Optimum calcination temperature for the synthesis of nanostructured alumina for energy storage heat management applications

Heat management for rechargeable energy systems such as lithium-ion batteries are of great performance and safety value. Optimization of solid additives to liquid cooling systems are a field of research for the advanced materials selection and characterization. While alumina showed proper traits to be used as additive in the LIB liquid cooling systems, nano-structuring of the particles entails promises for further improvement of the structural and heat dissipating capabilities of the ceramic oxide. Here a neat and efficient synthesis route is reported to obtain nanostructured alumina with a crystallite size around ۱۰۰ nm. The effect of calcination temperature, ranging from ۴۰۰ C to ۸۰۰ C was studied on the microstructure of the synthesized Al۲O۳ nanopowder. It was established that the calcination temperature of ۶۰۰ C may be considered as the optimum temperature for obtaining a porous nano-sized alumina with uniformly distributed particle size. This can be a proper candidate for heat management systems using a liquid combination such as water/Al۲O۳ for energy storage systems e.g. LIBs.
