Lithium-metal batteries (LMB) employing cobalt-free layered-oxide cathodes are a sustainable path forward to achieving high energy densities, but these exhibit substantial transition-metal dissolution during high-voltage cycling. While crossover is recognized disrupt solid-electrolyte interphase (SEI) formation on graphite anodes, experimental evidence necessary demonstrate this for lithium-metal anodes. In work, advanced high-resolution 3D chemical analysis conducted with time-of-flight secondary-ion mass spectrometry (TOF-SIMS) establish spatial correlations between the transition metals and electrolyte decomposition products found cycled Insights into localization of various chemistries linked crucial processes that define LMB performance, such as lithium deposition, SEI growth, deposition deduced from precise elemental SEI. Heterogenous perpetuate both heterogeneous growth These confirmed across anodes different electrolytes. An stable higher voltages shown minimize its effects Overall, results highlight importance maintaining uniform coverage which disrupted by operation at voltages.

Abstract Ni‐rich LiNi 1− x − y Mn Co O 2 (NMC) layered oxides are promising cathode materials for high‐energy density lithium ion batteries but suffer from severe capacity fading upon cycling. Elemental substitution (= doping) with Mg has repeatedly attracted attention in NMC to overcome instability problems at reasonable cost, yet rational compositional tuning is needed guarantee sufficient cycle life without compromising energy on the material level. Herein, a series of Mg‐substituted 90 mol% Ni investigated regarding key performance metrics || graphite full‐cells benchmarked against 0.80 0.10 and 0.90 0.05 synthetized using same co‐precipitation route.

High-nickel LiNi1−x−yMnxCoyO2 and LiNi1−x−yCoxAlyO2 cathodes are receiving growing attention due to the burgeoning demands on high-energy-density lithium-ion batteries. The presence of both cobalt manganese in them, however, triggers multiple issues, including high cost, toxicity, rapid surface deterioration, severe transition-metal dissolution. Herein, a Co- Mn-free ultrahigh-nickel LiNi0.93Al0.05Ti0.01Mg0.01O2 (NATM) cathode that exhibits 82% capacity retention over 800 deep cycles full cells, outperforming two representative high-Ni LiNi0.94Co0.06O2 (NC, 52%) LiNi0.90Mn0.05Co0.05O2 (NMC, 60%) is presented. It demonstrated titanium-enriched along with aluminum magnesium as stabilizing ions NATM not only ameliorates unwanted side reactions electrolyte structural disintegrity, but also mitigates dissolution active lithium loss graphite anode. As result, anode paired displays an ultrathin (≈8 nm), monolayer anode-electrolyte interphase architecture after extensive cycling. Furthermore, considerably enhanced thermal stability elevated exothermic temperature (213 °C for vs 180 190 NC NMC, respectively) remarkably reduced heat release. This work sheds light rational compositional design adopt ultrahigh-Ni lithium-based batteries low long service life, improved stability.

Recent progress in high-energy-density oxide cathodes for lithium-ion batteries has pushed the limits of lithium usage and accessible redox couples. It often invokes hybrid anion- cation-redox (HACR), with exotic valence states such as oxidized oxygen ions under high voltages. Electrochemical cycling extreme conditions over an extended period can trigger various forms chemical, electrochemical, mechanical, microstructural degradations, which shorten battery life cause safety issues. Mitigation strategies require in-depth understanding underlying mechanisms. Here we offer a systematic overview functions, instabilities, peculiar materials behaviors cathodes. We note unusual anion cation mobilities caused by high-voltage charging valences. explains extensive lattice reconstructions at room temperature both good (plasticity self-healing) bad (phase change, corrosion, damage) senses, intriguing electrochemomechanical coupling. The insights are critical to self-healing phenomena ceramics (e.g., grain boundary sliding microcrack healing) novel cathode designs degradation mitigations suppressing stress-corrosion cracking constructing reactively wetted coating). Such mixed ionic-electronic conducting, electrochemically active oxides be thought almost "metalized" if voltages far from open-circuit voltage, thus differing significantly highly insulating ionic electronic transport mechanical behaviors. These characteristics should better understood exploited high-performance energy storage, electrocatalysis, other emerging applications.

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 High‐nickel layered oxide cathodes, such as LiNi 1‐ x ‐ y Mn Co O 2 (NMC) and Al (NCA), are at the forefront for implementation in high‐energy‐density lithium‐ion batteries. The presence of cobalt both cathode chemistries, however, largely deters their application due to fiscal humanitarian issues affiliated with sourcing. Increasing Ni content drives down content, but introduces additional structural electrochemical problems attributed high‐Ni cathodes. Herein a dually modified cobalt‐free ultrahigh‐nickel 0.02B‐LiNi 0.99 Mg 0.01 (NBM) is presented 1 mol% B that exhibits high initial 1C discharge capacity 210 mA h g −1 20% retention improvement over 500 cycles when benchmarked against LiNiO (LNO) pouch full cell configurations graphite anode. Postmortem analyses reveal enhanced performance stems from reduced active lithium inventory loss localized surface reactivity NBM cathode. stabilized cathode‐electrolyte interphase subsequently reduces transition‐metal dissolution ensuing chemical crossover anode, which prevents further catalyzed parasitic reactions harmfully passivate anode surface. Altogether, this study aims highlight importance electrode characterization analysis an interphasial viewpoint push ongoing research stabilize ultrahigh‐Ni cathodes industrial feasibility.
