The use of S, S dialkyl dithiocarbonates in Li-ion battery electrolytes

S,S dialkyl dithiocarbonates such as S,S dimethyl dithiocarbonate and S,S diethyl dithiocarbonate were tested as solvents for rechargeable Lithium-ion batteries. Graphite electrodes can be successfully cycled at high reversible capacities in an S,S dimethyl dithiocarbonate solution containing 1M LiAsF 6 , while lithium ions cannot intercalate into graphite in S,S diethyl dithiocarbonate solutions Fourier Transform Infrared Spectroscopy, cyclic voltammetry and chronopotentiometric methods were used in order to monitor the reaction mechanism.
