Beyond Li-Ion Batteries: Future Prospects for Li-S Batteries

Topic: 14
Abstract:
Li-S batteries are likely to have a promising role to play in the next generation of energy storage technology. The interest arises from several favorable factors: high specific capacity of sulfur at 1670 mAh g-1; abundance in nature and from desulfurised waste dumps; low-cost; and non-toxicity. The practical applications are still hampered by several issues: extremely low conductivity of S and the final discharge product Li2S; shuttling of soluble intermediate polysulfides between electrodes; poor utilization of S; low coulombic efficiency; large volume change of S upon lithiation; and low cycle life from fast capacity fade.
Strategies that promise to offer solutions to deal with the above technical barriers are presented.
