Fig. 4: Correlation of phase transition by chemical and electrochemical lithiation.
From: Photoredox phase engineering of transition metal dichalcogenides
a, Chemically induced phase transition of MoS2 and WS2 observed in RICM. b, Reaction dynamics at selected points indicated in a for MoS2 and WS2 during chemical lithiation. No data were recorded for WS2 between about 220 min and 250 min. c, Electrochemical discharge/charge voltage profiles of MoS2 and WS2 versus Li/Li+. d, Energy landscape proposed for the phase transition and conversion reaction of MoS2 and WS2. The blue line shows the light-activated pathways. Arrows at the conversion barriers indicate the thermodynamic preference of the system. Scale bar, 5 μm (a).
