Abstract Understanding and modulating the unique electronic interaction between single‐metal atoms high entropy compounds are of great significance to enable their high‐efficiency oxygen electrocatalysis for aprotic lithium‐oxygen (Li‐O 2 ) batteries. Herein, a novel bi‐functional electrocatalyst is first time created by immobilizing single‐atom ruthenium (Ru) on lanthanum‐based perovskite oxide La(Mn 0.2 Co Fe Ni Cr )O 3 (Ru@HEPO), which demonstrates activity stability in Li‐O The heteronuclear coordination Ru HEPO facilitates fast electron transfer from establishing Ru‐O‐M (M stands Mn, Co, Fe, Ni) bridges, well redistributes electrons within Ru@HEPO hence significantly improving its interfacial charge kinetics electrocatalytic activity. Additionally, strong coupling Mn enhances hybridization 3d O 2p orbitals, promotes inherent affinity toward LiO intermediate, thereby reducing reaction energy barrier electrode. As result, Ru@HEPO‐based batteries deliver remarkable electrochemical performances, such as efficiency (87.3% at 100 mA g −1 ), excellent rate capability (low overpotential 0.52 V durable cyclability (345 cycles 300 ). This work opens up promising avenue development entropy‐based electrocatalysts precisely tailoring distributions an atomic scale.

Lithium (Li) metal batteries (LMBs) with nickel (Ni)-rich layered oxide cathodes exhibit twice the energy density of conventional Li-ion batteries. However, their lifespan is limited by severe side reactions caused high electrode reactivity. Fluorinated solvent-based electrolytes can address this challenge, but they pose environmental and biological hazards. This work reports on molecular engineering fluorine (F)-free ethers to mitigate surface reactivity in high-voltage Ni-rich LMBs. By merely extending alkyl chains traditional ethers, we effectively reduce catalytic cathode towards electrolyte at voltages, which suppresses oxidation decomposition electrolyte, microstructural defects rock-salt phase formation cathode, gas release issues. The NCM811-Li battery delivers capacity retention 80 % after 250 cycles a Coulombic efficiency 99.85 %, even superior that carbonate electrolytes. Additionally, strategy facilitates passivation Li anode forming robust solid-electrolyte interphase, boosting reversibility 99.11 cycling life 350 cycles, outperforms F-free ether Consequently, practical LMBs has been prolonged over 100 500 compared those carbonate- ether-based electrolytes, respectively.
