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.
The above-mentioned electrode corrosion eventually would point to the rapid failure of a battery. Especially, galvanic corrosion with gas generation can be a serious issue at the battery level, especially for the pouch battery with low-operating pressure demand .
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.
As a consequence of corrosion, the cathode materials lose electrical and mechanical contact with the current collector, leading to capacity and power fading. Therefore, a deeper understanding of this process and effective corrosion inhibition are necessary to prevent the deterioration of the battery performance.
Metal-ion and metal-air batteries are the most extensively investigated battery types. In Li-ion batteries, most of the corrosion-related works were reported on the corrosion of current collectors and its various mitigation approaches through electrode design modifications, surface coatings and electrolyte optimization.
The most studied battery types in terms of their component corrosion and degradation are MIBs and MABs, followed by redox-flow, lead-acid and metal-hydride batteries. Among the MIBs, the maximum investigated type of corrosion is the corrosion of current collectors. In MABs, most works focused on anode corrosion.
