Abstract:
The physicochemical properties of glyme-Li[FSA] (FSA: bis(fluorosulfonyl)amide) equimolar complexes were investigated. The self-diffusion coefficients of glymes and Li + as determined by pulsed-field gradient spin-echo nuclear magnetic resonance spectroscopy in equimolar complexes were almost identical, suggesting that all of the glyme molecules coordinated with Li + . Electrochemical characterization revealed that the oxidative stability of glyme molecules was enhanced by complexing with Li + . Using [Li(glyme) 1 ][FSA] electrolytes and a LiFePO 4 cathode, a lithium secondary battery could be stably operated for more than 100 cycles at room temperature.
