Peroxo formation is the crucial step in oxygen redox. In their Research Article on page 10056, Bjoern Schwarz, Xiao Cheng Zeng, Jun Li, and co‐workers report on the reversible peroxo species formed and confined in high‐capacity silicate cathodes. The picture shows the dominating binding mode of peroxo species, which forms in the delithiation amid high‐voltage charging and reverses in the lithium re‐intercalation during discharging. The reversible oxygen transformation following cationic redox is promising for high‐energy, high‐safety lithium‐ion batteries.
