US-based industrial machinery manufacturer BW Converting, a Barry-Wehmiller company, is introducing its Baldwin Electrode Press Industrial Cleaning (EPIC) System, which can work with its Corona Pure systems for cost-efficient battery cell manufacturing.

EPIC automates cleaning in calender processes, specifically for anode and cathode foil production. Operating at up to 302° F (150° C), EPIC is designed to maximize surface cleanliness, leading to higher battery foil quality and productivity.

The system uses a solvent formulated to withstand high heat to clean the calenders automatically with the machine running. The process takes 2-4 minutes, instead of the 45 minutes in anode and multiple hours in cathode typically required, by eliminating the need for cooling and manual cleaning. It uses a lint-free microfilament cloth that absorbs dirt and fluids without scratching the mirror-polished rollers, ensuring continuous, high-quality production.

EPIC also offers customizable cleaning sequences through a digital touchscreen control panel, allowing the operator to adjust wash cycles, detergent dosage and more.

The system can be provided to OEMs who manufacture calendering units or retrofitted onto existing equipment in gigafactories.

BW Converting has also introduced Corona Pure, which provides efficient surface treatment in advanced battery production. Featuring high-performance, durable and easy-to-handle swiveling electrodes, this system is designed to enhance the adhesion of inks, coatings, varnishes and glues across a range of materials.

The swiveling design aims to ensure long electrode life, while the advanced AS-generator minimizes power loss and facilitates seamless external control and data integration.

“This industry often relies on whatever treatment state foil rolls are in, when delivered from their vendor. Placing Corona in line in your battery factory guarantees higher adhesion and better coating performance,” said Dr. Alexander Rau, Baldwin Product Specialist, Corona and Spray.
