In summary, this study demonstrates that intralattice-bonded phase engineering provides a mechanistic route to stabilize ultrahigh-Ni single-crystalline cathodes via direct modulation of lattice-scale strain evolution. Such a strategy complements conventional morphology-based approaches, revealing that structural integrity can be enhanced not only at the particle level but also at the lattice scale. Consequently, IBP engineering emerges as a rational and adaptable design principle for stabilizing next-generation high-energy cathode materials and enabling durable, high-performance lithium-ion batteries.
