Outline of Final Research Achievements |
In this research project, we constructed an electrochemical measurement system that performs charge and discharge reactions under electrochemical reaction systems of lead (Pb) for the negative electrode and lead dioxide (PbO2) for the positive electrode under temperature controlled conditions in a thermostatic chamber. Experimental analysis method for evaluating thermodynamic properties, i.e. ΔG, ΔH, ΔS was established by measuring the electrode internal temperature in consideration of material physical properties. As a result, it was revealed that | ΔG |> | ΔH | in the discharge reaction of the electrochemical reaction system constructed from the practically used lead storage battery electrode, that is, it is possible to improve the energy quality for exergy regeneration.
