Electrochemical Behavior of LiCo_(1-x)Mn_xO₂ Crystalline Powders

Abstract:

LiCoO₂ is a well-known cathode material used in commercial Li-ion batteries but it has its own limitations in terms of cost and toxicity. Improvement of the material by partial substitution of Co with other transition metals is one of the alternative and effective ways to overcome the limitations and improve the electrochemical performance of cathode materials. The transition metal element used for the substitution has to be cheaper and non-toxic thus Mn is chosen here. LiCo_(1-x)Mn_xO₂ (x= 0.1, 0.2, 0.3) we synthesized by a novel route using a self-propagating combustion (SPC) method. The samples are analyzed using X-Ray Diffraction (XRD) for phase purity and Field Emission Scanning Electron Microscopy (FESEM) for morphology and particle size studies. The materials obtained are phase pure. In terms of electrochemical activity, though it does not show better first cycle discharge capacity, the Mn doped materials have improved capacity retention. Results showed that LiCo_0.9Mn_0.1O₂ and LiCo_0.8Mn_0.2O₂ exhibited less than 8 % capacity loss in the 20th cycle compared to 12 % for LiCoO₂.
