Carbon Aerogels Are Used In Lead Batteries.​


Carbon aerogel can improve the dynamic charge accepting capacity (DCA) of lead batteries, prolong cycle life and maintain charging power. The strategically designed members rate can control the sulfation on the negatively active material during the use of a portion of the charge state and increase its charging power throughout the life of the device. Optimized surface features allow easy incorporation of discrete carbon particles into various lead paste formulations, thus ensuring a smooth transition to the next generation of carbon-reinforced lead batteries.

(1) The automobile industry

As the auto industry innovates to meet emission standards and meet on-board electronics needs, lead battery manufacturers are looking to enhance performance. By adding carbon aerogel, improved dynamic charge acceptance (DCA) performance can be maintained throughout the life of the device, resulting in greater efficiency during regenerative braking and start-stop operations. The engineered mysterious network of carbon aerogel can reduce the damage of sulfate to the electrode and prolong the cycle life under partial charge.

(2) The driving force

Deep discharge prime battery applications from scooters to forklifts are seeking more robust lead batteries. Although these applications are usually hindered by the positive electrode, the incorporation of carbon aerogel into the negative electrode has created a new way to improve the efficiency of battery systems. Carbon aerogel can achieve high charging efficiency, including regenerative braking. Shorter charging times extend operating hours and reduce idle time, thus making full use of equipment operations.

(3) Energy Storage System (ESS)

The global demand for advanced energy storage systems is driving the widespread adoption of smart grid systems and powering renewable energy sources such as wind, solar and hydropower. Carbon aerogel enhances lead battery performance beyond current ESS cycling requirements, while increasing charging power and minimizing regulation, thereby increasing grid utilization. Systems integrated with carbon aerogel have been proven in grid-scale storage and have been deployed in global wind and solar load balancing applications.
