CrxV6O13(x =0.01~0.05) cathode materials were prepared using NH4VO3 and Cr2O3 as raw material by solid phase method in argon atmosphere.
Introduction Since Murphy [1] first reported that V6O13 could be used as cathode materials for lithium ion batteries, V6O13 has become one of research hot spots on cathode materials.
CrxV6O13 cathode materials were prepared by following process.
Unlike other lithium ion battery cathode materials like LiCoO2, all Li/V6O13 cells are first discharged.
