Summary

Descripción general del contenido del recurso.

In this paper, cells with added HCl in the electrolytes were prepared respectively. The result of HCl added sample shows a higher open circuit voltage (OCV) than a commercial one and even higher than that of a theoretical one. Its current density also shows 0.02 A/cm2 higher than that of commercial one. It will be an advantage in redox reaction through removal of reaction product and decreasing of pH by HCl. From the XRD result of anode Zn plate, ZnCl24Zn(OH)2H2O was mainly found on the plate. On the other hand, the HCl added sample shows only one species of ZnO and Zn(OH)2. This result can explain that ZnCl24Zn(OH)2H2O is easily disrobed in HCl solution. These results suggest that another reaction occurred at the same time with the normal redox reaction by HCl addition. In addition, standard electrode potential will change with pH of electrolyte. It is easy to realize from Nernst equation and a decrease of pH will raise OCV and current density. In this paper, the possibility of high performance manganese dry battery is shown.
