Driving Innovation in Battery Technology with WAB Process Technology Solutions

Wednesday, 7 May 2025

Understanding how batteries work is crucial for optimising production processes. A battery operates by converting chemical energy into electrical energy, facilitated by four key components: the anode, cathode, separator, and additives. The anode (e.g., graphite) releases electrons, while the cathode (e.g., LFP: lithium iron phosphate) receives them, ensuring efficient energy transfer. The separator prevents short circuits and additives enhance battery stability and longevity.

WAB’s advanced milling solutions significantly improve battery material processing. A study on grinding LFP as cathode material demonstrated the superior performance of the DYNO®-MILL UBM compared to conventional solutions, achieving fine particle sizes with greater efficiency.

For anode materials like metal silicon, precise wet milling is essential. Trials at our Process Technology Centre (PTC) in Switzerland reduced energy consumption by over 35% compared to previous setups. This demonstrates the DYNO®-MILL UBM’s efficiency in meeting production demands.

Additionally, dispersion control of carbon nanotubes (CNTs) is crucial for improving battery performance. CNTs agglomerate easily, but optimal formulations and processing techniques can ensure uniform distribution, maximising their benefits while maintaining manageable viscosity levels.

The DYNO®-MILL UBM’s compact design significantly lowers costs compared to larger mills, which consume more than twice the energy per output (kWh/t). This makes the DYNO®-MILL UBM a highly efficient, cost-effective solution.
