MULTILAYER MESOPOROUS GRAPHENE/NICKEL-COBALT-SULFIDE ARRAY COMPOSITE ON THREE-DIMENSIONAL NICKEL FOAM AND PREPARATION METHOD THEREOF

摘要

The present invention relates to a multilayer mesoporous graphene/nickel-cobalt-sulfide array composite on a three-dimensional nickel foam and a preparation method thereof. If the composite is used as an electrode, an energy accumulation capacity is reduced only by 5.4% after being used 2,000 times. Accordingly, the composite shows excellent long-term circulation stability and can be rapidly and effectively manufactured by using a two-step method.;COPYRIGHT KIPO 2017
