Abstract:
Embodiments described herein relate generally to lithium sulfur batteries and methods of producing the same. As described herein, preventing coarsening of sulfur during the well-known melt-diffusion processing of cathodes allows a high areal capacity of 10.7 mAh/cm 2  at current density of 3.4 mA/cm 2  (C-rate of 1/5 h −1 ). The addition of a lithium salt, such as LiTFSI, prior to melt-diffusion can prevent coarsening of molten sulfur and allows creation of a sulfur electrode with a high concentration of triple-phase junctions for electrochemical reaction. In some embodiments, approximately 60-70% utilization of the theoretical capacity of sulfur is reached at a high loading (e.g., greater than 7.5 mg S/cm 2 ). The electrodes are prepared in lean-electrolyte environment of 3 ml electrolyte /g sulfur  (˜70 vol % of electrolyte in the electrode) for high areal capacity in Li—S batteries.
