Functional materials research in Finland is open to international partners

Aalto University School of Chemical Technology is looking to boost performance for lithium-ion batteries through doping alloys.

As part of the programme, two research groups from the Aalto University School of Chemical Technology are searching for ways to make lithium-ion batteries more durable, safer and more resistant to moisture and temperatures. Compared to traditional lead-acid batteries, lithium-ion batteries have the advantage of being light in weight so batteries using lithium can be made lighter and smaller in volume.

Researchers have synthesized a series of materials in which the properties of lithium iron phosphate have been systematically changed by replacing iron with small amounts of other elements and studying performance of this series at low temperatures, a process called doping. Finnish companies involved in this research include Sachtleben Pigments Oy, Sun Chemicals, Walki, European Batteries, Akkuser and Outotec.
