INSPIRE under the Department of Science & Technology (DST), Government of India has developed porous carbon materials that have the potential to replace the lead grid in lead-acid batteries. The carbon foam was developed by Dr. Rajeev Kumar from CSIR-Advanced Materials and Processes Research Institute, Bhopal, a recipient of the INSPIRE Faculty Award.
"Through this fellowship, we have developed carbon foam with improved properties. We strongly depend on the energy storage system, such as lead-acid batteries used in automobiles and households. The lightweight carbon foam can replace the lead-acid batteries, which are heavy, corrosive, and have poor thermal stability." Dr Rajeev Kumar explained.
The lightweight carbon foam has a density of less than 0.3g/cc, high porosity of over 85%, good mechanical strength. The foam is highly resistive to corrosion, has good electrical and thermal conductivity with high surface area. It foam has potential applications in various field due to which it has attracted a lots of attention.
It can also be useful for heat sinks in power electronics, electromagnetic interference shielding in aerospace, hydrogen storage and electrode for lead-acid batteries and water purification systems.
