💡 Novelty & Significance:
This work pioneers selective Mo6+/Sr2+ doping to tune facet energetics, enabling [001]-oriented quasi-single-crystal Li-rich cathodes. The spatially differentiated dopants couple enhanced Li+ transport with suppressed oxygen release, reducing lattice strain by 47.2% and boosting 5C capacity from 133.6 to 163.1 mAh g−1. This dual-regulation strategy significantly advances high-energy, stable Li-rich battery cathodes.
