<p>Perovskite fluorides with three-dimensional skeletal structures have received extensive attention due to their high theoretical capacity as battery anodes. However, wide bandgap-induced low electronic conductivity and sluggish lithium-ion transport hinder their electrochemical reversibility. Herein, taking perovskite fluorides NaMF₃ (M from Mn, Ni, Co, Mg, Fe) as the research object, an entropy-mediated strategy is proposed to fundamentally enhance the carrier transport kinetics and electrochemical stability. Theoretical calculations show that the increased configurational entropy of NaMF₃ can induce the transformation from insulator or semiconductor or half-metal to metal conductor, thereby greatly improving electronic conductivity. Moreover, the high-entropy NaMF₃ anode exhibits outstanding lithium-ion diffusion kinetics with significant pseudocapacitive reaction characteristics due to abundant active sites and expandable unit cell volume. Therefore, high-entropy NaMF₃ anode demonstrates outstanding lithium storage performance with a high reversible capacity of 571 mAh g^-1 at 0.1 A g^-1, superior rate capability of 266 mAh g^-1 at 3.2 A g^-1, and predominant cycle stability of 165 mAh g^-1 after 1000 cycles at 2.0 A g^-1. Importantly, the lithium storage conversion mechanism and corresponding electrochemical contribution of metal elements have been elucidated for high-entropy NaMF₃ anode. This work provides a new idea for designing perovskite fluorides as lithium-ion battery materials.</p>
