Summary: The utilization of lithium (Li) metal as an anode for high energy density batteries is highly desirable, but is hindered by issues such as Li dendritic growth and inactive Li. The solid electrolyte interphase (SEI) layer plays a critical role in preventing direct contact between the electrolyte and the electrode, yet the formation mechanisms for SEI are not well understood. However, a strategic artificial SEI achieved through additives in the electrolyte can suppress Li dendrites and improve battery performance.

Summary: A key challenge in lithium-ion batteries is the instability of electrolytes against anode materials, with the solid-electrolyte interphase (SEI) providing stability at the cost of capacity consumption. Artificial SEIs offer more flexibility to tune properties such as chemical composition and impedance, but must ensure sufficient transport properties for Li-ions and stability.

Summary: This study investigates the effect of temperature on the solvation structure of lithium ions, revealing that increasing temperature enhances the interaction between lithium ions and anions, while weakening the interaction with solvents. This leads to changes in the interfacial chemistry, forming a solid electrolyte interphase (SEI) dominated by anions. However, at high temperatures, solvents tend to be reduced, resulting in an increase in organic species in the interphase. The temperature-responsive solvation structure and thermal reduction enable lithium ions to exhibit super-fast rate performance and high capacity retention at 25 degrees C.

Summary: Lithium (Li) metal is a promising candidate for high-energy batteries. In this study, a controllable dual-layer solid electrolyte interphase (SEI) is constructed to protect the Li metal anode and improve the electrochemical performance. The self-induced dual-layered SEI consists of a predeposited LiAlO2 (LAO) layer, which results in the reduction of electrolyte and the formation of an outer organic layer. The robust inner LAO layer promotes uniform Li deposition while the outer organic layer improves the stability of SEI.

Summary: To construct high-energy-density silicon-based Li-ion batteries, it is crucial to optimize and build a robust solid electrolyte interphase (SEI) to overcome the severe side reactions caused by volume changes in silicon (Si) anodes. This study combines electrolyte design and surface modification to create a phenyl trifluoromethanesulfonimide (PTFSI) interfacial layer on the Si surface, with additive functions. The resulting customized PTFSI interfacial layer modulates the solvation/desolvation reaction mechanism at the electrode interface, forming an artificial SEI structure composed of oligomers and inorganic salts. This structure exhibits fast ionic conductivity, reduces electrolyte consumption, and maintains the integrity of the electrode structure, leading to significantly improved rate capability and cycling performance of the optimized Si@PTFSI anode.

Summary: Laser pump X-ray Transient Absorption (XTA) spectroscopy has been enhanced with two new XTA data acquisition techniques: HRR-XMP and AXMP. HRR-XMP utilizes high repetition rate laser to increase data collection efficiency at each time delay. AXMP uses a frequency mismatch between laser and x-ray pulses to acquire XTA data at flexible pump-probe time delays. Both techniques have been successfully demonstrated in measuring laser-induced spectral dynamics of aqueous solutions of Fe(CN)(6)(4-) and [Fe-II(bpy)(3)](2+).

Summary: Metal boride nanostructures have great potential for hydrogen storage applications. However, their synthesis is challenging due to high surface energy, strong bonding, and difficult surface termination. Mechanochemical exfoliation of magnesium diboride in zirconia produces ultrathin MgB2 nanosheets with high yield. High-pressure hydrogenation and dehydrogenation of these nanosheets reveal a hydrogen capacity 50 times larger than bulk MgB2. The enhancement is attributed to defective sites created by ball-milling and incomplete Mg surface coverage. The exfoliation and creation of ultrathin layers offer a promising direction for high-capacity hydrogen storage.

Summary: Due to environmental and physical factors, the C-V2X wireless communication network connection is prone to intermittent interruptions. This can lead to deterioration in the performance of vehicle platooning, as the vehicles are unable to receive necessary information. To address this issue, a robust control method based on the intermittent information connection of the leading vehicle through the C-V2X communication network is proposed. The designed platoon control strategy, based on the mode-dependent average dwell time method, improves conservatism and flexibility compared to the average dwell time method. The method is also applicable to various communication topologies, and its effectiveness is verified through simulation.

Summary: Metal anodes are highly desirable for next-generation batteries due to their high capacity and low potential. However, challenges such as dendrite growth and volume change hinder their practical applications. This study demonstrates the use of organic and inorganic hybrid interfaces to achieve stable electrochemical performance for Li- and Na-metal anodes. The optimized thicknesses of the nanoalloy interfaces differ for Li- and Na-metal anodes, and the mechanical stability of the interfaces influences the electrochemical performance. This research establishes a fundamental understanding and connection between mechanical properties and electrochemical performance for alkali-metal anodes.

Summary: Over the past decade, the development of layered-hydroxide-based self-supporting electrodes has faced limitations due to the low active mass ratio. However, this study breaks the intrinsic limit by engineering F-substituted beta-Ni(OH)(2) plates with a sub-micrometer thickness, achieving a superhigh mass loading on the carbon substrate. Through theoretical calculation and analysis, it is found that NH4+ and F- synergistically modulate the sub-micrometer-thickness 2D plates, leading to promising applications in energy storage.

Summary: This study demonstrates the measurement of the interface between Li metal and the solid electrolyte LiPON using neutron reflectometry and in situ electrochemistry, which confirms the presence of a thin interphase less than 7 nm thick. The interphase is found to be a chemical gradient consisting of a Li-rich layer that gradually blends into pure LiPON. The ability to create ideal solid-solid interphases thinner than 10 nm holds significant importance in facilitating the adoption of high efficiency next generation solid state batteries, as well as providing a more general methodology for studying buried solid-solid interfaces across applications.

Summary: In this study, theoretical models were constructed by incorporating Fe-TCPP and Fe-(mIM)(n) (n = 2,3,4) active sites into hole-graphene and their structural stability was assessed through molecular dynamics simulations. The oxygen reduction reaction (ORR) mechanism and the effects of spatial confinement and ligands were systematically investigated using DFT calculations. The analysis revealed that Fe-TCPP and Fe-(mIM)(4) exhibit good catalytic activity. Additionally, the introduction of confinement effect (5-14 angstrom) demonstrated its influence on catalytic activity, with the lowest overpotential observed at an axial space of 8 angstrom for Fe-TCPP and 9 angstrom for Fe-(mIM)(4). Four ligands (bpy, pya, CH3, and bIm) were selected to explore their impact on the catalytic activity of Fe-TCPP, and modifications with bpy, pya, and bIm_N resulted in a decrease of 26-31% in overpotential. The best catalytic system identified in this work was Fe-TCPP_pya, which occupied the top position in the volcano plot.
