文摘

β-Ni(OH)2 samples are synthesized using co-precipitation method. Electrochemical execution of β-Ni(OH)2 was examined utilizing CV and EIS studies. Reversibility of β-Ni(OH)2 electrode prolonged by zinc additive. Variation of pH was changing the charge transfer resistance and capacitance. Determine the capacitance of electrode by EIS study by using fitted circuit.
