3 /-- Hierarchical mesoporous graphene/Ni-Co-S array on 3-dimensional nickel foam composite and preparation method thereof

摘要

The present invention relates to a graphene / nickel-cobalt-sulfide array composite having a multi-layered mesoporous structure on a three-dimensional nickel foam and a method for producing the same. When the composite is used as an electrode, the storage capacity after only 2000 cycles is only 5.4% To exhibit excellent long-term cyclic stability, and in particular, the complex can be produced quickly and efficiently using a two-step process.;
