a Cyclic voltammetry curves of LiFeHCF-1 sample at different scanning rates. b Rate performance of LiFeHCF samples at various specific currents. c Cycling performance of LiFeHCF samples at 190 mA g−1. d Long-term cycling of LiFeHCF-1 material at 1.9 A g−1. e High-loading performance (10 mg cm−2). f, g High and low temperature tests at 55 °C and −20 °C. All LiFeHCF electrodes were evaluated in coin cell configuration using Li metal as counter electrode and tested at 25 °C (except where differently indicated). The specific capacity values were calculated base on the mass of positive electrode active material.
