Whatever the bumps along the road, the future of the automobile industry is electric – and the future of the EV auto industry is built on the reliability, safety and performance of its batteries.
That’s a landscape in which electropolishing can play an important role in ensuring that aluminum and copper parts used in EV battery manufacturing can be produced with the highest quality surface finish.
Electropolishing provides EV battery manufacturers with a precise, controllable and effective process for eliminating surface defects and improving the conductivity of aluminum and copper parts. Electropolishing is effective for both pre-plating surface improvement, or as the final finishing step.
Copper Alloys Electropolished
- C101 Copper
- C110 Copper
- Beryllium Copper
- Copper-Nickel
- Aluminum Bronze
Combining a chemical bath and an electrical current, electropolishing enables controlled and consistent removal of surface material with Ra improvement of up to 50%.
The ultrasmooth finish is free of burrs, microcracks, and other surface anomalies left behind by machining processes. The electropolishing improves conductivity of aluminum and copper parts used in EV battery fittings, connectors and other electrical components.
Benefits of Electropolishing for EV Battery Components
Here’s an overview of what electropolishing can do for your EV battery parts:
- Improve conductivity
- Smooth radiused edges
- Eliminate surface pits and risers
- Eliminate burrs
- Improve microfinish by up to 50%
- Enhanced corrosion resistance
- Enhanced resistance to oxidation
- Leave parts in a passive state
Electropolishing Excellence & Innovation for EV Battery Manufacturers
A pioneer of the process, Able Electropolishing has 70 years of experience and collaboration with engineers in industries that includes automotive, aerospace, electronics, medical manufacturing, semiconductor manufacturing and more. We often start at the very beginning, with consultation in the prototyping stage to ensure that finishing considerations are incorporated into part design.
Our process is customized to ensure the highest quality results for a wide variety of parts, with custom rack makers on each shift 24/5 to ensure that the most fragile or intricate parts are finished with precision and consistency across all surfaces.
We use robotic automation to ensure consistent and repeatable results and our start-to-finish customer service includes sourcing, logistical and supply chain support – with the goal of helping our customers get to market quickly.
