The alternative advanced lead-acid battery is one of the promising ultrabattery. The lead-carbon battery is also reusable battery consisted of positive electrodes, negative electrode and Electrolyte. Currently, numerous research efforts are performing on activated carbon used as the novel cathode materials. In this study, we have used graphite sheet coated P60 carbon as a cathode material. Graphite electrode is different form used in the normal lead-carbon batteries. It will be expected to increase the conductivity and weigh light. Through charge-discharge experiment and EIS, battery performance analysis were compared with grid form negative electrode. After that, SEM, RAMAN and XRD analyses were studied.
