The lead–acid battery is a type of rechargeable battery first invented in 1859 by French physicist Gaston Planté. It is the first type of rechargeable battery ever created. Compared to modern rechargeable batteries, lead–acid batteries have relatively low energy density. Despite this, they are able to supply high surge currents.
Notable exceptions include the models developed by Shah et al. 24 and by Li and Hikihara 25 for the all-vanadium system and by Scamman et al. 3 for the bromide–polysulphide battery. There are no models, as far as the authors are aware, of the soluble lead-acid flow battery, even in the simplest cases.
Lead–acid batteries were used to supply the filament (heater) voltage, with 2 V common in early vacuum tube (valve) radio receivers. Portable batteries for miners' cap headlamps typically have two or three cells. Lead–acid batteries designed for starting automotive engines are not designed for deep discharge.
Lead-acid flow batteries are a promising technology for grid-scale energy storage. Flow batteries can be easily scaled to fit any system requirements making them optimal for load leveling. When energy storage must be increased, all that needs to be changed is the capacity of the electrolyte storage tanks.
