Abstract: A short-circuit prediction device for predicting the presence or absence of occurrence of an internal short circuit in a secondary battery is provided. The secondary battery has a positive electrode, a solid electrolyte, and a negative electrode that contains a lithium alloy. The short-circuit prediction device includes a measurement instrument that measures AC impedance of the secondary battery and a controller that predicts the internal short circuit in the secondary battery.
