“…[ 41 ] The electrodeposition of Pb from first‐generation chloridoaluminate ILs has been extensively studied, and in these systems, lead chloride (PbCl 2 ) was used, which is a synthetic compound. [ 42,43 ] Using second‐generation ILs, Pb has been successfully electrodeposited from wet [EMIm][NTf 2 ] ([EMIm] + = 1‐ethyl‐3‐methylimidazolium), [ 44,45 ] [BMPyrr][NTf 2 ] ([BMPyrr] + = 1‐butyl‐1‐methylpyrrolidinium), [ 46 ] and the distillable IL dimethylammonium‐dimethylcarbamat (DIMCARB), [ 47 ] respectively. However, lead dioxide (PbO 2 ) and lead sulfate (PbSO 4 ), which are main components of the lead‐acid battery, are insoluble in the mentioned ILs.…”

Ionometallurgy is a new development aiming at the sustainable low‐temperature conversion of naturally occurring metal ores and minerals to their metals or valuable chemicals in ionic liquids (ILs) or deep eutectic solvents. The IL betainium bis((trifluoromethyl)sulfonyl)imide, [Hbet][NTf2], is especially suited for this process due to its redox‐stability and specific‐functionalization. The potentiostatic electrodeposition of zinc and lead starting directly from ZnO and PbO, which dissolve in [Hbet][NTf2] in high concentrations is reported. The initial reduction potentials of zinc(II) and lead(II) are about −1.5 and −1.0 V, respectively. The ionic conductivity of the solution of ZnO in [Hbet][NTf2] is measured and the effect of various temperatures and potentials on the morphology of the deposited material is explored. The IL proves to be stable under the chosen conditions. From IL‐solutions, where ZnO, PbO, and MgO have been dissolved, metallic Zn and Pb are deposited under potentiostatic control either consecutively by step‐electrodeposition or together in a co‐electrodeposition. Using the method, Zn is also deposited on 3D copper foam and assembles into high‐voltage zinc‐graphite battery. It exhibits a working‐voltage up to 2.7 V, an output midpoint discharge‐voltage of up to 2.16 V, up to 98.6% capacity‐retention after 150 cycles, and good rate performance.

The lead-acid battery recycling industry is very well established, but the conventional pyrometallurgical processes are far from environmentally benign. Hence, recent developments of lead-acid battery recycling technologies have focused on low-temperature (electro-)hydrometallurgical processes, the subject of this review, covering modified electrolytes, improved reaction engineering, better reactor design and control of operating conditions.

“…At present, two main types of ILs are used for electrodeposition: first‐generation chloridoaluminate ILs, and second‐generation “air‐ and water‐stable” ILs with anions such as tetrafluoroborate, (BF 4 − ), hexafluorophosphate (PF 6 − ), trifluoromethanesulfonate ([OTf] − , CF 3 SO 3 − ) or bis(trifluoromethylsulfonyl)imide ([TFSI] − , [NTf 2 ] − , (CF 3 SO 2 ) 2 N − ) [1,3,9] . A large number of studies have been reported on the electrodeposition of single metals or alloys based on chloridoaluminate ILs [15–18] . The biggest drawback of first‐generation ILs is that they are extremely susceptible to hydrolysis and require inert conditions for electrodeposition [3] .…”

Zinc electrodeposition is currently a hot topic because of its widespread use in rechargeable zinc-air batteries. However, Zn deposition has received little attention in organic solvents with much higher ionic conductivity and current efficiency. In this study, a Zn-betaine complex is synthesized by using ZnO and betainium bis[(trifluoromethyl)sulfonyl]imide and its electrochemical behavior for six organic solvents and electrodeposited morphology are studied. Acetonitrile allowed dendrite-free Zn electrodeposition at room temperature with current efficiencies of up to 86 %. From acetonitrile solutions in which Zn, Pb, and Cu complexes are dissolved in high concentrations, Zn and Pb/ Cu are efficiently separated electrolytically under potentiostatic control, allowing the purification of solutions prepared directly from natural ores. Additionally, a highly flexible Zn anode with excellent kinetics is obtained by using a carbon fabric substrate. A rechargeable zinc-air battery with these electrodes shows an open-circuit voltage of 1.63 V, is stable for at least 75 cycles at 0.5 mA cm À 2 or 33 cycles at 20 mA cm À 2 , and allows intermediate cycling at 100 mA cm À 2 .
