Historically, in 1977, Frits Beck first patented the development of rechargeable soluble lead redox flow battery and called it "lead perchlorate cells" since Pb and PbO 2 are deposited from an aqueous electrolyte containing lead perchlorate dissolved in perchloric acid. 80 Also, similar flow cells were reported using lead tetra-fluoroborate in tetrafluoroboric acid.
