The cycle performance tests showed that the initial cell capacity was maintained almost unchanged up to 100 cycles at 0.5 and 1 C when 2.5 wt.% of 2-butoxymethyl-1-methylimidazolium-3-propylsulfonate or 2-butoxymethyl-1-butylimidazolium-3-propyisulfonate was added to the model electrolyte (1 M LiPF6 in ethylene carbonate, dimethyl carbonate and ethylmethyl carbonate (1/1/1 v/v/v)). Structures of zwitterionic compounds and their interactions with lithium ions were theoretically investigated. (c) 2008 Elsevier B.V. All rights reserved.
