Consider:

xLi + TiS₂ Li_xTiS₂ From 0 < x 1, a Li intercalation reaction

LiTiS₂ + 3Li 2Li₂S + Ti From 1 < x 3, a conversion reaction

i) The theoretical capacity of the TiS₂ conversion reaction is stated to be around 960 mAh/g. Verify this number and explain how it was determined.

ii) 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⁺

iii) 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.
