Learn MoreIn 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.
The terminology of corrosion in battery research dates back to 1979 when Peled et al. described the solid-electrolyte-interphase (SEI, i.e., a layer of corrosion product) at the Li metal–liquid electrolyte interface 19.
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.
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.
MIBs and MABs have been the most studied batteries for various corrosion issues in the last decade. A few works were reported on Pb-acid, Ni-metal hydride (Ni-MH), redox flow, and other types of batteries. Only a few recent reports are available on corrosion in Pb-acid and Ni-MH batteries.
The phenomena can be clarified as electrode corrosion, which is particularly serious in Ni-rich cathode-based batteries. It is widely acknowledged that lower-valence-state metal ions have a higher solubility in the electrolyte than higher-valence-state ones.
