April 05, 2021 Low-cost dual-carbon battery has potential in EVs, high-voltage applications The Electrochemical Energy Storage (EES) Lab at IIT Hyderabad has developed a 5V dual-carbon battery utilising self-standing carbon fibre mats as both electrodes (cathode and anode). This new model sets aside the requirement for toxic, costly, and heavy transitional metals. Energy economy based on renewable sources has been put forward as a way to shrug off the dependence on fossil fuel. Rechargeable lithium-ion batteries (LIBs) are projected to meet electric mobility, electric aviation, and stationary grid energy storage targets within the year 2030. However, LIBs need toxic and costly metals like cobalt, nickel, manganese, etc., for functioning. Geologically unsymmetrical distribution of lithium and cobalt along with geopolitics and unethical child labour centreed on mining causes havoc and fluctuations in raw material prices. It affects the market price stability of large LIB packs used in electric vehicles. In the dual-carbon battery, both the electrodes consist of carbonaceous materials, and the ions from the electrolyte intercalate and de-intercalate into the electrode matrix.
