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
採用傳統共沉澱工藝在空氣氣氛中成功地合成出了二元lini1 - xalxo2 （ 0 < x 1 / 2 ）層狀固溶體系列，綜合考察了不同鋰源、預處理方式、鋰的配比量、焙燒溫度等條件對合成產物的結構和性能的影響，確定出了最佳合成工藝:以硝酸鋰為鋰源，超聲波作為分散動力源，鋰源與鎳鋁金屬鹽摩爾比為1 . 05 : 1 ， 700下焙燒16h的lini0 . 8al0 . 2o2樣品電化學性能最佳，在2 . 8 ~ 4 . 40v之間， 0 . 2c的倍率放電可逆容量達130 . 7mah ? g - 1 。 -
The results from simulation agree well with the conclusions of conference [ 21 ], and indicate that the boundary conditions have no obvious effect on the displacement and stress ; that the displacement and stress increase with linear heat expanding ratio, and those decrease with the specific heat of material ; that the displacement increases with the heat transfer ratio, but the stress does not
數值模擬表明：邊界條件對位移和應力的影響非常小；位移隨著線熱膨脹系數、熱傳導系數的增大而增大，但是隨著比熱容的增大而減小；應力的最大值隨著線熱膨脹系數的增大而增大，而隨著比熱容的增大而減小，而熱傳導系數k對應力的影響比較小。
