Tokyo Tech team develops low-cost germanium-free solid electrolyte for Li-ion batteries

15 Jul 2017   Electric Cars, Japan

Researchers at Tokyo Institute of Technology have devised a low-cost, scalable approach to developing all-solid-state batteries, improving prospects for scaling up the technology for widespread use in electric vehicles, communications and other industrial applications. Described in a paper in the ACS journal Chemistry of Materials , the approach involves substituting germanium in the solid electrolyte for two more readily available elements: tin and silicon. The new material achieved an ionic conductivity that exceeds that of liquid electrolytes. Reporting the findings, Ryoji Kanno and colleagues stated: “ This germanium-free lithium conductor could be a promising candidate as an electrolyte in all-solid-state batteries. ” All-solid-state systems with solid electrolytes (SEs) are potential candidates for next-generation batteries […]
