Direct synthesis of LiNi_1/3Co_1/3Mn_1/3O₂ from nitrate precursors

Two novel methods for synthesis of the title compound directly from metal nitrates are described. Phase-pure materials are produced when precursors are calcined between 600 and 1000 °C, with little to no ion mixing exhibited for products heated to 900 °C or above. The electrochemical characteristics of these materials depended upon calcination temperature and synthesis method, with results comparable to a commercial sample for the materials made at high temperatures in a one-step process without combustion. The sample prepared by combustion also exhibited very stable capacity retention upon cycling.
