Extended Data Fig. 2: Li-Fe-F phase diagram.
From: Revisiting metal fluorides as lithium-ion battery cathodes
The reference phases in the phase diagram are labelled and indicated by light blue circles so as to show the positions of A- and B-LixFeyF3, whose Fe concentration is off-stoichiometric. The reaction pathways associated with the FeF3 and FeF2 systems are respectively marked by using green and pink dashed arrows. Each reaction process is also labelled with its respective roman numeral used to label the equations in the manuscript.
