“…[9][10][11][12] For example, at 30 1C, the viscosity and ionic conductivity of the neat IL (without any lithium salt) 1-methoxymethyl-1,1,1-trimethylammonium TFSI [N 111,1O1 ] [TFSI] is 44 mPa s and 4.8 mS cm À1 , compared to 63 mPa s and 3.5 mS cm À1 for the alkyl equivalent 1-propyl-1,1,1-trimethylammonium TFSI [N 1113 ][TFSI]. 13,14 In another study, the viscosity and ionic conductivity of (N-(2-methoxyethoxy)methyl)-N-methylpiperidinium TFSI [C (1O2O1) mpip][TFSI] at 30 1C is 69 mPa s and 2.3 mS cm À1 respectively, compared to 132 mPa s and 0.8 mS cm À1 for N-hexyl-N-methylpiperidinium TFSI [C 6 mpip][TFSI]. 15 For lithium batteries, IL electrolytes are prepared by dissolving the corresponding lithium salt (e.g.…”
