Summary: | The invention discloses a fiber diaphragm, a preparation method thereof and application of the fiber diaphragm in an in-situ polymerization solid-state lithium battery, and relates to a fiber diaphragm and a preparation method and application thereof. The problems that an existing in-situ polymerization solid-state lithium battery is poor in rate capability, fast in capacity fading and short in cycle life are solved. The fiber diaphragm is prepared from a polymer mixed solution containing lithium ion conductor nanotube filler through electrostatic spinning and water-soluble phase separation. The preparation method comprises the following steps: carrying out electrostatic spinning and calcining on a mixed solution of metal salt and a polymer to obtain a lithium ion conductor nanotube; carrying out electrostatic spinning on the fiber membrane and a mixed solution of polymer powder, and carrying out water-soluble phase separation to obtain a fiber membrane; blade-coating the gel electrolyte precursor solution on |
