| Abstract: | Nickel-based complex oxide Li_aNi_(0.7)Co_(0.3)O_2 was prepared with 3 different methods.It was studied that effect of synthetic methods of Li_aNi_(0.7)Co_(0.3)O_2 cathode materials on their performance.XRD investigated its structure.The results demonstrated that prepared cathode materials by the improved solid-state reaction synthetic method using coprecipitated Co-Ni hydroxides had an inferior cyclic performance and a higher dischargeable capacity.Its charged and discharged capacities were 196.5 and 167.9... |
