Layered Ni‐rich lithium transition metal oxides are promising battery cathodes due to their high specific capacity, but their poor cycling stability due to intergranular cracks in secondary particles restricts their practical applications. Surface engineering is an effective strategy for improving a cathode's cycling stability, but most reported surface coatings cannot adapt to the dynamic volume...
Owing to the interacted anion and cation redox dynamics in Li2MnO3, the high energy density can be obtained for lithium‐rich manganese‐based layered transition metal (TM) oxide [Li1.2Ni0.2Mn0.6O2, LNMO]. However, irreversible migration of Mn ions and oxygen release during highly de‐lithiation can destroy its layered structure, leading to voltage and capacity decline. Herein, non‐TM antimony (Sb) is...
Well‐organized Si‐Cu nanocables are directly anchored on a current collector to promote the cycling stability and high rate capability of Si as a superior anode in lithium‐ion batteries.
