Zinc ion battery is now getting attention in energy storage field with its non-flammable, eco friendly properties came from the use of aqueous electrolyte. However, it shows weakness in voltage window and cyclability caused by electrolyte and electrode, respectively. In particular, poor cyclability problem is generally deemed to be a result of an anode, especially zinc metal. Therefore, improving the reversibility of zinc metal anode is now the trend of zinc ion battery field. In this point of view, we have tried to cover the zinc metal with the black phosphorous and it showed better cyclability as well as lowered overpotential during operating. Synthesis was verified by the SEM, contack angle, XPS depth profile and. The growing process was analyzed with in-situ optical microscopy image. |
