Fig. 4: Performance of PS-LMTO vs. NM-LMTO in the 70(LMTO):20(MWCNT):10(PVDF) electrode in Li||PS/NM-LMTO cells.

a, b Voltage profiles of (a) PS-LMTO and (b) NM-LMTO when cycled between 1.5 and 4.8 V at 20 mA/g and 25 °C, and (c) their capacity retention and coulombic efficiency (%). d, e The dQ/dV plots over various cycles of (d) PS-LMTO and (e) NM-LMTO from the above tests, with legends indicating the corresponding cycle numbers, and (f) their average discharge voltage retention. g, h The discharge voltage profiles of (g) PS-LMTO and h NM-LMTO when they are charged at 20 mA/g to 4.8 V and discharged at different rates of 10, 20, 100, 200, 400, 600, 800, and 1000 mA/g to 1.5 V at 25 °C. The NM-LMTO in this figure was prepared with an initial molten-salt calcination at 800 °C for 5 min followed by the annealing at 600 °C for 20 h with a precursor-to-salt weight ratio of 1:1.5. Source data for (a–h) are provided as a Source Data file.
