“…However, from the perspective of their redox activity, Mn4+ is difficult to be further oxidized, whereas Ru4+ is easily oxidized to Ru5+. Therefore, comparison of other Li-rich metal oxides that integrate Ni and a second TM with no further oxidation beyond 4+ (e.g., Zr4+ or Pd4+) will be valuable as they can form monoclinic Li 2 ZrO 3 ( C 2/ c ) 67 and Li 2 PdO 3 ( C 2/ m ) 68 , to the best of our knowledge, the electrochemistry of which are not well studied yet.…”

“…Recently, material explorations using computational screening have assisted in the identification of promising candidates using high-throughput material databases based on first principles calculations. [24][25][26][27] Promising materials were identified for coatings at the interface of solid electrolytes, 28,29 cathode materials, [30][31][32][33][34] anode materials, 35,36 solid-state electrolyte, 37 Mg battery electrolytes, 38 photo-catalysts, 39 and fuel cell electrodes. 40 Our earlier works also presented novel and promising anode materials for SIBs using high-throughput screening.…”

“…This result could be ascribed to the strong metallic character of Cd relative to that of Ir. As reported in previous research, the high covalence of the 5d TM‐O band would have a tendency to suppress O 2 release 2a,6,10a,13. To obtain further information, a comparison of the reaction energy for O 2 release was performed for the Ir, Ru, and Cd surfaces.…”
