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.
In all cases the positive electrode is the same as in a conventional lead–acid battery. Lead–acid batteries may be flooded or sealed valve-regulated (VRLA) types and the grids may be in the form of flat pasted plates or tubular plates. The various constructions have different technical performance and can be adapted to particular duty cycles.
Deyab, M. A. Ionic liquid as an electrolyte additive for high performance lead-acid Batteries. J. Power Sources390, 176–180 (2018). Ghavami, R. K., Kameli, F., Shirojan, A. & Azizi, A. Effects of surfactants on sulfation of negative active material in lead acid battery under PSOC condition. J. Energy Storage7, 121–130 (2016).
One major cause of failure is hard sulfation, where the formation of large PbSO 4 crystals on the negative active material impedes electron transfer. Here, we introduce a protocol to remove hard sulfate deposits on the negative electrode while maintaining their electrochemical viability for subsequent electrodeposition into active Pb.
The lead–acid battery has undergone many developments since its invention, but these have involved modifications to the materials or design, rather than to the underlying chemistry. In all cases, lead dioxide (PbO 2) serves as the positive active-material, lead (Pb) as the negative active-material, and sulfuric acid (H 2 SO 4) as the electrolyte.
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.

The chemical reactions are again involved during the discharge of a lead–acid battery. When the loads are bound across the electrodes, the sulfuric acid splits again into two parts, such as positive 2H + ions and negative SO 4 ions. With the PbO 2 anode, the hydrogen ions react and form PbO and H 2 O water. The PbO begins to react with H 2 SO 4 and …
