Abstract

Abstract : In article number 2000135, Jinli Zhang, Xiao‐Guang Sun, Sheng Dai and co‐workers report a F‐substitution strategy for a P2‐type sodium oxide cathode (Na2/3 Ni1/3 Mn2/3 O2− x F x ), which not only enhances its Na + diffusion coefficients and specific discharge capacity, but also improves its long‐term cycling stability by suppression of the biphasic reaction in the low voltage range.
