a) Li plating/stripping behaviour in electrolyte containing 50 mM TAC, the inset is a Li disk stored in the same electrolyte after six months; b) cyclic voltammograms at various scan rates; c) plots of peak current vs square root of the scan rate and linear fits; d) cyclic voltammograms scanned at 100 mV s⁻¹; e) photographs of the as-synthesized TAC cation salt and dication salt, photographs of holding a electrochemical device contained TAC cation electrolyte at a constant-potential of 4.1 V (vs. Li⁺/Li); f) UV-vis spectra of TAC cation and dication solutions.
