Solid-state electrolytes for beyond lithium-ion batteries: A review

Safe energy storage technique is prerequisite for sustainable energy development in the future. Designing Solid-State Electrolytes exhibiting high ionic conductivity, good electrochemical performances, high mechanical/thermal stability, compatible electrolyte/electrode interface is the main concern for developing the next-generation rechargeable batteries. This review presents the state of the art of Solid-State Electrolytes for beyond lithium-ion batteries, mainly, for Sodium-ion batteries, Potassium-ion batteries, Calcium-ion batteries, Magnesium-ion batteries, Zinc-ion batteries, and Aluminum-ion batteries. The main aspects of SSEs, including the synthesis processes, the physico-chemical properties, and the electrochemical performance, are emphasized.
