IIT Hyderabad develops dual carbon alternative to lithium-ion batteries The breakthrough model, developed by a team led by Dr Surendra Kumar Martha, eliminates the requirement of toxic, costly, and heavy transitional metals. By IANS| Posted by Minhaj Adnan | Published: 5th April 2021 2:56 pm IST Hyderabad: The Electrochemical Energy Storage Lab at the Indian Institute of Technology Hyderabad (IITH), has developed a 5V Dual Carbon Battery utilising self-standing carbon fibre mats as both electrodes – cathode and anode. The breakthrough model, developed by a team led by Dr Surendra Kumar Martha, eliminates the requirement of toxic, costly, and heavy transitional metals. This more sustainable and low-cost Dual carbon battery may find potential uses in high-voltage applications, sophisticated battery-run medical devices, regenerative braking systems in electric vehicles, and stationary grids.
