AI Customer ServiceIn a battery, on the same electrode, both reactions can occur, whether the battery is discharging or charging. 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 normal use of a rechargeable battery, the potential of the positive electrode, in both discharge and recharge, remains greater than the potential of the negative electrode. On the other hand, the role of each electrode is switched during the discharge/charge cycle. During discharge the positive is a cathode, the negative is an anode.
Lithium is the third element in the periodic table. It has the most negative electrode potential and is stable only in non-aqueous electrolytes. It was not popular electrode material in battery community before 1970. Purification of organic solvents and lithium salts to remove water was especially hard work in each laboratory.
The phosphate positive-electrode materials are less susceptible to thermal runaway and demonstrate greater safety characteristics than the LiCoO 2 -based systems. 7. New applications of lithium insertion materials As described in Section 6, current lithium-ion batteries consisting of LiCoO 2 and graphite have excellence in their performance.
For example, silicon (Si) is a promising alternative candidate electroactive material for batteries due to its higher capacity (4200 mAh × g −1) . In this review article, 6 rechargeable battery types were presented to understand the effects of electroactive materials.
Lithium metal was used as a negative electrode in LiClO 4, LiBF 4, LiBr, LiI, or LiAlCl 4 dissolved in organic solvents. Positive-electrode materials were found by trial-and-error investigations of organic and inorganic materials in the 1960s.
