Scientists at the Institute of Nano Science and Technology (INST), Mohali, an autonomous institute under the Department of Science and Technology, Government of India, have developed a stable material for pseudocapacitors or supercapacitors which store electrical energy by electron charge transfer. The material can offer a low-cost scalable energy storage solution as an alternative to batteries.

Dr. Ramendra Sundar Dey and his team from INST have formulated an interesting synthetic strategy to overcome the long-standing challenges of pseudocapacitors, their cycling stability, and rate capability. Pseudocapacitors are a type of supercapacitors which store electrical energy by electron charge transfer.

The team has developed the pseudocapacitive material, a hybrid xerogel structure (a solid formed from a gel by drying with unhindered shrinkage), for the very first time. The hybrid material was fabricated by the integration of a well-known organic molecule, dopamine onto a conductive matrix, like graphene.

This class of xerogel architectures, although reported in the literature as alternatives to conventional pseudocapacitors, lack sufficient cycling stability to replace batteries in the consumer market.
