Coal can inject some extra life into chargeable batteries for electric vehicles (EV) without burning, a new study has found.
An advanced model of a hybridized battery management system (HBMS) using coal-based pouch cell supercapacitors and Li-ion batteries in an experiment by a team of scientists helped increase the maximum speed of e-rickshaws to 45 km per hour with an additional power gain of 433 watts.
The maximum speed of e-rickshaws across the Indian market is 35 km per hour.
The study titled ‘Fabrication of pouch cell supercapacitors using abundant coal feedstock and their hybridization with Li-ion battery for e-rickshaw application’ was published in the latest issue of the Netherlands-based Journal of Energy Storage.
The authors of the study are Binoy K. Saikia, Santhi Maria Benoy, Mousumi Bora, Dipankar Neog, Dhrubajyoti Bhattacharjya, Akhil Rajbongshi, and Prasenjit Saikia. They are associated with Council of Scientific and Industrial Research (CSIR)-North East Institute of Science and Technology in eastern Assam’s Jorhat.
“For the fabrication of coal-based pouch cell supercapacitor, we synthesized highly porous, high-surface-area activated carbon with good electrochemical performances from low-grade sub-bituminous coal feedstock,” the study paper read.

Scaling Artificial Intelligence(AI) at the speed at which consultants project is not possible by the laws of physics and may not be environmentally sustainable, said Tanvir Khan, who is the Executive Vice President and Chief Operating Officer of NTT DATA North America, part of the Japanese technology services and data centre company NTT Data, in an interview with The Hindu.
