| description | The invention discloses a sulfide electrolyte, a preparation method and application thereof, and belongs to the technical field of solid-state batteries, the molecular formula of the sulfide electrolyte is as follows: Li < 7 > P < 2-x > M < x > S < 8-y > O < y > X, X is one or more of F, Cl, Br and I; m is one or more of As, Bi and Sb, x is more than or equal to 0.01 and less than or equal to 1, and the ratio of x to y is 2: 5. According to the invention, the M element is adopted to replace a part of P element in the sulfide electrolyte, and the O element is adopted to replace a part of S element in the sulfide electrolyte, so that the electrolyte with higher air stability and higher ion mobility is obtained, and the air stability and high pressure resistance of the sulfide solid electrolyte are improved; the lithium stability is improved, the ionic conductivity is increased, and the problems that the structure is changed and the ionic conductivity is reduced due to irreversible chemical reaction between the |
