Packing batteries with more punch
Indian researchers are working on cells that can store more energy, last longer
The scientific world is all charged up about developing batteries that can store more energy — and India seems to be at the forefront of the exercise.
A cell, which is a unit of a battery, has four parts — anode, which supplies electrons; cathode, which receives them; electrolyte, the medium through which the anode atoms that have lost an electron (or ion) move to the cathode; and separator, a physical barrier between anode and cathode (together called electrodes).
Of these, the separator’s role is limited; intense research is on globally to make the other three better.
