Question: Consider: xLi + TiS2 LixTiS2 From 0 < x 1, a Li intercalation reaction LiTiS2 + 3Li 2Li2S + Ti From 1 < x 3,
Consider: xLi + TiS2 LixTiS2 From 0 < x 1, a Li intercalation reaction LiTiS2 + 3Li 2Li2S + Ti From 1 < x 3, a conversion reaction
a) Determine the energy of the Li/TiS2 cell utilizing the intercalation mechanism (from the voltage range of between 3.0 and 1.4 V vs. Li/Li+
b) Now, consider the Li/LiTiS2 cell utilizing the conversion mechanism, which has a lower cell voltage (from 0.5 to 0.05 V vs. Li/Li+ ) but can deliver a higher capacity. Estimate the energy of the cell using the conversion mechanism.
