Performance of thermochemical energy storage for spinel CuMn2O4 material

Because of spinel's suitable redox properties, this article focuses on its application as a candidate of thermochemical energy storage materials. Pechini method was used to synthesize of the copper and manganese mixed metal oxides with spinel structure. X-ray diffraction (XRD) was used to determine the crystal structure of the sample. The thermochemical energy storage of the samples was measured by thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC). It was found that sample with Cu mole ratio 1/3 showed suitable cycle stability and more flexible temperature range. It is a potential candidate for thermal energy storage material. Through the comparison of air and nitrogen-air redox cycle, it is revealed that the reduction is more thorough in inert atmosphere than in air atmosphere.

Automated summary

This article investigates the potential of spinel as a candidate for thermochemical energy storage materials, demonstrating its suitable redox properties and cycle stability. Samples with a Cu mole ratio of 1/3 exhibit the best performance in terms of cycle stability and flexibility in temperature range, indicating its potential as a thermal energy storage material. Additionally, comparing air and nitrogen-air redox cycles reveals more thorough reduction in an inert atmosphere.
