Rational design of promising electrolyte is considered as an effective strategy to improve the cycling stability of lithium metal batteries (LMBs). Here, an elaborately designed ionic liquid‐based electrolyte is proposed that is composed of lithium bis(trifluoromethanesulfonyl)imide as the lithium salt, 1‐ethyl‐3‐methylimidazolium nitrate ionic liquid ([EMIm][NO3] IL) and fluoroethylene carbonate (FEC) as the functional solvents, and 1,2‐dimethoxyethane (DME) as the diluent solvent. Using [EMIm][NO3] IL as the solvent component facilitates a special Li+‐coordinated NO3− solvation structure, which enables the continues electrochemical reduction of solvated NO3− and the formation of remarkably stable and conductive solid electrolyte interface. With FEC as another functional solvent and DME as the diluent solvent, the formulated electrolyte delivers high oxidative stability and ionic conductivity, and endows improved electrochemical reaction kinetics. Therefore, the formulated electrolyte demonstrates exceedingly reversible and stable Li stripping/plating behavior with high average Coulombic efficiency (98.8%) and ultralong cycling stability (3500 h). Notably, the high‐voltage Li|LiNi0.8Co0.1Mn0.1O2 full cell with IL‐based electrolyte exhibits enhanced cyclability with a capacity retention of 65% after 200 cycles under harsh conditions of low negative/positive ratio (3.1) and lean electrolyte (2.5 µL mg−1). This study creates the first NO3−‐based ionic liquid electrolyte and evokes the avenue for practical high‐voltage LMBs. [ABSTRACT FROM AUTHOR]

Glucose oxidase (GOD)‐based starvation therapy (ST), which inhibits the growth and proliferation of cancer cells by consuming glucose, has attracted intensive attention as an emerging non‐invasive method for fighting cancers. However, the enzyme activity of GOD is greatly limited in vivo because of its optimal catalytic activity in the temperature range of 43–60 °C. Herein, a photothermal‐enhanced starvation strategy is developed based on our engineered organosilica hybrid micelles (TiO2‐x@POMs‐GOD), in which the fluoride‐doped TiO2‐x with photothermal properties is encapsulated in the cores of organosilica cross‐linked micelles and GOD is immobilized on the carboxyl groups of PAA segments. With its internalization by cancer cells, the conjugated GOD can effectively deplete glucose to achieve the ST effect, which can be remarkably enhanced by the loaded fluoride‐doped TiO2‐x with NIR laser irradiation, thus cooperatively contributing to the efficient treatment of TiO2‐x@POMs‐GOD on various cancer cells. This suggests great potential for TiO2‐x@POMs‐GOD in photothermal‐enhanced ST in vivo. [ABSTRACT FROM AUTHOR]
