The technical challenges facing lead–acid batteries are a consequence of the complex interplay of electrochemical and chemical processes that occur at multiple length scales. Atomic-scale insight into the processes that are taking place at electrodes will provide the path toward increased efficiency, lifetime, and capacity of lead–acid batteries.
Implementation of battery man-agement systems, a key component of every LIB system, could improve lead–acid battery operation, efficiency, and cycle life. Perhaps the best prospect for the unuti-lized potential of lead–acid batteries is elec-tric grid storage, for which the future market is estimated to be on the order of trillions of dollars.
In principle, lead–acid rechargeable batteries are relatively simple energy storage devices based on the lead electrodes that operate in aqueous electrolytes with sulfuric acid, while the details of the charging and discharging processes are complex and pose a number of challenges to efforts to improve their performance.
Nevertheless, forecasts of the demise of lead–acid batteries (2) have focused on the health effects of lead and the rise of LIBs (2). A large gap in technologi-cal advancements should be seen as an opportunity for scientific engagement to ex-electrodes and active components mainly for application in vehicles.
