Researchers from Justus Liebig University in Gießen, University of Marburg, Max Planck Institute for Iron Research, and the University of Toronto have conducted research on the properties of silicon anodes in solid electrolyte batteries. The team concluded that these anodes have tremendous potential to improve the efficiency of these batteries. The research results regarding the stability, chemomechanics, and aging process of silicon electrodes have been published in the journal Nature Materials.
The research was based on a combination of different experimental and theoretical methods to quantitatively assess the lithium transport in the electrode, the significant volume changes of silicon during charging and discharging processes, and the reaction with the solid electrolyte.
“This comprehensive and fundamental analysis is an important step towards the possible utilization of silicon as electrode material in solid electrolyte batteries, which are currently the subject of intensive international research,” said Prof. Janek, one of the study’s authors.
The researchers emphasize that the development of efficient batteries is essential in various fields, and the demand for them is rapidly growing. Therefore, research and development of electrochemical energy storage systems, including those for electromobility, are one of the most crucial areas of work in materials science worldwide.
It is important not only to increase the capacity and charging speed of batteries but also to improve their lifespan, safety, availability of resources, and CO2 balance.
Research on silicon anodes in solid electrolyte batteries is promising and provides a fresh perspective on the development of efficient batteries with enhanced durability.
