Polysulfide Shuttle Study in the Li/S Battery System
TLDR
In this paper, the authors report a quantitative analysis of the shuttle phenomenon in Li/S rechargeable batteries and present experimental evidence that selfdischarge, charge-discharge efficiency, charge profile, and overcharge protection are all facets of the same phenomenon.Abstract:
This work reports a quantitative analysis of the shuttle phenomenon in Li/S rechargeable batteries. The work encompasses theoretical models of the charge process, charge and discharge capacity, overcharge protection, thermal effects, self-discharge, and a comparison of simulated and experimental data. The work focused on the features of polysulfide chemistry and polysulfide interaction with the Li anode, a quantitative description of these phenomena, and their application to the development of a high-energy rechargeable battery. The objective is to present experimental evidence that self-discharge, charge-discharge efficiency, charge profile, and overcharge protection are all facets of the same phenomenon.read more
