Breakthrough material could help replace lithium cells, lead to potassium batteries | Many of the highest-performing potassium-ion battery designs currently use cathodes made from Prussian White.
A team of chemists from the University of Glasgow and experts from Helmholtz Institute Ulm have developed a material from chromium and selenium, potentially transforming potassium-ion battery production with a more cost-effective alternative to lithium-based solutions.
This latest breakthrough advances potassium-ion batteries toward becoming a practical alternative to lithium-ion systems, thanks to potassium’s abundance and favorable properties, including rapid charging. “Potassium is a much more abundant material, and potassium-ion batteries have a lot of potential as an alternative method of storing and delivering large amounts electricity. Adopting potassium-ion batteries for stationary storage purposes could help free up lithium resources for use in more energy-intensive mobile applications in the future,” Ganin explained.
