[16] performed density functional theory (DFT) calculations on a variety of perovskite oxides and predicted theoretical overpotentials of …
This safety concern can be mitigated by embedding Pb in perovskite structure, which works as a reservoir for Pb metal ions for use in (de)alloying reaction based rechargeable batteries. Thus, we propose oxide perovskites as safe lead-based compounds capable of Pb-alloying reaction to yield high voltage, high energy density …
