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

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

1. Weve already seen how the energy density of the cell is dependent on its capacity and cell voltage. 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⁺, corresponding to the data shown in Figure 1a of Zhangs article). State your assumptions and show all of your work.
2. 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. Use the data for cycle 1 of Figure 1c of Zhangs article to estimate the energy of the cell using the conversion mechanism. State your assumptions and show all of your work.
3. What do you see as some advantages and disadvantages of the intercalation vs. conversion mechanisms using TiS₂ as an electrode?
