Dynamics of a Hybrid Aqueous-Nonaqueous Electrolyte
A new class of electrolytes has recently been reported, hybridizing aqueous with non-aqueous solvents (HANE), that inherits the non-flammability and non-toxicity characteristics from aqueous and better electrochemical stability from non-aqueous systems. In this proposal we plan to measure LiTFSI dissolved in 1-1 H2O + DMC and 1-1 D2O + d-DMC to verify the molecular diffusivities and ionic conductivities predicted by the Molecular Dynamics numerical simulations. These measurements will complement QENS measurements performed last year on the NEAT spectrometer at BENSC. With the longer (by about a factor 20) Fourier time proved ny WASP, we expect to resolve dynamics of the water molecules and the three-times heavier DMC molecules.
