摘要：
A novel P2-type Na2/3Ni1/6Mg1/6Ti2/3O2 material is explored as an anode for sodium-ion batteries (SIBs) for the first time. It delivers a reversible capacity of 92 mA h g(-1) with a safe average storage voltage of approximately 0.7 V in a sodium half-cell, and exhibits good cycle stability (ca. 87.4% capacity retention for 100 cycles) at a cut-off voltage of 0.2-2.5 V, indicating its superiority as a promising candidate anode material for SIBs.
