This thesis focuses on the study of the layered lithium nickel - based oxides as catho de materials lithium - ion batteries , the main aspects follow : 1 study on the synthesis and properties of linixco1 - xo2 by the sol - gel method compared with solid - state method , sol - gel method enjoys the advantage of lower calcining temperature and small uniform particle size of products . after the xrd measurement , it was shown that the single - phase layered compound can be prepared in sintering temperature of 750 for 6 ~ 8 hours . the sintering temperature , the properties and the amounts of doping materials can all affect the product ' s phase , and its structure ( lattice parameter , crystal phase distance )
本论文的研究工作主要集中在作为锂离子电池正极材料的层状锂镍基氧化物上，包括以下几个方面： 1溶胶凝胶法( sol - gel )合成lini _ xco _ ( 1 - x ) o _ 2的研究与固相合成法相比，溶胶凝胶法合成lini _ xco _ ( 1 - x ) o _ 2煅烧温度低，产物颗粒均匀一致，经过xrd的测试过后，结果表明750下烧结6 8小时，即可得到单相产物；烧结温度，掺杂剂的种类及掺杂剂量均对产物物相的形成产生影响，并对产物的结构产生影响。
