Metso Launches Solution for Li-ion Battery Material Production

Metso is launching the pCAM plant, an intelligent solution for the manufacturing of precursor cathode active material, which is needed in the production of lithium-ion batteries.

Centered around an energy-efficient pCAM reactor, a PSI 1000 particle size analyzer, and a pCAM process control, Metso’s pCAM plant integrates advanced technology and decades of know-how to ensure an energy-efficient and sustainable production process.

“The growing use of high-performance lithium-ion batteries with enhanced energy density, fast charging capabilities, and improved safety features is driving the demand for high-quality and sustainable precursor materials. As a strong and reliable partner for the development of lithium hydroxide and other battery minerals projects, we are the first Western supplier able to also deliver an optimized pCAM plant for the manufacturing of premium precursor cathode active material,” said Mikko Rantaharju, vice president, Hydrometallurgy at Metso.

For active cathode precursor manufacturing, Metso’s offering ranges from optimized raw materials selection to design and delivery of the plant and related services. The production process consists of metal sulfate feed preparation, co-precipitation of mixed metal hydroxide, and filtration. The innovative design of the OKTOP reactor used in the process enables high throughput with a smaller footprint for batch, semi-batch and continuous operation with one reactor set-up, and improved yield thanks to advanced process control and on-line analyzers.

Metso uses its in-house pCAM process development, testing, and pilot facilities. The Metso pCAM plants are Planet Positive-certified, ensuring low energy and water consumption. “Based on Life Cycle Impact Assessment (LCIA), we found that the Metso pCAM process features remarkable sustainability benefits; it reduced water consumption by ~52% and CO2 emissions by ~31%. Also, power usage decreased by ~27%," explained Rantaharju.

Metso provides sustainable technology, equipment, and services for all ore types, including the critical minerals required for a responsible energy transition, supported by its Planet Positive offering. As a strong and reliable partner for battery minerals development projects, Metso can deliver the whole production process – from mine to battery materials, and recycling of black mass. Metso is currently supporting several battery minerals projects that are in the study, piloting, engineering, or delivery phases.
