Abstract Lithium metal batteries (LMBs) with Li anodes and high‐voltage LiCoO 2 (LCO) cathodes offer high energy density but face challenges such as dendrite growth LCO structure degradation, which primarily arises from the electrolyte's inability to form a stable interphase. Herein, dual‐additive optimized carbonate‐based electrolyte is developed, incorporating tetraethylammonium nitrate (TEANO 3 ) lithium difluorobis(oxalato) phosphate (LiDFBOP) regulators. LiDFBOP enhances interfacial stability compactness, while TEANO facilitates + transport suppresses excessive decomposition of LiDFBOP. The synergistic effect establishes robust, ion‐conductive solid interphase (SEI) cathode–electrolyte (CEI) enriched P‐ N‐containing inorganic compounds (including LiN x O y P‐O/P‐F species), enabling dense deposition cycling under cut‐off voltage 4.5 V. enables Li||LCO full cells capacity retention 84% even high‐mass‐loading cathode (3.5 mAh cm −2 limited (N/P = 2). This work demonstrates straightforward design strategy for optimizing SEI CEI, advancing practical deployment LMBs.

Abstract High‐voltage nickel (Ni)‐rich layered oxide‐based lithium metal batteries (LMBs) exhibit a great potential in advanced due to the ultra‐high energy density. However, it is still necessary deal with challenges poor cyclic and thermal stability before realizing practical application where cycling life considered. Among many improved strategies, mechanical chemical for electrode electrolyte interface plays key role addressing these challenges. Therefore, extensive effort has been made address of electrode‐electrolyte interface. In this progress, failure mechanism Ni‐rich cathode, anode electrolytes are reviewed, latest breakthrough stabilizing also summarized. Finally, future research directions LMBs put forward. image

Abstract Silicon anode is an appealing alternative to enhance the energy density of lithium‐ion batteries due its high capacity, but it suffers from severe capacity fade caused by fast degradation. The crossover dissolved transition‐metal (TM) ions cathode known catalyze decomposition electrolyte on graphite surface, relative impact Mn 2+ versus Ni Co silicon remains be delineated. Since all three TM can dissolve LiNi 1−x−y x y O 2 (NMC) cathodes and migrate anode, here a LiFePO 4 paired with SiO assess introducing specific amount or into electrolyte. It found that cause much larger increase in electrode thickness during cycling increased solid–electrolyte interphase (SEI) formation compared ions, similar previous findings anode. However, lower impedance, SEI formed protects Si excessive degradation ions. Thus, have less detrimental effect anodes than which opposite seen anodes.
