Summary: The rapid growth of the electric vehicle market has driven the development of lithium-ion batteries. Researchers are investigating Co-free and Ni-rich cathodes, such as LiNiO2, and Si anodes to meet the demand for high-energy-density and low-cost batteries. However, challenges with LiNiO2, such as cation mixing and safety risks, hinder its commercialization. Increasing the oxygen partial pressure during the calcination process of LiNiO2 has been found to improve its structural and electrochemical performance. This study proposes a mechanism by which the calcination oxygen partial pressure affects LiNiO2 and demonstrates that this strategy can enhance the performance of lithium-ion batteries.

Summary: Solid-state lithium metal batteries (SSLMBs) using high-nickel layered cathode of LiNi 0.8 Co 0.15 Al 0.05 O 2 (NCA) combined with solid polymer-based electrolyte (SPE) have attracted researchers' interest. However, the physical contact between NCA cathode and solid electrolyte is insufficient, leading to high contact resistance and non-uniform delithiation/lithiation kinetics. A design strategy of modifying the NCA surface with a fast ion-transport interlayer is proposed to enhance the ion-transport kinetics and improve the practical application of SSLMBs.

Summary: In this study, a concentration-gradient niobium-doping strategy was used to modify single-crystal LiNi0.83Co0.12Mn0.05O2 cathode. The Nb-rich surface acted as an electrochemically active protective layer against electrolyte corrosion, while the Nb-deficient core contributed to a higher capacity.

Summary: Low electrolyte/sulfur ratio is an important factor in increasing the energy density of lithium-sulfur batteries. By using catalytic hosts to suppress the shuttle effect, the E/S has been widely lowered. However, the shelf-life of these cathodes has not been studied. Our research reveals that the adsorption strength of commonly-used catalytic hosts is critical for effectively hindering the disproportionation of polysulfides.

Summary: Domain boundaries are important active sites for electrochemical energy storage materials. Layered double hydroxides tend to grow into single crystalline nano sheets, but efforts have been made to design hierarchical structures to provide more exposed electroactive sites. In this study, low angle grain boundaries were introduced into flakes of Ni/Co layered double hydroxides, resulting in defect-rich nano flakes that self-assembled into hydrangea-like spheres. These spheres further constructed a hollow cage structure. The formation of hierarchical structure and grain boundaries was explained by the synergistic effect of the Ni2+/Co2+ ratio. The battery-type electrode material fabricated from the NiCo-LDH-2 showed significantly enhanced specific capacitance and energy density.

Summary: Novel iron-rich nitride nanoparticles with tunable electronic and bonding characteristics were designed and anchored on N-doped porous carbon for potential use in energy storage and conversion. The synergistic effects of phase transition and electron-spin regulation on oxygen electrocatalysis were demonstrated. The (CoxFe1-x)(3)N@NPC core-shell structure with high dispersibility was induced by an intermediate phase transition process, which effectively prevented the coarsening of metallic nitrides. The incorporation of cobalt regulated the spin polarization of d-band electrons, and the optimal cobalt content (Co0.17Fe0.83)(3)N@NPC showed improved bifunctional catalytic performances in balancing the adsorption of *O-2 and the hydrogenation of *OH.

Summary: This study constructs a multicomponent photocatalyst SrTiO3/NiO/NiS with p-n heterojunction and Schottky junction, inspired by the concepts of electrons transfer layer (ETL) and holes transfer layer (HTL) in perovskite solar cells, to convert solar energy into easily storable solar fuels. The combination of NiS and NiO, which function analogously to ETL and HTL, achieves the reverse migration of electrons and holes, leading to a noticeable enhancement in photocatalytic performance. The use of in situ irradiation X-ray photoelectron spectroscopy (ISI-XPS) provides a comprehensive elucidation of the catalytic mechanism and heterojunction formation process by tracking photogenerated charges migration pathways between microscopic heterogeneous interfaces, demonstrating the capability of ISI-XPS in directly and accurately tracking charge transfer pathways and serving as an intriguing highlight within the catalyst design strategy.
