摘　　要：采用柠檬酸盐法得到了不同Al、Mg掺杂量的LiNi1-x-yAlxMgyO2(x=0-0．25,y=0-0．06)固溶体材料．利用XRD对样品进行了测试分析．结果表明,各样品均具有α-NaFeO2型单相结构,形成了LiNi1-x-y AlxMgyO2固溶体单相．随着Al、Mg固溶量x、y的增加,材料的晶胞参数发生规律变化．Abstract： We synthesized LiNii-x-yAlxMgyO2（x=0～0.25,y=0～0.06） solid solutions of different A1 and Mg doption by citrate precursor method. From XRD results we found that all the samples crystallized in the α - NaFeO2 structure and formed LiNii-x-yAlxMgyO2 solid solutions. Doping with the increasing of A1 solu- tion x and Mg solution y, the lattice parameters of the materials have changed regularly.
