All-solid-state batteries

Metal ion batteries have been widely exploited as advanced energy storage devices for various applications such as portable electronics and electric vehicles. Current commercial metal ion batteries, however, are exposed to potential safety hazards owing to the use of flammable liquid organic electrolytes. Most recent major incidents of fires due batteries were caused by ignition of the liquid electrolyte as a result of overcharging or operational misuse. Great efforts have therefore been directed towards the development of fundamentally safe technological solutions using solid inorganic electrolytes.
