The homogenous precursor has been prepared using a mixed aqueous solution of Ni(NO3)2·6H2O, Co(NO3)2 6H2O, Mn(NO3)2 and LiNO3 as metal sources and citric acid as chelating agent and fuel. The nanocrystalline LiNi1/3Co1/3 Mn1/3O2 powder was rapidly synthesized by deflagrating the dried precursor in oxygen. The annealed LiNi1/3Co1/3ln1/3O2 powder was mainly consisted of particle agglomerates with the primary particles size of 100～300 nm. The high initial capacities of 208.0 mAh·g-1 (2.8～4.6 V) and 173.6 mAh·g-1 (2.8～4.3 V) were discharged at the rate of 0.05 C respectively. Its capacity retentions were 89.3％ and 93.4％ within the voltage range of 2.8～4.6 V and 2.8～4.3 V at 0. 1 C after 20 cycles respectively.%以Ni(NO<,3>)<,2>·6H<,2>O、Co(NO<,3>)<,2>·6H<,2>O、Mn(NO<,3>)<,2>和LiNO<,3>为金属原料,以柠檬酸为鳌合剂和燃料制备出均一的前驱体.前驱体经干燥后在氧弹中快速爆燃制备出纳米LiNi<,1/3>Co<,1/3>Mn<,1/3>O<,2>粉体,并生成了高结晶度的LiNi<,1/3>Co<,1/3>Mn<1/3>O<,2>材料,其平均粒径约为200nm.将其分别在2.8～4.6V和2.8～4.3V电压范围内以0.05C速率恒流充放电,首次放电比容量分别为208.0mAh·g<'-1>和173.6mAh·g<'-1>;以0.1C速率分别在2.8～4.6V和2.8～4.3V电压范围内循环20周后,容量保持率分别为89.3%和93.4%.
