IIT Hyderabad researchers develop alternative to lithium-ion batteries

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

Chemical Sensors and Patterned Electrodes

Chemical Sensors and Patterned Electrodes Additive manufacturing (AM) is frequently used to create small-scale patterned electrodes for scientific micro-electromechanical systems (MEMS). Platypus Technologies employs this approach to generate patterned gold thin films on glass, creating these via e-beam metal evaporation using a titanium adhesion layer. This process helps improve the film’s mechanical stability. The gold films of patterned electrodes exhibit a considerable level of purity (99.999%) as well as low surface roughness that is generally down to the nanometer-scale.
