A facile synthetic route based on the assistance of magnetic field is reported to fabricate core-shell CoB@Co(OH)(2) nanochains for purpose of high conductivity and enhanced pseudocapacitance in 3 M LiOH electrolyte. The typical core-shell CoB@Co(OH)(2) possesses suitable pore volume and high accessible electrode/electrolyte interfacial area, which allows for fast ion transport and rapid electron transfer. The CoB@Co(OH)(2) nanochains exhibit high specific capacitance and good cyclic stability, suggesting their potential energy application in alkaline electrolyte.
A facile synthetic route based on the assistance of magnetic field is reported to fabricate core-shell CoB@Co(OH)(2) nanochains for purpose of the high conductive pathway and enhanced pseudocapacitance in 3 M LiOH electrolyte. By adjusting the loading amount of the shell Co(OH)(2) nanosheets anchored on the core CoB alloy surface, the typical core-shell CoB@Co(OH)(2) is endowed with the appropriate pore volume of 0.27 cm(3) g(-1) and the high accessible electrode/electrolyte interfacial area (62.3 m(2) g(-1)) and the fast conductive highway; meanwhile taking advantages of core-shell structure can be favor for fast ion transport between the electrode/electrolyte interphase and rapid electron transfer. Benefiting from the advantageous properties, the typical CoB@Co(OH)(2) electrode exhibits a high specific capacitance of 492.8 F g(-1) in three-electrode device together with good cyclic stability (90.4% capacitance retention) during continuously 5000 cycles at 2 A g(-1). This work can provide an inspiring strategy for rational designing of core-shell CoB@Co(OH)(2), and indicate their potential energy application in alkaline electrolyte. [GRAPHICS] .
