Summary: A molybdate conversion coating (MCC) has been developed to address corrosion of the aluminum current collector (AlCC) in commercial LiPF6-ester electrolytes. The MCC shows a compact structure and good combination with the AlCC matrix, reducing corrosion current density significantly. In Li parallel to NMC333 cells, the MCC-AlCC cathode cell demonstrates significantly higher capacity retention at high voltage compared to the control cell due to the stable artificial passivation layer preventing corrosion.

Summary: Effective passivation of aluminum current collector at high potentials is crucial for the long-term operation of lithium-based batteries. However, the non-aqueous liquid electrolytes used in these batteries are corrosive towards aluminum, despite their other desirable features. This study proposes the use of DMFSA as an electrolyte solvent to suppress aluminum corrosion, and demonstrates that it leads to significantly reduced corrosion and improved stability of the current collector.

Summary: The continuous electrochemical dissolution of anode in ionic liquid at room temperature is significant for electrorefining. The electrochemical dissolution behavior of an aluminum anode in [Emim]ClAlCl3 ionic liquid with O2-ion was investigated. It was found that the dissolved process of the aluminum anode and electrodeposition of insulated darkness Al-O-Cl species exist together at a relatively low potential. The Al-O-Cl species prevent the continuous dissolution of the aluminum anode, but it can be electrochemically dissolved at a higher potential, ensuring continuous dissolution.
