Figure 6. (A) The XRD scan of SS-0.1 and SS-1 after the cycles of charge/discharge. (B) the ICP-MS results of SS-0.1 and SS-1 after 2,000 cycles of charge/discharge. (C) XPS of CsPbBr3 electrode in SS-1 after 2,000 cycles of charge and discharge without etching process. (D) TEM of TBAPF6 covered CsPbBr3 crystal obtained from CsPbBr3 electrode after 2,000 cycles of charge and discharge.
