Past, present, and future of lead–acid batteries
W hen Gaston Planté invented the lead–acid battery more than 160 years ago, he could not have fore-seen it spurring a multibillion-dol-lar industry. Despite an apparently low energy density—30 to 40% of the theoretical limit versus 90% for lithium-ion batteries (LIBs)—lead–acid batteries are made from abundant low-cost materials and
Solved 3.7 The evolution of oxygen is an important process
3.7 The evolution of oxygen is an important process in the lead- acid battery. Assuming that the positive electrode of the flooded lead-acid battery is at its standard potential (entry 2 in Appendix A), calculate the overpotential for the oxygen evolution reaction. It is reported that the Tafel slope for this reaction is 120 mV per decade at 15 ...
Oxygen evolution on alpha-lead dioxide electrodes in methanesulfonic acid
This work examines the oxygen evolution reaction (OER) taking place on α-PbO 2 electrode in methanesulfonic acid (MSA) medium and in sulphuric acid as a comparison, by means of cyclic voltammetry (CVA) and electrochemical impedance spectroscopy (EIS), for soluble lead acid flow battery applications. The influence of MSA …
Valve-regulated lead-acid batteries
This internal oxygen-cycle is the same principle that characterizes the sealed nickel/cadmium battery. In lead-acid batteries, however, it can only be approximated, since a certain hydrogen evolution at the negative electrode and grid corrosion at the positive electrode are always present as secondary reactions (cf. Fig. 1).
The Basic Chemistry of Gas Recombination in Lead-Acid Batteries …
Oxygen-recombination chemistry has been wedded to traditional lead-acid battery technology to produce so-called sealed, or valve-regulated, lead-acid products. Early attempts to incorporate recombination into lead-acid batteries were unsuccessful because of excessive cost, size, and/or complexity, and none were effectively commercialized.
