The Electrochemical Characterization of Nanostructured Bi<sub>2</sub>Se<sub>3</sub> Thin Films in an Aqueous Na Electrolyte
Due to their layered structure and high theoretical capacity, bismuth chalcogenides have been proposed as anodes in organic electrolyte Li- and Na-ion batteries. On the other hand, their electrochemical properties in aqueous systems have not been reported. Here, the electrochemical performance of Bi...

| description | Due to their layered structure and high theoretical capacity, bismuth chalcogenides have been proposed as anodes in organic electrolyte Li- and Na-ion batteries. On the other hand, their electrochemical properties in aqueous systems have not been reported. Here, the electrochemical performance of Bi<sub>2</sub>Se<sub>3</sub> thin films in 1 M NaNO<sub>3</sub> aqueous electrolyte is presented. This aqueous Bi<sub>2</sub>Se<sub>3</sub> system was found to have up to two orders of magnitude increased diffusion coefficients, compared to other anode materials in Na electrolyte-based systems, as well as limited anode electrode degradation over 5 CVs and significant changes in the anode after 30 CVs. |
