Fig. 4

Particle size of a LiFeHCF-5, b LiFeHCF-3, c LiFeHCF-4, d LiFeHCF-2, and e LiFeHCF-1 powder samples. All images are taken from ex situ SEM measurements. f Schematic illustration of a microcrystalline crystallite size of LiFeHCF sample. g–k The corresponding capacity−voltage profiles of the LiFeHCF samples at specific current of 19 mA g−1. All LiFeHCF electrodes were evaluated in coin cell configuration using Li metal as counter electrode and tested at 25 °C.
