Li-Reactivity of Silicate Glasses: Influence of Glass Composition

摘要

This investigation has concentrated on the reactivity of alumino-silicate glasses with lithium, in consideration of applications for separator papers in Li/SOC12 cells. Although the silicate matrix is unstable with respect to lithium, additives to the glass can decrease or increase the overall glass reactivity. We have shown that, even in the presence of a stabilizing aluminium addition, sodium oxide exchange and reduction occurs immediately, causing increased tendency to react as compared to pure silica. Addition of calcium rather than sodium to the glass, however, allows for a material with increased stability as compared to silica. 9 refs., 6 figs., 2 tabs. (ERA citation 14:006070)
