💡 Novelty & Significance:
Near-micron single-crystalline δ-DRX cathodes achieve ~640 Wh/kg with 97% retention over 400 cycles. Novelty: identifying interparticle compositional heterogeneity as the origin of LiMnO₂ impurity, enabling accelerated cooling that suppresses impurities and downsizes particles. Significance: a mechanistic basis for particle-size control in Mn-rich DRX synthesis, advancing sustainable, high-performance, Ni- and Co-free Li-ion cathodes.
