Description	Journal: Materials Research Express LiMn2O4 and its rare earth dopant materials have acquired significance much among all the cathode materials. It is due to their vast advantages in physical and chemical properties such as cost effective materials, low toxicity, high tensile strength and high power density. Spinel oxides of LiCrxMn2-xO4 (x = 0.1 and 0.15) have been prepared by doping pure LiMn2O4 with chromium ions by solid state reaction method. XRD revealed that the prepared samples possess a cubic spinel phase. The little agglomeration of particle in the samples increases by increasing the dopant concentration and it is found to be from 50 to 250 nm. LiCrxMn2-xO4 (x = 0.15) exhibited better electrochemical cycling when it is compared to LiMn2O4. Charge and discharge curves showed that the LiCrxMn2-xO4 (x = 0.15) cathode material have the highest discharge capacity (147.2 mAh/g) when compared to the other samples, which was due to increased polarization at higher current rates. Thus the sample LiCrxMn2-xO4 (x = 0.15) can be used as cathode material in rechargeable battery applications.
