Synthesis and Study on Physical Properties of Li-Inserted Cathode Materials LixMn3-xO4 and LiFeO2
In this work, lithium ion battery cathode material LixMn3-xO4(X = 0.7, 1.0, 1.2, 1.4, 1.6) and LiFeO2 were synthesized by a sol-gel method. At the same time, the structure, magnetism and electro-chemical performance of samples were studied. The results showed that LixMn3-xO4 were spinel structure and showed paramagnetic properties at room temperature. The initial charge-discharge capacities of sample with x = 1.2 were 58.16 mA∙h/g and 29.47 mA∙h/g. LiFeO2 sample with space group Fm3m exhibited a α-NaFeO2 ferrites structure, show soft magnetic properties at room temperature. The initial charge-discharge capacities of LiFeO2 sample were 80.95 mA∙h/g and 38.50 mA∙h/g. The relationship between the structure, the magnetism and electrochemical performance of series samples was analyzed deeply, which provided experimental basis for improving the capacity, stability and charge-discharge capacity properties of lithium cathode material.
