Al-Substituted Li[Li_(1/3-x/3)Cr_x-0.05M_0.05Mn_(2/3-2x/3)]O₂ Cathode Synthesized via Sol-Gel Process

Abstract:

This work reports the effect of doping aluminium in the Li[Li(1/3-x/3)Crx-0.05M0.05Mn(2/3- 2x/3)]O2 (x= 0.2; M= Al), layered cathode material. The cathode material was prepared by citric acid assisted sol-gel process. The sample is characterized by TG/DTA, XRD and FESEM measurements. The Al- doped cathode has delivered an initial discharge capacity of 250 mAh/g with a current density of 0.12 mA/cm2.
