Summary: The SiOx@Si-FeSi2 nanocomposite, synthesized with a novel double-protection strategy for Si, exhibits high cycling performance and good rate capability in high-power LIBs. The excellent electrochemical performance of this material is mainly attributed to the well-dispersed active Si in the FeSi2 phase and the SiOx core-shell structure that reduces mechanical stresses/strains on Si during lithiation/delithiation processes.

Summary: The theoretical study compared the capabilities of self-passivated porous phosphorene and perfect phosphorene nanosheet as anode materials in fast rechargeable Li/Na ion batteries. The creation of nanopores inside the perfect phosphorene nanosheet led to increased band gap and higher susceptibility to absorb Li/Na atoms, with enhanced adsorption energy around the pores. Storage capacities of porous phosphorene were calculated to be lower than perfect phosphorene, with a significant charge transfer needed for electrical conductivity as an anode material.

Summary: In this study, a vanadium dioxide/ graphene oxide (VO2(B)/GO) sample was constructed through hydrothermal route, which exhibited remarkable rate capability. The presence of oxygen vacancies in VO2(B)/GO weakened the electrostatic force, while GO prevented vanadium oxidation. The electrode showed a high reversible capacity of 423 mAh g-1 at 0.5 A g-1 and maintained long-life cycling properties at 15 A g-1. The combination of oxygen vacancies and GO contributed to excellent performance and prevented the collapse of VO2 structure during cycling. VO2(B)/GO also exhibited excellent performance in all-climate conditions (-15-60 degrees C).

Summary: In this study, a charge-transfer complex electrolyte additive, 7,7,8,8-tetracyanoquinodimethane (TCNQ), with high affinity for zinc was used to form a dense and robust interfacial complex layer on the zinc anode, suppressing the activity of H(2)O. The complex layer enabled the formation of a Zn-Zn-(TCNQ)(2) Ohmic contact interface, facilitating rapid ion/electron transport, improving electric field distribution, and preventing direct contact between active H2O and the zinc anode, resulting in a dendrite-free zinc anode and efficient zinc plating/stripping kinetics. As a result, the Zn||Zn symmetrical cell exhibited high plating/stripping reversibility for over 1000 hours at 20 mA cm(-2) and 5 mA h cm(-2), and a high depth of discharge of 43%. Furthermore, the Zn||MnO2 full cell demonstrated a high capacity of 143.3 mA h g(-1) at 2000 mA g(-1) even after 4000 cycles, with a capacity retention of 94.7% after returning to 100 mA g(-1).

Summary: The interfacial photocatalysis of metal oxide electron transport layers (ETLs), especially TiO2, in organometal halide perovskite solar cells (PSCs) has detrimental effects on device stability. A UV absorber, 4,4'-oxybisbenzoic acid (OBBA), was used as a modification layer between TiO2 and perovskite to prevent UV photocatalytic degradation. The modified device showed a high power conversion efficiency (PCE) of up to 22.14% and excellent stability under extreme UV irradiation (365 nm, 600 mW cm(-2); 275 nm, 10 mW cm(-2)).

Summary: To improve the performance of perovskite solar cells (PSCs), researchers have used passivators to address the defects of perovskite. In this study, a passivator called TA-MN, which has a symmetric bidentate acceptor, was found to have a strong synergistic passivating ability due to the presence of two symmetric cyano groups (CN). This passivator achieved a higher power conversion efficiency (PCE) of 21.19% compared to the TA-CA passivator (20.54%) and the control group (19.49%). The TA-MN-based PSCs also demonstrated good stability and scalability. These findings provide useful insights for the design of passivators with symmetric bidentate acceptors.
