he Ni foam can act as the source of nickel ions and current collector for
synthesizingNi-based compounds using a hydrothermal reaction especially
in acid condition. Using Ni foam as the Ni
2+
source can grow materials on the
substrate directly and uniformly since nickel ions are released from substrate
thoroughly. Nickel-based bimetallic oxides are intensively investigated as
battery-type materials for battery supercapacitor hybrid devices (BSHD)
because of high electrical conductivities and abundant transition states for
inducing multiple redox reactions. In this study, Mo, Mn, Al, and W precursors
are simply added in Ni precursor-free acid solution for hydrothermal reaction
using nickel foam as source of nickel ions and current collector to synthesize
Ni-based bimetallic oxide electrodes for BSHD. The morphology of nickel-
based bimetallic oxide prepared with and without incorporating structure-
directing agent is also carefully discussed. The highest specific capacitance
