The present disclosure relates to the field of solid-state electrolytes, and in particular to a high-strength solid-state electrolyte membrane in which a polyolefin membrane is used as a main body and a continuous lithium conducting channel is embedded in the main body. According to the high-strength solid-state electrolyte membrane provided by the present disclosure, polyolefin is used as a main body framework, and a lithium conducting material is dispersed in dimensional spaces of the main body to form a continuous lithium conducting channel, so that the conduction of lithium ions is implemented without using an electrolyte, thus implementing high strength and good processing performance. The thickness of the solid-state electrolyte membrane can be controlled by means of stretching, thus facilitating preparing a composite electrolyte membrane having a corresponding thickness and strength according to actual requirements. La présente invention a trait au domaine des électrolytes à l'état solide, et concerne
