Summary: Single-phase three-dimensional vanadium oxide (V4O9) was synthesized by reduction of V2O5 using a gas stream of ammonia/argon (NH3/Ar). The as-synthesized oxide was transformed into a disordered rock salt type-Li3.7V4O9 phase while cycling over the voltage window 3.5 to 1.8V vs. Li. The Li-deficient phase delivers superior reversibility and capacity utilization compared to battery grade V2O5 cathodes in lithium cells.

Summary: In this paper, different methods were employed to prepare lithium vanadium oxide (LVO) samples. It was found that the LVO samples obtained by sol-gel method had uniform nanoparticle morphology. The LVO/graphene (GN) composite synthesized by sol-gel method showed outstanding cycling performance and rate performance, attributed to the improved distribution of LVO by flexible GN and the formation of a highly conductive network.

Summary: The nanostructured Sn(SnO2)/TiO2(B) ultrafast-charging materials exhibit excellent cycling stability and high storage capability, functioning effectively at high current densities with a low transfer resistance and high lithium-ion diffusion coefficient. Additionally, the composite architecture of the electrode allows for fast lithium-ion diffusion and storage, while the stable SEI layer prevents the pulverization and separation of nanoparticles, indicating promising potential as anode materials in future battery applications.

Summary: Solar power is an abundant and readily available source of renewable energy, but its intermittent nature requires external energy storage solutions that are often expensive and inefficient. This study introduces the concept of a photo-accelerated battery that integrates energy harvesting and storage functions in a single device. By using a novel approach to craft photocathodes, the research demonstrates improved performance in terms of capacity and diffusion kinetics when exposed to light. This defect engineering strategy shows promise for future high-performance photocathodes in energy storage applications.
