Recent advancements in lead-acid batteries are focused on higher performance as well as on lowering the overall environmental footprint of the battery lifecycle. Ahlstrom’s portfolio for battery materials includes a wide range of pasting materials, film separator reinforcement, and Absorbent Glass Matt (AGM) media.
Importance of carbon additives to the positive electrode in lead-acid batteries. Mechanism underlying the addition of carbon and its impact is studied. Beneficial effects of carbon materials for the transformation of traditional LABs. Designing lead carbon batteries could be new era in energy storage applications.
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).
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.
Although lead acid batteries are an ancient energy storage technology, they will remain essential for the global rechargeable batteries markets, possessing advantages in cost-effectiveness and recycling ability.
The growth of lead sulfate crystals on the surface of the electrode is supported by the high discharge rates of the battery [34, 35].
