| Abstract | Selenium (Se) is an appealing alternative cathode material for secondary battery systems that recently attracted research interests in the electrochemical energy storage field due to its high theoretical specific capacity and good electronic conductivity. However, despite the relevant capacity contents reported in the literature, Se-based cathodes generally show poor rate capability behavior. To circumvent this issue, we propose a series of selenium@carbon (Se@C) composite positive electrode active materials capable of delivering a four-electron redox reaction when placed in contact with an aqueous copper-ion electrolyte solution (i.e., 0.5 M CuSO4) and copper or zinc foils as negative electrodes. The lab-scale Zn | |Se@C cell delivers a discharge voltage of about 1.2 V at 0.5 A g(-1) and an initial discharge capacity of 1263 mAh g(Se)(-1). Interestingly, when a specific charging current of 6 A g(-1) is applied, the Zn | |Se@C cell delivers a stable discharge capacity of around 900 mAh g(Se)(-1) independently from the discharge rate. Via physicochemical characterizations and first-principle calculations, we demonstrate that battery performance is strongly associated with the reversible structural changes occurring at the Se-based cathode. Aqueous battery Se-based cathodes are based on a two-electron transfer electrochemical reaction and generally show inadequate rate capability behaviour. Here, the authors propose a four-electron Se chemistry with copper ions as charge carriers to enable fast-charging battery cycling. |
