Abstract:
Research in Li-S battery is recently becoming very popular and the potential applicability of the Li-S battery as a power source had been mentioned more than two decades ago. Its development was mainly impeded by the difficulty in the safe use of pure Li as an anode on one hand and even more critically the electrochemical use of S without encountering charge transfer problems. Furthermore, the formation of Li dendrites on the Li-anode during re-charge and the loss of available S at the cathode resulted in a rapid fade of the capacity. A summary of recent progress in Li-S battery is presented. Current development of Li-S batteries have led to > 400 Wh per Kg of energy densities, but the capacity fade with cycling is still an issue requiring scientific and technological solutions, however one can cautiously predict that the strides can prove to be more rapid than Li-ion batteries after take-off.
