Electrochemical response of HC half-cells, with and without enflurane, in 1 M NaPF₆ PC. (a) Comparison of the cycling performance. Charge–discharge profiles and Coulombic efficiency trends for (b) additive-free (c) enflurane containing cells. The data were obtained by applying a formation step of two cycles at 20 mA g^–1, followed by cycling at 50 mA g^–1 between 2 and 0 V versus Na⁺/Na.
