Two types of solid solution are known in the cathode material of the lithium-ion battery. One type is that two end members are electroactive, such as LiCo x Ni 1−x O 2, which is a solid solution composed of LiCoO 2 and LiNiO 2.The other type has one electroactive material in two end members, such as LiNiO 2 –Li 2 MnO 3 solid solution. LiCoO 2, LiNi …
When naming the electrodes, it is better to refer to the positive electrode and the negative electrode. The positive electrode is the electrode with a higher potential than the negative electrode. During discharge, the positive electrode is a cathode, and the negative electrode is an anode. During charge, the positive electrode …
