As the system gets further lithiated, a significant Raman activity is observed at around 200 cm -1 [Fig. Similarly, Raman activities in the 320-400 and 420-600 cm -1 ranges arise from the lithiumsulfur structures. These activities become more noticeable with increasing number of lithium atoms. At 100% depth of discharge [Fig. (a), panel (VIII)], the dominant Raman activity in 320-400 cm -1 range coincides with the characteristic Raman activity of Li 2 S solid. The Raman activity around 450 cm -1 predominantly originates from S-S stretching vibration in longer sulfur chains. This activity is a key factor in distinguishing between long and short sulfur chains, as previously discussed. The activity at ∼450 cm -1 is found to be absent at 100% depth of discharge as there is no S-S covalent bond present in the DIB-Li 14 S 4 -DIB molecule anymore. Instead, a broad activity emerges at 100% depth of discharge at 470-550 cm -1 which seems to come almost entirely from the formed lithium-sulfur structure [see the red curve in Fig. (a), panel (VIII)]. However, our analysis based on partial Raman spectrum of the S 8 chain within DIB-S 8 -DIB shows that the activity at ∼480 cm -1 should partially arise from the DIB molecules as well. It is worth noting that this activity arising from the organic molecules should be present at all stages of discharge.
