Lithium metal is a promising anode material in batteries, owing to its high theoretical capacity (3860 mAh g −1) and low operating voltage (−3.04 V vs standard hydrogen electrode (SHE)). It can potentially result in higher energy density (≈500 Wh kg −1 ) than state-of-the-art graphite-based lithium-ion batteries (≈250 Wh kg −1 ). [ 2 ]

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.
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.
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.
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 anode side for LMBs, investigations have been introduced for the Li/Cu galvanic couple and continuous chemical and galvanic corrosion of the SEI causing the degradation of capacity [14, , , , , ]. Lithium corrosion in electrolytes involves one kind of direct charge transfer through the lithium-electrolyte interphase.
