Optimising the concentration of LiNO3 additive in C4mpyr-TFSI electrolyte-based Li-S battery
Abstract
In the lithium-sulfur (Li-S) context, LiNO3 is known to improve the battery performance by protecting the lithium anode and suppressing the associated lithium polysulfides shuttle effect during cycling. Herein, the variation of the LiNO3 additive concentration (0.05 to 0.4 mol kg-1) in a C4mpyr-TFSI electrolyte-based Li-S system along with their transport properties are investigated, in which an electrolyte with 0.1 mol kg-1 LiNO3 additive showed the best performance in agreement with the data obtained for their transport properties in which this electrolyte has higher conductivity and shows the lowest glass transition temperature (Tg) measured with differential scanning calorimetry (DSC). Furthermore for this electrolyte, higher species mobility were obtained from diffusion coefficient measurements using multi-nuclear Pulsed field gradient-NMR (PFG-NMR). The lower diffusion coefficient values for TFSI- and Li+ (in spite of its small size) compared with the pyrrolidinium cation, confirming that the transport of these ions is in the form of complexes such as [Li(TFSI)n](n-1)- in the electrolyte.
