PROBLEM TO BE SOLVED: To provide a cell separator, an ion conductor and a battery and a manufacturing method thereof which make it possible to improve cycle characteristics of the battery.SOLUTION: A cell separator consists of inorganic oxide fine particles having a lithium element and capable of absorbing a liquid component which are dispersed into a base material containing a high polymer substrate, an ion conductor consists of an electrolyte which is filled in the cell separator, and a battery includes the ion conductor. A cell separator manufacturing method comprises a lithiation treatment step in which inorganic oxide fine particles capable of absorbing a liquid component are treated with a basic lithium reagent, a step in which the inorganic oxide fine particles, after being treated in the lithiation treatment step, are dispersed in a base material containing a high polymer substrate to obtain a dispersion composition, and a step in which the dispersion composition thus obtained is formed into shape. An ion conductor manufacturing method includes a step of filling the cell separator with an electrolyte. A battery manufacturing method includes a step of manufacturing the ion conductor. |
