Title:
TWO-DIMENSIONAL NI-ORGANIC FRAMEWORK/RGO COMPOSITE AND ELECTRODE FOR SECONDARY BATTERY OR SUPER-CAPACITOR COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2021/091323
Kind Code:
A1
Abstract:
The present invention relates to a two-dimensional Ni-organic framework/rGO composite comprising: a two-dimensional electroconductive Ni-organic framework in which Ni and an organic ligand containing a substituted or unsubstituted C6-C30 aryl-hexamine are repeatedly bonded in a branched form; and reduced graphene oxide (rGO). Thus, when a composite of reduced graphene oxide (rGO) and two-dimensional Ni-MOF is prepared and used as an energy storage electrode material, the two-dimensional Ni-organic framework/rGO composite of the present invention can exhibit higher discharge capacity per weight due to the synergistic effect of rGO and Ni-MOF as compared to when Ni-MOF is used alone, and the composite is used to manufacture a thin-film-type electrode, which can be used as a next-generation energy storage electrode having mechanical bending strength and high energy density per volume.
