Carbon additives in negative active material (NAM) electrodes enhances the cycle life of the Lead Acid (LA) batteries. Hydrogen evolution reactioncaused by carbon additives can be controlled with lead-carbon composites or metal/metal-oxides.
The lead–carbon electrode is a negative anode with a small number of carbon additives. The LAB which was developed with a lead–carbon negative electrode defined as an LCB. When nanosized CB is used as an additive, lead–carbon electrodes exhibit different electrochemical behaviors.
It has a high electrical conductivity, large specific surface area, low cost, and environmental impact . The idea of the lead-acid battery with carbon capacitor electrode is applied in hybrid supercapacitors. They employ negative plates as capacitors, where lead in the active mass is replaced by carbon materials.
In the last 160 years, many applications have been found and they are still in a widespread use, e.g., as car batteries or a backup power. The lead-acid battery is a secondary cell, where during a discharge, it produces lead (II) sulfate (IV) from a metallic lead (on the negative electrode) and from lead (IV) oxide (on the positive electrode).
Carbon can also be used in the battery construction as a capacitor electrode allowing them to achieve a higher power density. Spread of mentioned carbon-based improvements in the lead-acid battery construction can lead to many further years of the economically feasible use of this type of batteries.
Designing lead carbon batteries could be new era in energy storage applications. Although, lead-acid battery (LAB) is the most commonly used power source in several applications, but an improved lead-carbon battery (LCB) could be believed to facilitate innovations in fields requiring excellent electrochemical energy storage.
