Extended Data Fig. 4: Nanorod structure after 15 cycles.
From: Understanding the conversion mechanism and performance of monodisperse FeF2 nanocrystal cathodes
a,b, Bright field TEM images comparing single nanorods after 15 cycles in the IL and LP30 electrolytes. c,d, The corresponding FFTs colored to differentiate between multiple phases present. Greater shape preservation is observed in the IL electrolyte. Strong rocksalt reflections in (c) indicate largely incomplete reconversion. Scale bars, 20 nm.
