Abstract
Several new acyclic ammonium-TFSI ionic liquids with an allyl substituent(s)
were synthesized and their physicochemical and electrochemical properties were
characterized. [AAMM]Am-TFSI (3) with two allyl groups showed the widest
electrochemical stability window (5.9 V) among the ammonium-based ILs reported to date
because of the increment of both the anodic and cathodic limits. The charge-discharge
performance of a LiCoO2-based half-cell containing [AAMM]Am-TFSI as an electrolyte
was better in cycleability (the capacity retention ratio: 99% after 20 cycles) than that of the
cell with the corresponding partially saturated analogue, [AMMP]Am-TFSI (2) (the
capacity retention ratio: 92% after 20 cycles).
