Abstract
A solid-state battery, a battery module, a battery pack, and an apparatus associated therewith are provided. In some embodiments, the solid-state battery includes a solid-state electrolyte, where the solid-state electrolyte includes a sulfide electrolyte layer and at least one polymer electrolyte layer provided on a surface of the sulfide electrolyte layer, and the solid-state electrolyte satisfies the following condition: thickness of the sulfide electrolyte layer≥thickness of the polymer electrolyte layer on one side ≥84.2−80.2 w. The polymer electrolyte layer having an appropriate thickness in this disclosure can improve interfacial infiltration between the current sulfide electrolyte layer and an electrode without seriously reducing the overall energy density of the battery, thereby overcoming defects of sulfide electrolyte in disclosures in solid-state batteries to a large extent and improving cycling performance and safety performance of solid-state batteries.
