Abstract
Synthesis and electrochemical properties of LiMn1/3Cr1/3Fe1/3O2 solid solution with the structure of α-NaFeO2
Incoming article date: 20.02.2014The solid solution of LiMn1/3Cr1/3Fe1/3O2 with the structure of α-NaFeO2 isostructural with the widely used LiCoO2 has been synthesized and investigated as a cathode material. Rated voltage of LiMn1/3Cr1/3Fe1/3O2 relative to the lithium is 4 V. The possibility of charging − discharging the material to a specific capacity of 220-250 mAh/g at currents of C/15-C/50 without phase transformations has been experimentally demonstrated.
