Research progress towards the corrosion and protection of electrodes in energy-storage batteries

Energy storage batteries are central to enabling the electrification of our society. The performance of a typical battery depends on the chemistry of electrode materials, the chemical/electrochemical stability of electrolytes, and the interactions among current collectors, electrode active materials, and electrolytes. The interfacial interactions between (current collectors)/electrolytes and (electrode materials)/electrolytes involve corrosions that will affect the electrochemical performance of batteries. 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. In this review, we first summarize the recent progress of electrode corrosion and protection in various batteries such as lithium-based batteries, lead-acid batteries, sodium/potassium/magnesium-based batteries, and aqueous zincbased rechargeable batteries. It highlights the recent achievements in developing new stabilization strategies for the various batteries, critically focusing on Li-based batteries. The understanding of typical corrosion in batteries is helpful for us to find out protection strategies to build batteries with a longer lifetime.
