Without judicious practice, both the benefits of adding carbon and the stumbling block of hydrogen evolution are expected to carry over into lead–acid batteries in stationary energy storage. One or more of the following mechanisms may serve to provide the improvement that, in some cases, carbon brings.
In the last 20 years, lead-acid battery has experienced a paradigm transition to lead-carbon batteries due to the huge demand for renewable energy storage and start-stop hybrid electric vehicles.
Electrochemical Energy Reviews - The lead acid battery has been a dominant device in large-scale energy storage systems since its invention in 1859. It has been the most successful commercialized Since PbSO 4 has a much lower density than Pb and PbO 2, at 6.29, 11.34, and 9.38 g cm −3, respectively, the electrode plates of an LAB inevitably

Even though lead–acid batteries (LABs) are the oldest electrochemical energy storage technology, they still attract some interest due to their low price and easy recyclability [1,2,3]. On the other hand, they are outperformed by Li-ion batteries (LIBs) when it comes to weight, since their specific energy is limited to 30–40 Whkg −1 [ 4, 5 ], while
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.
