Aiming to prepare supercapacitor electrode materials,a new selenite Co0.8 Ni0.7-(OH)SeO3 was synthesized via a facile chemical approach.The morphology and composition of the products as-obtained were characterized by various test techniques,in detail.In addition,the impedance and electrochemical property of the products were studied by electrochemical impedance spectroscopy and cyclic voltammetry,respectively.Significantly,the charge-discharge test results showed that the Co0.8 Ni0.7(OH)SeO3 exhibited high ...
