Co-Stabilization of High-Entropy Oxides by Entropy and Polyanionic Units toward High-Capacity Zero-Strain Anodes for Advanced Lithium-Ion Batteries.

ABSTRACT: High-entropy oxides (HEOs) have attracted considerable attention as anode materials for lithium-ion batteries, owing to their entropy-driven structural stabilization. However, practical deployment is often limited by rapid capacity fading and irreversible phase transitions during cycling. To overcome these challenges, a phosphorus doping strategy is introduced that incorporates stable PO₄ ^3- groups into the HEO lattice, resulting in a novel zero-strain anode material, denoted as [P_x(LiCrMnFeCoZn)_1-x]₃O₄ (PHEO). The PHEO anode delivers a high specific capacity of 686.2 mAh g^-1 at 0.5 A g^-1, along with exceptional cycling stability exhibits exceptional cycling stability, retaining 116.4% of its capacity a
