Lead-acid battery is the oldest example of rechargeable batteries dating back to the invention by Gaston Planté in 1859 [8]. In the cell configuration, the lead electrodes were separated by a glass-microfiber separator. Two GDEs were respectively placed next to Pb and PbO 2 electrodes with a sandwiched separator. Ti-plates were employed as the current
