Article Synopsis
- The demand for better energy storage solutions is driving research into efficient electrode materials for rechargeable batteries that offer higher energy density and longer lifespan.
- Utilizing aerosol spray techniques like spray pyrolysis and spray drying provides a reliable and cost-effective way to create desired nanostructured materials for electrodes, allowing control over their properties.
- The article reviews recent advancements in these spray methods, focusing on how they can enhance various types of batteries (like lithium-ion and lithium-sulfur), while also discussing the mechanisms involved in creating these nanostructured materials.
Multicomponent materials with various double cations have been studied as anode materials of lithium-ion batteries (LIBs). Heterostructures formed by coupling different-bandgap nanocrystals enhance the surface reaction kinetics and facilitate charge transport because of the internal electric field at the heterointerface. Accordingly, metal selenites can be considered efficient anode materials of LIBs because they transform into metal selenide and oxide nanocrystals in the first cycle.

A NiMoO4 yolk-shell architecture formed via spray pyrolysis is transformed into equally structured NiSe2-MoSe2 composite microspheres. Because of the complementary effect between the Ni and Mo components that prevents severe crystal growth during selenization, NiSe2-MoSe2 nanocrystals are uniformly distributed over the yolk-shell structure.
