On Tuesday, June 20th, global materials technology and recycling group Umicore inaugurated one of the world’s most advanced solid-state battery material prototyping facilities in Olen (Belgium). Solid-state batteries are expected to propel electric mobility and complement Umicore’s world-leading portfolio of battery materials technologies.

The new 600 m² facilities with state-of-the-art installations and equipment support the full chain of solid-state battery development – from the formulation of the materials to battery cell assembly and subsequent testing.

Extremely sensitive to moisture

Umicore has transformed an industrial building on its site in Olen into this unique cutting-edge facility. The site also accommodates the Group’s Research and Development headquarters.

Developing solid-state batteries involves materials that are extremely sensitive to moisture and, therefore, require specialized infrastructures, including exceptionally dry air.

More energy efficient

Humidity levels inside Umicore’s laboratory are at less than 0,1% as 200 000 m3 of dry air is blown through the facilities each hour. Such dry air is essential for accurately testing, analyzing, and developing this next generation of active cathode materials.

The ultra-dry air preserves the stability of battery materials and extends their lifespan, thereby reducing frequent material replacements. The dry rooms where researchers manipulate products are more energy efficient as precise testing and analysis minimize trial and error iterations.

More range and faster charging

Solid-state batteries are the next-generation batteries with performance improvements on several fronts. Their higher energy density will increase the driving range of electric vehicles and allow faster charging.

Replacing today’s liquid electrolyte with a solid one will enhance the safety and lifespan of rechargeable batteries and reduce their size, weight, and, ultimately, cost.
