The present study was conducted a two-step synthesis assisted by an ultrasound technique to prepare Al2O3 nanofluids for the thermal-electrochemistry experiment [1,2]. In addition, a sedimentation experiment verified suspensibility, stability, and thermal conductivity to determine the best mixing method. 0.5-2.5 wt.% single nanofluids were added into a battery cell with copper and Aluminium electrodes for an oxidation reduction reaction to test the generating capacity between 20 and 40 ˚C. The derived two empirical formulas of thermal conductivity and generating capacity for alumina nanofluids using the innovation dimensional analysis to examine the functional relationships between experimental parameters. The results of the property verification and experimentation indicated that Al2O3 nanofluid and emulsifying agent mixture at a concentration of 1wt.% had the best thermal conductivity, and that this decreases as the concentration increases. At 40 ˚C, 2.5 wt.% nanofluid also had the highest electric charge density; however, the rate of increase was less than 7% higher than that for 2 wt.% nanofluid. The 0.5-2.5wt.% Al2O3 nanofluid between 20 and 40 °C, inserting the temperature and concentration parameters can estimate the thermal conductivity and the electric charge density using the empirical formulas in the present study.
