It should be noted that the potential applicability of this anode material in commercial lithium-ion batteries requires a careful selection of the cathode material with sufficiently high voltage, e.g. by using 5 V cathodes LiNi 0.5 Mn 1.5 O 4 as positive electrode.
During discharge, the positive electrode is a cathode, and the negative electrode is an anode. During charge, the positive electrode is an anode, and the negative electrode is a cathode. An oxidation reaction is an electrochemical reaction that produces electrons.
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.
During discharge the positive is a cathode, the negative is an anode. During charge the positive is an anode, the negative is a cathode. Texts describing battery anodes or cathodes certainly implicitly consider the case of the discharge. Let us not hesitate to write, paraphrasing Rutherford, implicit is nothing but poor explicit.
Lithium manganese spinel oxide and the olivine LiFePO 4 , are the most promising candidates up to now. These materials have interesting electrochemical reactions in the 3–4 V region which can be useful when combined with a negative electrode of potential sufficiently close to lithium.
In 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.
