In this work, layered lini1 - xalxo2 ( 0 < x 1 / 2 ) solid solution materials were successfully synthesized by current co - precipitation method in the air, and their preparation and properties were deeply and systematically explored. influences of different factors on the structure and properities of samples were studied, including li resources, different performs, li / m ( oh ) 2 molar ratio, calcining heat condition, the best synthesis technics were concluded : sintered for 16h at 700 from li source ( lithium nitrate ) : m ( oh ) 2 = 1. 05 : 1, ultrasonic vibration for dispersing and catalysing are best. lini0. 8al0. 2o2 exhibited a discharge capacity of 130. 7 mah ? g - 1 in the voltage range of 2. 8 ~ 4. 40v and at a specific current of 0. 2 c. a new co - precipitation method was proposed, it included ultrasonic for dispersing and catalysing, by dropping lioh to the aqueous solution of metal nitrates, hydroxides of metals were precipitated and the resulting solution was evaporated as received
