June 9, 2022: Swiss manufacturer Bühler is to supply “low-carbon” battery mixing technology to UK gigafactory developer Britishvolt, the companies announced on June 7.

Britishvolt said its first gigaplant, in Northumberland, will use large scale Bühler production lines for the manufacture of electrode slurries for the first go-to-market phase of 4.8GWh, which will be expanded to 38 GWh towards the end of the decade.

This corresponds to enough battery cells for well in excess of 300,000 electric vehicles per year, Britishvolt said.

Bühler says its continuous electrode slurry mixing process saves 60% of investment and operating costs while improving battery performance.

Commissioned

The director of Bühler’s battery solutions division, Adrian Spillmann, said: “We use a rotating twin-shaft mixer that combines the necessary process steps such as premixing, homogenizing, dispersing, and degassing in a single, continuously running unit.”

This means material losses are reduced by 95%, due to short start and stop procedures, no manual intervention, a low active mixing volume, and inline process control, the company claims.

Britishvolt’s ramp-up and production lines are scheduled to be commissioned in September 2023 and spring 2024, respectively.

The battery manufacturer said on May 24 it had signed a sales purchase agreement to acquire German battery cells producer EAS Batteries from the Monbat group.
