Abstract

An all-solid-state battery (10) and an application thereof are provided. The all-solid-state battery (10) includes at least: a first solid electrolyte layer (131) disposed on a side of a positive electrode (11) of the all-solid-state battery (10), with an ionic conductivity of 1×10<-4>~1×10<-2>S/cm; a second solid electrolyte layer (132) disposed on a side of a negative electrode (12) of the all-solid-state battery (10), with an ionic conductivity of 1×10<-3>~2×10<-2>S/cm; and a third solid electrolyte layer (133) disposed between the first solid electrolyte layer (131) and the second solid electrolyte layer (132), with an ionic conductivity of 1×10<-3>~2×10<-2>S/cm. The disclosure may improve resistance of a solid electrolyte membrane to lithium dendrite penetration in the all-solid-state battery, improve the ionic conductivity, electrochemical reduction stability, and compatibility between the solid electrolyte membrane and the positive and negative electrodes, thereby improving cycle life and safety of a battery.
