At the Battery Show and EV Tech Expo 2025 in Detroit recently, the Able Electropolishing team had the opportunity to meet with manufacturers and suppliers of batteries and battery parts across industries that included automotive, aerospace, consumer electronics and medical technology.
It was a fascinating showcase of emerging applications and innovation in battery technology, safety and manufacturing. We had the privilege of meeting many attendees and sharing information about the benefits of electropolishing for improving the durability and performance of battery parts.
Electropolishing can ensure that aluminum and copper parts used in EV battery manufacturing have a defect free surface finish or used for surface improvement in preparation for plating. The process can also be used as the final finishing step.
How does electropolishing work? That was just one of the questions we heard at the show. Here are some of the others.
Frequently Asked Questions about Electropolishing from the 2025 Battery Show & EV Tech Expo
Does electropolishing apply a coating to the part surface?
No. Electropolishing removes a precise and consistent layer of surface material to eliminate defects including microburrs and microcracks. This is why it is sometimes referred to as a “reverse plating” process.
How does electropolishing improve plating results?
By leaving parts free of burrs and other defects and creating subtly radiused edges, electropolishing minimizes the risk of cracking, flaking, peeling, blistering, discoloration and coating separation or buildup and helps ensure good adhesion of plating materials.
Does electropolishing achieve good results for copper parts?
Yes, electropolishing is valued for its ability to enhance copper’s durability, electrical conductivity and corrosion resistance.
How precisely can material removal be controlled with electropolishing?
The ability to precisely control the degree and accuracy of surface material removal is a key advantage of the Able Electropolishing process. The material removal control for copper and aluminum is +/- .0002”.
What are the primary benefits of electropolishing for battery parts?
- Improved conductivity
- Creation of smooth slightly radiused edges, minimizing the risk of plating buildup
- Elimination of surface pits and risers
- Elimination of burrs
- Improved microfinish by up to 50%
- Enhanced corrosion resistance
- Enhanced resistance to oxidation
- Parts left in a passive state
