Because of their layered framework and high theoretical capability, bismuth chalcogenides have already been proposed as anodes inside organic electrolyte Li- and Na-ion batteries. On the other hand, their particular electrochemical properties in aqueous systems have not been reported. Here, the electrochemical performance of Bi2Se3 thin films in 1 Michael NaNO3 aqueous electrolyte is usually presented. This aqueous Bi2Se3 system was found to get up to two purchases of magnitude increased durchmischung coefficients, compared to additional anode materials in Na electrolyte-based systems, as good as limited anode electrode degradation over 5 CVs and significant changes inside the anode after thirty CVs.
