Rechargeable lithium/iodine battery with superior high-rate capability by using iodine–carbon composite as cathode

Abstract

A rechargeable lithium/iodine battery using commercial organic electrolyte, composed of iodine–conductive carbon black composite as cathode and metallic lithium as anode, is first proposed in this work. The fabricated lithium/iodine battery presents superior high-rate capability and good reversibility based on the contributions from both the capacitive characteristics of conductive carbon black, and the redox capacity of active iodine in the composite.
