We introduced a methodology for clearing Pb negative electrodes from hard sulfate deposits via a chelation procedure, and further using the resulting chelate-metal solutions for an electrodeposition step to refurbish the electrode.
To evaluate electrodeposition of Pb films from Pb-EDTA, we used Au disk electrodes (radius = 1 mm) and unused negative electrodes from the Yuasa battery. Potentiostatic and galvanostatic methods were applied to deposit films under ambient conditions. We analyzed the films with microscopy, optical profilometry, and SEM.
Electrochemical Society Member. Lead acid batteries (LABs) remain an inexpensive energy storage technology with a wide application base. However, their short cycle lifetimes necessitate improved recycling and maintenance technologies to combat their various failure modes.
Lead-acid batteries (LABs) have been a kind of indispensable and mass-produced secondary chemical power source because of their mature production process, cost-effectiveness, high safety, and recyclability [ 1, 2, 3 ].
To put the chelated material back in service at the negative electrode, we explored a two-step process involving: (1) sulfate removal to reactivate the electrode surface, then (2) using the reactivated electrode to reduce Pb-EDTA directly and redeposit fresh, active electrode material. Figure 2.
Nevertheless, to the best of our knowledge, little research has been reported using PVA as the negative additive of LABs. It has been proven that the presence of sulfonate plays a role in inhibiting the sulfation of negative electrodes during the discharge process [ 15, 16 ].
