Abstract
An all-solid secondary battery includes: a cathode layer including a cathode active material; an anode layer; and a solid electrolyte layer disposed between the cathode layer and the anode layer, wherein at least one of the cathode layer, the anode layer, or the solid electrolyte layer includes a phase-transition solid electrolyte material, wherein upon heating, the phase-transition solid electrolyte material undergoes a phase transition from a first phase to a second phase, and the second phase has an ionic conductivity less than the ionic conductivity of the first phase.
