Cycling of Li/Li3N/TiS2 solid state cells

Abstract Solid state cells with the configurationLi/Li3N/LiCF3SO3-(PEO)9/TiS2 have been constructed and cycled in the temperature range 120–170°C. Current densities of 0.25–2.0 mA/cm2 were employed. Thin (30–50 micron) cathodes of pressed TiS2 powder were used in order to obtain reasonably large capacity utilizations (∼80%) at stoichiometric discharge times of the order of a few hours. Up to 205 cycles have been obtained. The results indicate the feasibility of a moderate temperature solid state system.
