Jahn–Teller Distortion Triggers Unconventional Molecular O 2 Formation in P2‐Type Na 0.67 MnO 2 Cathodes
Oxygen redox chemistry offers a pathway to high energy density in sodium‐ion batteries but is often accompanied by irreversible molecular O 2 formation, leading to voltage hysteresis and poor cycling stability. The origin of molecular O 2 formation is commonly attributed to high‐voltage charging yet remains deb...
