▎ 摘  要

NOVELTY - The ion-conducting membrane (10) has a homogeneous blend of PBI with polymers selected from the group consisting of polyvinylidene difluoride (PVDF), PVDF-HFP, chitosan, and functionalized-chitosan. A mass- percentage of the polymers is in a range from 1 % to 40%. The additives are selected fiom the group consisting of graphene-oxide, functionalised graphene-oxide and h-BN. The mass percentage of the additives is in a range from 0.5 % to 80 %. The additives are dispersed in the homogeneous blend with a dispersion quantity greater than 80% and agglomeration quantity less than 30% and an area- specific ion-conductance of the ion-conducting membrane is greater than 1 S/cm2 at 30 degrees C. USE - Ion-conducting membrane useful in energy-generation, energy- conversion, and energy-storage. ADVANTAGE - The ion-conducting membrane has an area-specific ion conductance of greater than 1 S/cm 2 at 30 degrees C. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) a component comprising ion-conducting membrane; (2) a process for making ion-conducting membrane; (3) a process for making component ; and (4) a manufactured article.
