Lead acid batteries are the energy storage workhorse and the most ubiquitous form of energy storage in the world. Applications range from automotive starter batteries to batteries for data-center backup power and renewable energy integration. The lead acid chemistry is extremely robust and well-understood and lead acid batteries function well in a broad range of temperatures and environmental conditions.
New Challenges for Lead Acid
For many years, the lead acid chemistry has been sufficient for most of the applications that it served. However, new technologies have brought the performance limitations of the lead chemistry into clear focus. In the automotive sector, the start-stop hybrid requires the battery to provide many more cycles at a higher rate of charge and discharge than a traditional lead acid battery can accomplish. Utility-scale renewable storage applications demand a lower cost-per-unit of energy stored over the life of the battery (kWh cycles) than a traditional lead acid battery can achieve. These and other applications have forced the manufacturers of lead acid batteries to seek new solutions for new problems and to fundamentally re-engineer these batteries.
Performance from Materials
Innovative materials are opening new performance horizons for lead acid batteries. The most important of these materials are carbon additives for the lead electrodes and the absorbed glass mat separators used in valve regulated lead acid batteries. Carbon added to the negative plate of a lead acid battery dramatically increases the power, charge acceptance and cycle life of the battery. However, in order to be effective, the carbon must have a precisely tailored pore structure, and it must be extremely pure.
The EnerG2 Advantage
EnerG2 carbon offers the precisely tailored pore structures and high purity required to enhance the performance of lead acid batteries. Our materials provide the power, charge acceptance and cycle life improvements that enable lead acid batteries to meet the demands of new high performance applications like start-stop hybrids.
