摘要

With the rising demand for fast-charging technology in electric vehicles and portable devices,significant efforts have been devoted to the development of the high-rate batteries.Among numerous candidates,rechargeable aqueous zinc-ion batteries (ZIBs) are a promising option due to its high theoretical capacity,low redox potential of zinc metal anode and inherent high ionic conductivity of aqueous electrolyte.As the strong electrostatic interaction between Zn2+ and host generally leads to sluggish electrode kinetics,many strategies have been proposed to enhance fast (dis)charging performance.Herein,we review the state-of-the-art ultrafast aqueous ZIBs and focus on the rational electrode-designing strategies,such as crystal structure engineering,nanostructuring and morphology controlling,conductive materials introducing and organic molecule designing.Recent research directions and future perspectives are also proposed in this review.
