1. Introducing lithium batteries
It has become common practice, particularly in the case of lithium batteries, to refer to the positive electrode as the cathode and the negative as the anode. We know that a positive electrode is alternately cathode and anode during a cycle consisting of discharge followed by charge (see § 2.3 and Figure 7 in the Theoretical Considerations chapter). ), while the situation is reversed for a negative. The term "usage" therefore refers to discharge operation.
Of course, the selection of high-performance anode and cathode materials is not a matter of chance. First of all, researchers take into consideration the standard potential of the electrode material and its mass capacity. We know that the standard electrode potential is negative for reducing bodies (anode materials) and positive for oxidizing bodies (cathode...
