Battery Pack Welding Connector?
The grade Nickel 200/201 strip, which conforms to the ASTM standard.
It’s commercially pure (99.6% and higher) with good mechanical properties. It also has good spot welding properties and high tensile strength. So when use the pure nickel strip to make battery pack,the spot welding property is good.
As a leading China pure nickel strip foil for battery supplier, HZW manufactures and produces different thickness and width of pure nickel strip foil. HZW manufactured the pure nickel strips make excellent battery connectors because they have a low electrical resistance.
