Behavior Modification of Nanostructured PbO₂ Electrodes in Lead Acid Batteries Changing Electrolyte Concentration and Separator

2019

Currently, lead acid battery is extensively investigated owing to its prevalent use as a starting-lighting and ignition device. An essential role for electrochemical reactions is played by the surface area available for conversion reactions and a possible approach is the use of nanostructured electrodes. In this work, lead dioxide nanostructured electrodes were tested in order to investigate the dependence of the charge and discharge behaviour on some parameters such as electrolyte concentration, and a new type of thin separator. In this last case, it is possible to reduce the size of the cell by using a very thin separator comparable to the nanostructured electrode thickness. Besides, a lo…
