New Battery Technologies: PEM Collaborates With Dutch "Nanoloy"


The Chair of Production Engineering of E-Mobility Components (PEM) of RWTH Aachen University and the spin-off engineering service provider PEM Motion have entered into a partnership with the Dutch start-up Nanoloy to develop innovative electrodes and production technologies for batteries. The subject of the collaboration is a new type of production concept that allows for previously unusual cell chemistries and makes the use of binders as well as toxic solvents obsolete.

Nanoloy pilot line set up in PEM's eLab

The Nanoloy team led by CEO Alex Koszo and CTO Krishna Tekriwal produces high-performance silicon anodes designed to reduce production costs. The company, which is based in The Hague, Singapore and India, uses a novel plasma coating process as its core technology. Until the second quarter of 2024, the start-up's research and development pilot line is being set up in the PEM's Electric Mobility Laboratory (eLab) facility. PEM had previously supported the proof of applicability for Nanoloy's battery production. The team led by RWTH professors Achim Kampker and Heiner Heimes will support electrode development and scaling up the system technology to gigafactory level.

Improved service life, energy density, and safety

"Our joint goals for batteries produced over the next three years are to increase service life by 33% and energy density by 50% while improving safety and reducing production costs by 40%," says PEM Director Professor Achim Kampker. In this context, Nanoloy is talking about up to 3,000 charging cycles, an energy density of up to 450 watt-hours per kilogram, and production costs of less than 70 US dollars per kilowatt-hour at cell level. According to Nanoloy, the company plans to have a ten-gigawatt-hour production plant in the EU by 2028, the exact location of which is yet to be determined.

Production of solid-state and optimized lithium-ion batteries

The newly configured plasma printer from Nanoloy recently produced promising electrodes, including high-performance anodes with a 50% silicon content. In addition to the production of solid-state batteries as next-generation rechargeable batteries, the pilot line in Aachen also enables the optimization of conventional lithium-ion batteries. The design of innovative production processes for current and future battery generations is one of PEM's main areas of research. Meanwhile, Nanoloy CEO Koszo has more than 20 years of experience in the management of technology companies. In 2019, he was named one of Asia's top 25 innovators by the Cleantech Group.
