Significantly higher storage capacity, safe operation, and longevity: This is what industry and research expect from future solid-state batteries in comparison to conventional lithium-ion batteries. A new research project now aims to develop prototypes for this purpose.

Researchers at the University of Duisburg-Essen (UDE) have started working on a project related to solid-state batteries. According to an announcement, the scientists plan to use amorphous particles of modified silicon nitride as anode material. The special structure of the particles ensures that lithium is distributed very quickly in the storage material. As part of the project, the researchers aim to determine the ideal particle size for the anode material and what the optimal ratio of chemicals in the batteries looks like. At the end of the project, a prototype cell is expected to be developed. The full cells are being produced in the laboratories of the Fraunhofer Institute for Material and Beam Technology IWS in Dresden.

Solid-state batteries are similar in structure to conventional lithium-ion batteries. The distinguishing feature is the solid electrolyte instead of a liquid variant, it is further stated. According to the researchers, solid-state batteries have three advantages over conventional batteries: They are smaller and therefore well suited for use in e-mobility, they contain significantly less flammable material, and they do not use environmentally harmful materials.
