LiNiO2-Based Positive Electrode Materials

Chenglin Hu, Xiangyun Yuan, Yuping Wu, and Teunis van Ree

At first, lithium-ion batteries used LiCoO2 as the positive electrode material. However, the natural sources of Co are limited, and it is expensive. As a result, the application field of lithium-ion batteries is very limited, and it is necessary to develop other kinds of positive electrode materials with high performance and low cost. LiNiO2 is one possible alternative for LiCoO2 as a positive electrode material for lithium-ion batteries [1]. Its practical capacity can be 190–210 mAh/g, which is much higher than that of LiCoO2, and its effect on the environment is much less adverse.
