Abstract

The synthesis, characterization, and electrochemical properties of sulfide-based lithiumglasses are briefly reviewed. Of the many probes that have been used to study these materials two will be discussed in more detail, namely solid state NMR and conductivity measurements at high frequency (106-109 Hz). Solid state NMR is particularly useful in understanding the network structure of these glasses and the role coformers play in modifying the glass network. Electrochemical measurements, including impedance at high frequency, give information concerning dynamic processes, and show that someof these glasses are potentially useful in miniature and thin-film solid state batteries.
