摘要

The past decade has witnessed the germination of rechargeable aluminum batteries (RABs) with the colossal potential to enact as a device for the large scale energy storage and conversion,The Majority of investigations are dedicated to the exploration of suitable cathode materials,while less is known about the electrode/electrolyte interfaces that determine the electrochemistry of batteries.In this perspective,we will highlight the significance of electrode/electrolyte interface for RABs,in overall kinetics and capacity retention.Emphasis will be laid on the complicated yet basic understandings of the phenomena at the interfaces,including the dendrite growth,surface Al2O3 and solid-electrolyte-interphase (SEI).And we will summarize the reported practice in effort to build better electrode/electrolyte interfaces in RAB.In the end,outlook regarding to the challenges,opportunities and directions is presented.
