Electrode materials as well as the electrolytes play a decisive role in batteries determining their performance, safety, and lifetime. In the last two decades, different types of batteries have evolved. A lot of work has been done on lithium ion batteries due to their technical importance in consumer electronics, however, the development of post-lithium systems has
During the discharge process, the electrolyte''s density decreases due to the consumption of sulfuric acid and the production of water. The charging process, on the other hand, represents the reverse process in which current is supplied to the battery to ensure that the PbSO 4 is converted back into Pb and PbO 2 at the negative and positive poles respectively,
However, Zn anodes suffer from serious problems such as dendrite growth, hydrogen evolution reaction, corrosion, and passivation. Cu-based materials have a wide range of applications in Zn anodes due to their excellent zincophilicity. Unfortunately, relevant review on Cu-based materials in anode electrode is still lacking.

The critical aspects of the corrosion of metal electrodes in cathodic reductions are covered.

Silicon (Si) is recognized as a promising candidate for next-generation lithium-ion batteries (LIBs) owing to its high theoretical specific capacity (~4200 mAh g−1), low working potential (<0.4 V vs. Li/Li+), and abundant reserves.

All in all, electrode corrosion urgently needs to be taken into great consideration in battery degradation. The modification of electrolyte components and electrode interface are effective methods to improve the corrosion resistance for electrodes and the lifetime performances.
On the cathode side, the corrosion of the Al current collector and the generation of the cathode electrolyte interface (CEI) are electrolyte corrosion reactions in the battery. On the anode side, the solid electrolyte interface (SEI) and galvanic couple between the anode materials and the Cu current collector are shown in Fig. 2 d-e.
But the results still show that electrode corrosion is the main factor to shorten the working life of batteries. In general, electrode corrosion results in the dissolution of active materials/current collectors, oxidation/passivating of current collectors, and defects of electrodes.
In a battery, corrosion commonly stems from the dissolution/passivation of electrode active materials and dissolution/oxidation/passivation of current collectors. Since the evolution of battery research is fast, a comprehensive review of battery corrosion is necessary.
However, corrosion has severely plagued the calendar life of lithium batteries. The corrosion in batteries mainly occurs between electrode materials and electrolytes, which results in constant consumption of active materials and electrolytes and finally premature failure of batteries.
