Coperion launches RF400 roller feeder for battery electrode coating

Coperion has launched the Coperion K-Tron RF400 roller feeder, a new system designed to improve dry electrode material feeding in battery manufacturing processes.

The RF400 addresses a key challenge in battery production: delivering electrode blends consistently into the calender gap during dry coating operations. According to Coperion, the system uses a combination of a grooved feed roller and a smooth scraper roller to ensure steady material flow while preventing bridging at the outlet.

The roller feeder is engineered to provide uniform material distribution across coating widths of up to 400 millimeters. This helps reduce variability in electrode deposition, which can impact production efficiency and product quality.

The RF400 is intended for laboratory and pilot-scale environments and includes adjustable controls that allow operators to tailor feeding parameters to specific materials and processes. Coperion states that the system is designed for long-term durability in demanding manufacturing conditions.

The feeder integrates with the company’s KCM-III control platform and Smart Force Transducer weighing technology, enabling real-time monitoring and adjustments. This allows manufacturers to maintain precise feed rates and respond to changes in material characteristics.

According to Coperion, the RF400 can help manufacturers improve efficiency by optimizing material usage, reducing waste, and lowering energy consumption in battery production operations.

Jay Daniel, Head of R&D Feeders and Feeding Systems at Coperion K-Tron, said the new roller feeder is designed to support manufacturers as demand for high-performance batteries increases and process requirements become more stringent.
