High‐Entropy Phase Stabilization Engineering Enables High‐Performance Layered Cathode for Sodium‐Ion Batteries (Adv. Energy Mater. 23/2024)

Sodium-Ion Batteries In article number 2401090, Xiaogang Wang, Xiaofan Du, Guanglei Cui, and co-workers present a zero-strain layered cathode for sodium-ion batteries by high-entropy phase stabilization engineering. This work not only addresses the drastic volumetric strain and cycling instability concerns for O3-type cathode materials but also elucidates the elemental functions in the high-entropy framework.
