High-magnification solid electrolyte silicon integrated electrode and preparation method and application thereof

The invention provides a high-magnification solid electrolyte silicon integrated electrode and a preparation method and application thereof. The solid electrolyte silicon integrated electrode comprises a negative electrode and a solid electrolyte, wherein the negative electrode comprises the following raw materials: silicon powder, lithium titanium aluminum phosphate, a conductive agent and a binder; the solid electrolyte comprises the following raw materials: lithium titanium aluminum phosphate, polyvinylidene fluoride-hexafluoropropylene and lithium salt. The solid electrolyte silicon integrated electrode with a firm electrode/electrolyte interface is constructed on the negative electrode in situ through the component modification of the electrode and the electrolyte and the design of a composite structure, so that the problem of poor rate capability of the silicon-based solid-state battery is solved, and the preparation of the high-capacity, high-rate and high-safety silicon-based solid-state battery suppo
