Abstract

This study involves the production of high-capacity nickel borideNickel borides (Ni4B3) electrodes via cathodic reduction and thermal diffusion-based boriding method (CRTD-Bor)CRTD-Bor. After 30 min of CRTD-BorCRTD-Bor at 1000 °C and 200 mA/cm2, 10 min of phase homogenization (the substrate was immersed in the electrolyte without any polarization) were applied to form stoichiometric Ni-boride structuresStructure. The electrochemical behaviors of the Ni-boride specimens were examined in a 6 M KOH solution by using a three-electrode system. The cyclic voltammetry experiments were conducted within a potential window of 0–0.45 V, up to 1500 cycles. The areal capacitance (Ca) values were calculated as ~60, 195, 262, and 295 mF/cm2 for the 5th, 500th, 1000th, and 1500th cycles, respectively.
