High-capacity power battery can be attained through the elevation of cut-off voltage for LiNi0.83Co0.12Mn0.05O2 high-nickel material. Nevertheless, unstable lattice oxygen would released during lithium deep extraction. To solve above issues, electronic structure is reconstructed by substituting Li+ ions with Y3+ ions. The dopant within Li layer could transfer electrons to adjacent oxygen. Subsequently, accumulated in site are transferred nickel highly valence state under action reduction coupling mechanism. modified strategy suppresses generation defects regulating local structure, but more importantly, it reduces concentration reactive Ni4+ species charging state, thus avoiding evolution an unexpected phase transition. Strengthening strength between layers and transition metal finally realizes fast-charging performance improvement cycling stability enhancement high voltage. Authors report on restructuring a material This mechanism improving high-voltage stability.

ABSTRACT Although lithium‐ion batteries (LIBs) have found an unprecedented place among portable electronic devices owing to their attractive properties such as high energy density, single cell voltage, long shelf‐life, etc., application in electric vehicles still requires further improvements terms of power better safety, and fast‐charging ability (i.e., 15 min charging) for driving range. The challenges fast charging LIBs limitations low transport the bulk solid electrode/electrolyte interfaces, which are mainly influenced by ionic conductivity electrolyte. Therefore, electrolyte engineering plays a key role enhancing capability LIBs. Here, we synthesize novel propionic acid‐based viologen that contains 4,4′‐bipyridinium unit terminal carboxylic acid group with positive charges confine PF 6 ‒ anions accelerate migration lithium ions due electrostatic repulsion, thus increasing overall rate capability. LiFePO 4 /Li cells 0.25% added show discharge capacity 110 mAh g ‒1 at 6C 95% retention even after 500 cycles. not only enhances electrochemical properties, but also significantly reduces self‐extinguishing time.

Abstract Silicon (Si) holds immense promise as viable anode for next‐generation high‐energy‐density Li‐ion batteries (LIBs). However, its poor ionic/electronic conductivity and significant volumetric changes during cycling lead to rapidly deteriorated LIB performance. Here, a novel multifunctional coating featuring ultrafine SiO 2 nanoparticles (<7 nm) embedded carbon on Si (termed Si@uSiO ‐C) resolve these challenges is proposed. This unique uSiO ‐C provides high‐efficient electron ion transport pathways, while also improves interfacial stability mitigates volume cycling, thereby enhancing the structural integrity of ‐C, corroborated by extensive experimental computational studies. In addition, abundant interfaces in facilitate Li + evenly distributed impart high electrochemical reactivity mechanical robustness. Consequently, achieves reversible capacity 2093 mAh g −1 at 0.2 A , with initial Coulombic efficiency 88.3%, superior rate capability durability (1000 cycles, 928 1.0 75% retention). Full cells paired commercial LiFePO 4 cathodes demonstrate cyclability, maintaining 80% retention over 500 cycles C. work highlights vital role promoting performance Si‐based anodes high‐performance LIBs.
