Composite solid electrolyte material of oriented ordered structure LLTO matrix, and preparation method and application thereof

The invention discloses a composite solid electrolyte material of an oriented ordered linear structure LLTO matrix. Oriented ordered linear structure LLTO is taken as the matrix, and an organic solid electrolyte as a reinforcing phase is uniformly distributed and injected into the matrix, so that the whole composite electrolyte material has an oriented linear structure. The invention also provides a preparation method of the composite solid electrolyte material with the oriented ordered structure LLTO as the matrix. The method is simple to operate and low in cost, and the prepared composite solid electrolyte material for the lithium ion battery is excellent in electrochemical performance; and the organic solid electrolyte provides toughness and strength, and the structural stability is good. The prepared composite electrolyte has relatively high lithium ion conductivity and a relatively wide electrochemical window at room temperature, the directional orderliness of the solid electrolyte between a positive ele
