New and more sustainable materials

The Solid State Materials Chemistry group, ESYMAT, has started a new line of research dedicated to the development of new materials for magnesium batteries and their future use in portable electronic devices or electric vehicles. The project titled 'Better magnesium batteries for a more sustainable society', led by Professor Alois Karl Kuhn, Professor of Inorganic Chemistry, has recently been funded by the Ministry of Science and Innovation as part of the Projects on Ecological Transition and Digitisation Transition (TED). The research team is made up of the university's professors, Flaviano García Alvarado, Pilar Díaz Carrasco, José Ángel Martínez González and researchers Julián Cáceres Murillo and Nerea Solís Barba, as well as researchers from the Complutense University of Madrid and the University of Bialystok (Poland).

"Batteries play a central role in driving the electrification of our society, especially in carbon-free land mobility. However, current lithium-ion batteries, based on essential raw materials such as lithium and cobalt, cannot meet the demands, energy requirements and environmental economic sustainability due to the increasing demand for long-life electronic devices and the imperative need to extend the still limited range of electric vehicles," explains Professor Alois Kuhn.

In addition, safety issues associated with lithium-ion batteries remain unresolved. Kuhn stresses: "There is therefore an urgent need to develop new and sustainable systems for energy storage. Since magnesium is much more abundant and cheaper than lithium, magnesium batteries are a very promising alternative to lithium-ion batteries”.

The ESYMAT group's project focuses on the development of more efficient, clean, safe, economical, and environmentally friendly and sustainable magnesium battery cathodes to promote a zero carbon scenario and contribute to mitigating climate change. The research is part of the strategic project aimed at the ecological and digital transition of the State Plan for Scientific and Technical Research and Innovation for the period 2021-2023, within the framework of the Recovery, Transformation and Resilience Plan, in line with the 'Horizon 2020' programme on Research and Innovation for Sustainable Batteries.
