more-inFrom cell phones to e-vehicles, Li-ion batteries have become the dominant energy storage device these days. By using carbon nanotubes, a team of Indian scientists from Clemson University, USA eliminated the need for toxic organic solvents in the conventional batteries. “Traditionally, Li-ion battery electrodes are manufactured using an organic solvent called N-methylpyrrolidone or NMP for short. The team used a vertically aligned forest of carbon nanotube (sheets of atom-thick carbon rolled into a cylinder) to coat aluminium foils for achieving sponge-like capillary action. The need of the hour is batteries that have both high power and high energy.
