Polyurea electrolyte and method for manufacturing the same

摘要

A polyurea electrolyte includes a polyurea resin formed by a polymerization of a first compound having two or more isocyanate groups and a second compound having two or more amino groups. The first compound or the second compound contains ten or more carbon chains, and the first compound or the second compound contains a sulfonic acid group or a carboxylic acid group. A method for manufacturing the polyurea electrolyte includes neutralizing the sulfonic acid group or the carboxylic acid group in the first compound or the second compound by a neutralizing agent; after the neutralizing, polymerizing the first compound and the second compound; and after the polymerizing, removing the neutralizing agent from a polymer of the first compound and the second compound.

主权项

1. A polyurea electrolyte, comprising:
a polyurea resin formed by polymerizing a first compound having two or more isocyanate groups and a second compound having two or more amino groups, the first compound containing ten or more carbon chains, and the second compound containing a sulfonic acid group or a carboxylic acid group, wherein the first compound is one of the following (a) to (d) compounds: (a) a compound in which both terminals of conjugated diene glycol or a hydrogenated substance thereof are substituted by an isocyanate group; (b) a compound in which both terminals of vegetable oil containing a hydroxyl group, a carboxylic acid group or an amine group are substituted by an isocyanate group; (c) a compound in which a carboxylic acid group or an amine group in vegetable oil containing a carboxylic acid group or an amine group is substituted by an isocyanate group; and (d) dimer acid diisocyanate.
