| titleOfInvention | A high-voltage resistant composite solid electrolyte and preparation method thereof, and all-solid-state lithium battery |
| abstract | The invention discloses a high-voltage-resistant composite solid electrolyte, a preparation method thereof, and an all-solid-state lithium battery, and relates to the technical field of lithium ion batteries. Among them, a high-voltage-resistant composite solid electrolyte comprises a first composite solid electrolyte layer and a second composite solid electrolyte layer. The electrolytic layer is formed by hot pressing; the first composite solid electrolyte layer includes a COFs matrix and a polymer electrolyte A supported on the surface of the COFs matrix, and the polymer electrolyte A includes polyethylene oxide, bismuth trioxide, lithium salt and polyvinylidene fluoride; The second composite solid electrolyte layer includes a COFs matrix and a polymer electrolyte B supported on the surface of the COFs matrix; the polymer electrolyte B includes polymethyl methacrylate, bismuth trioxide, lithium salt and polyvinylidene fluoride. The composite solid electrolyte of the present application not only widens the electrochemical window of the solid electrolyte, reduces the interface resistance, improves the interface stability of the positive and negative electrodes and the lithium ion transport performance, but also can be applied to the lithium metal negative electrode and the high-voltage ternary positive electrode at the same time. Improve battery cycle performance. |
