Healing ceramic electrolyte degraded by lithium dendrite

Tech Online Things

A research team in the Department of Electrical and Electronic Information Engineering at Toyohashi University of Technology and the Department of Chemistry at University of Calgary has investigated the effect of post-annealing for healing Li garnet solid electrolyte degraded by the growth of Li dendrites. The ionic conductivity of the annealed solid electrolyte was slightly lower than that of the electrolyte before annealing but was retained above 10-4 S cm-1 at room temperature. The electrochemical results obtained indicate the possibility of reusing the solid electrolyte degraded by the growth of Li dendrites in another all-solid-state Li battery.
