Abstract:Solid-state
potassium batteries are potentially supplementary to
lithium batteries in large-scale energy storage due to their low cost,
high safety, and energy density. However, potassium-ion solid electrolytes
are quite limited and deliver lower ionic conductivities than lithium
or sodium counterparts. Herein, K2Mg2TeO6, an underexplored potassium-ion solid electrolyte with comparable
high ionic conductivity, the capability to suppress metallic K dendrites,
and mechanical-chemical and electrochemical stabilit… Show more
