]. LiNiO2 is another cathode material candidate and also attracts much attention due to its low cost and the possibility of larger capacity than LiCoO2 in practice (LiCoO2, 140mA·h/g; LiNiO2, 200mA·h/g)[4.... The mixture was calcined to obtain the cathode material LiCoxNi1-xO2. The contents of Ni and Co in the alloys and the electrolysis products are listed in Table 1. As can be seen, the ratio of Ni to Co......
