                      White (PW) Na-ion cathodes to address the issue of
                      unfavorable multilevel phase transitions upon
                      electrochemical cycling, leading to poor stability and
                      capacity decay. A series of Mn-based samples with up to six
                      metal species sharing the N-coordinated positions was
                      synthesized. The material of composition

                      was found to exhibit superior cyclability over
                      medium/low-entropy and conventional single-metal PWs. We
                      also report, to our knowledge for the first time, that a
                      high-symmetry crystal structure may be advantageous for
                      high-entropy PWs during battery operation. Computational
                      comparisons of the formation enthalpy demonstrate that the
                      compositionally less complex materials are prone to phase
                      transitions, which negatively affect cycling performance.

                      techniques, an intrinsic mechanism for the stability
