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.
The work is expected to result in further improvements to cycle life and specific energy of the lead-acid battery and a consequent reduction in running costs. This will in turn make the performance and COSt of an electric vehicle more attractive and hence improve their marketability.
