6 FAQs about [Solar container battery box welding method]

How are battery interconnects made?

Spot welding strips and tabs onto batteries in order to make battery interconnects and larger battery pack assemblies is a common production technique. Typically, battery interconnects are made from nickel strips, ideally designed with bifurcations and projections which are then resistance welded using parallel gap or step welding methods.

What is TIG battery welding?

The TIG battery welding process has been tested and proven with a number of high-integrity Lithium Ion designs with excellent electrical and mechanical results, using Nickel, Aluminium and Copper flat sheets to a maximum thickness of around 0.5 mm.

What is a non-contact welding process?

The process is non-contact, has no consumables, offers instantaneous welding once positioned at the weld point location, provides sufficient control over the process to size the weld nugget according to requirements, and provides a number of implementation methods that can be geared toward individual manufacturing requirements.

What is ultrasonic welding?

Ultrasonic welding is commonly used for the joining of the internal electrode battery materials, which are usually constructed of thin foils of aluminum and copper. The remaining joining requirements – including the connections inside the can, and external terminal tab connections – are well suited to resistance, microTIG, and laser welding.

How can high-end battery pack manufacturers reduce costs?

With a constant drive to increase power handling and reduce losses, high-end battery pack manufacturers are looking for methods to attach more conductive interconnects, such as aluminium and copper, while additionally trying to reduce costs through simplifying the interconnect design.

What are the materials joining requirements for battery manufacturing?

There are a number of materials joining requirements for battery manufacturing, depending on the specific type, size and capacity of the battery. Internal terminal connections, battery can and fill plug sealing, tab to terminal connections, and external electrical connections are a few key examples.
