Abstract
A series of Li[CrxLi(1âx)/3Mn2(1âx)/3]O2 (0.15 â¤Â x â¤Â 0.3) cathode materials was prepared by citric acid-assisted, sol-gel process. Sub-micron sized particles were obtained and the X-ray diffraction (XRD) results showed that the crystal structure was similar to layered lithium transition metal oxides (R-3m space group). The electrochemical performance of the cathodes was evaluated over the voltage range 2.0-4.9 V at a current density of 7.947 mA gâ1. The Li1.27Cr0.2Mn0.53O2 electrode delivered a high reversible capacity of up to 280 mAh gâ1 during cycling. Li[CrxLi(1âx)/3Mn2(1âx)/3]O2 yielded a promising cathode material.
