Abstract Ni‐rich Li[Ni x Co y Mn 1− − ]O 2 ( ≥ 0.8) layered oxides are the most promising cathode materials for lithium‐ion batteries due to their high reversible capacity of over 200 mAh g −1 . Unfortunately, anisotropic properties associated with α‐NaFeO structured crystal grains result in poor rate capability and insufficient cycle life. To address these issues, a micrometer‐sized LiNi 0.8 0.1 O secondary material consisting radially aligned single‐crystal primary particles is proposed...

Hard carbon (HC) as a potential candidate anode for sodium-ion batteries (SIBs) suffers from unstable solid electrolyte interphase (SEI) and low initial Coulombic efficiency (ICE), which limits its commercial applications urgently requires the emergence of new strategy. Herein, an organic molecule with two sodium ions, disodium phthalate (DP), was successfully engineered on HC surface (DP-HC) to replenish loss formation. A stabilized ultrathin (≈7.4 nm) SEI constructed DP-HC surface, proved...

Abstract Sodium‐ion batteries are in high demand for large‐scale energy storage applications. Although it is the most prevalent cathode, layered oxide associated with significant undesirable characteristics, such as multiple plateaus charge−discharge profiles, and cation migration during repeated cycling of Na‐ions insertion extraction, which results sluggish kinetics, capacity loss, structural deterioration. Here, a new strategy, i.e., manipulation transition‐metal ordering oxides, proposed...

Nickel-rich layered oxides (NLOs) exhibit great potential to meet the ever-growing demand for further increases in energy density of Li-ion batteries because their high specific capacities. However, NLOs usually suffer from severe structural degradation and undesired side reactions when cycled above 4.3 V. These effects are strongly correlated with surface structure chemistry active NLO materials. Herein, we demonstrate a preformed cation-mixed ( Fm3̅ m) nanolayer (∼5 nm) that shares...

Na-ion batteries (NIBs) are sustainable alternatives to Li-ion technologies due the abundant and widely-distributed resources. However, most promising cathode materials of NIBs so far, O3 layered oxides, suffer from serious air instability issues, which significantly increases manufactural cost carbon footprint because long-term use dry rooms. While some feasible strategies proposed via case studies, universal design for air-stable cathodes yet be established. Herein, degradation mechanisms...

Abstract All‐solid‐state lithium batteries (ASSBs) have received increasing attentions as one promising candidate for the next‐generation energy storage devices. Among various solid electrolytes, sulfide‐based ASSBs combined with layered oxide cathodes emerged due to high density and safety performance, even at high‐voltage conditions. However, interface compatibility issues remain be solved between cathode sulfide electrolyte. To circumvent this issue, we propose a simple but effective...

The debate about whether the insulating phases of vanadium dioxide ($\mathrm{V}{\mathrm{O}}_{2}$) can be described by band theory or it requires a strong electron correlations remains unresolved even after decades research. Energy-band calculations using hybrid exchange functionals including self-energy corrections account for metallic nature different but have not yet successfully accounted observed magnetic orderings. Strongly correlated theories had limited quantitative success. Here we...
