Summary: A porous coating structure transition metal oxide ZnCo2O4@NiMoO4 composite was successfully synthesized on the surface of carbon paper (CP) by a simple two-step hydrothermal method as a Pt-free material. The composite material showed remarkable electrocatalytic performance in reducing iodine electrolytes and improving the photoelectric conversion efficiency (PCE) of dye-sensitized solar cells (DSSCs). Equipped with ZnCo2O4@NiMoO4/CP material, the DSSCs achieved a PCE of 9.30%, higher than that of Pt counter electrodes (CEs) under the same light conditions. The titanium mesh substrate also contributed to the improved performance by increasing contact area and enhancing electron transmission.

Summary: Porous nanopetals of MnMoO4 with oxygen vacancies exhibit higher specific surface area and more diverse pore size distribution compared to MnMoO4 nanopetals. The introduction of oxygen vacancies leads to decreased energy band gap, increased electron state distribution at Fermi energy level, enhanced specific capacitance, and improved capacitance retention rate for MnMoO4-OV. These results demonstrate the beneficial effects of oxygen vacancies on the supercapacitive performance of MnMoO4-OV.

Summary: Metal molybdates, inheriting the characteristics of polyoxometalates, have been widely used in various fields. However, the construction of hierarchical molybdate nanostructures with superior performance remains a challenge. In this study, hierarchical manganese molybdate nanocauliflowers were synthesized from aggregated microrods using dopamine as a scissor, and a carbon coating layer was introduced through a simple calcination. The MnMoO4/C nanocauliflowers exhibited excellent electrochemical properties as anodes for lithium/sodium ion batteries, surpassing the performance of bare MnMoO4. The stable cyclic property without obvious capacity fading was also superior to previous reports. This study demonstrates a simple yet effective strategy for structure engineering and surface modification of molybdates.

Summary: This paper discusses the safety issues of lithium-ion batteries (LIBs) and sodium-ion batteries (SIBs). LIBs face the danger of thermal runaway, while SIBs have advantages in safety and raw material cost, but are challenged by low energy density and poor sodium kinetics. In addition, the higher solubility of the solid electrolyte interface (SEI) in SIBs may lead to undesired side reactions. The paper reviews various experimental and modeling methods for thermal runaway detection and discusses future directions for the development of a battery management system (BMS) that can identify precursors to thermal runaway and implement mitigation strategies.
