6 FAQs about [Lithium battery copper busbar production]

Which busbar material should be used in a battery module?

Cooper is traditionally used as busbar material. But the selection of Al busbar material over Cu busbar can reduce the weight and cost of the busbar used in the battery module by 75%. However, the Cu tab to Al busbar gave slightly higher (about 16–20%) resistance over the Cu tab to Cu busbar joint.

How much current does a copper busbar need?

The current is an estimated continuous rating and plotted versus the cross-sectional area in mm 2. The gradient of the “straight line fit” shows that 5.9A/mm 2 is a rough estimate for copper busbar size. However, to be on the safe side of this I would initially size at 5A/mm 2 before doing the detailed electrothermal analysis.

What is the difference between copper and aluminium busbars?

Compared to copper busbars aluminium offers a weight and cost save, but requires an increase in cross-sectional area of ~62%. Hence aluminium busbars need more volume for packaging. The highest conductivity is achieved by high purity aluminium (purity of 99.9 wt% Al and higher) in soft temper.

Can fswed Al-Cu busbar be used with a Li-ion battery pack?

There was no substantial literature on the busbar attached with a Li-ion battery. Hence, the present study details the application of an effective FSWed Al-Cu busbar to a Li-ion battery pack. The FSW busbar has advantages over other welding techniques in the perspective of mechanical and electrical properties.

How to choose a busbar material?

The selection of busbar material and its thickness are based on the current carrying capacity, mechanical and electrical characteristics and cost of the module . The busbar plays a vital role in avoiding excessive heat generation at the tab-to-busbar interconnects.

What is a good size for a copper busbar?

The gradient of the “straight line fit” shows that 5.9A/mm 2 is a rough estimate for copper busbar size. However, to be on the safe side of this I would initially size at 5A/mm 2 before doing the detailed electrothermal analysis. An important aspect to consider in all busbar designs is to consider the environment and the materials.
