LITHIUM-ION-CONDUCTING NANOFIBER, NANOFIBER AGGREGATE, COMPOSITE FILM, AND CELL

WIPO Patent Application WO/2020/218306

A1

The problem to be resolved by the present invention is to provide: a lithium-ion-conducting nanofiber that can be used as a cell material and can be reduced in weight and size, the nanofiber being of a thin film type and having excellent lithium ion conduction properties, and exceptional long-term stability, etc.; a nanofiber aggregate; a composite film; and a cell in which the nanofiber, aggregate, and composite film are used.　The present invention pertains to: a lithium-ion-conducting nanofiber in which a mixture containing a lithium salt and a polymer compound having polarization is converted to fine fibers, the ratio of the polymer compound content and the lithium salt content of the mixture being such that the lithium salt content is 1/4 to 1/48 eq with respect to repeating units of the polymer compound; a nanofiber aggregate in which a plurality of the lithium-ion-conducting nanofibers are intertwined; a composite film in which a matrix resin is impregnated among the lithium-ion-conducting nanofibers of the nanofiber aggregate; and a cell having the composite film as an electrolyte film.
