To address these challenges, we propose a nano\u2010sol infusion doping strategy that overcomes the inherent limitations of conventional solid\u2010state doping, namely poor dopant homogeneity throughout secondary particles and particle agglomeration caused by high\u2010temperature calcination. This process enables nanoscale (\u223c10\u00a0nm) dopant precursors to be uniformly infused into the cathode precursor using only a small amount of solvent and simple equipment, facilitating stable dopant incorporation and homogeneous distribution during subsequent calcination. The infusion\u2010doped LNO (ID\u2010LNO) synthesized by this approach delivered a capacity retention of 86.06% after 100 cycles at 1 C, outperforming both undoped and solid\u2010state doped LNO. The results clearly demonstrate that ID\u2010LNO possesses superior structural stability, characterized by the suppression of microcrack formation and mitigation of\n                    <jats:italic>c<\/jats:italic>\n                    \u2010axis contraction during the H2\u2013H3 phase transition. This study demonstrates that nano\u2010sol infusion doping is a novel synthesis strategy capable of fundamentally alleviating the structural degradation of LNO and suggests it as a viable approach with potential applicability to various high\u2010valence dopants and ternary layered oxide compositions (e.g., NCM and NCA) for the development of long\u2010life, high\u2010rate, and high\u2010energy\u2010density lithium\u2010ion batteries.\n
