Mass transport plays an important role in the process of metal deposition and the charging/discharging kinetics in a rechargeable battery. The rational regulation of mass transport behavior to realize optimum ion‐transfer direction and rate can enable uniform metal nucleation and reduced concentration polarization, which is favorable for overcoming the dendrite growth and lithium plating issues in metal batteries and fast‐charging batteries, respectively. Here, recent progress in lithium metal batteries and fast‐charging batteries achieved through the mass‐transport regulation are summarized. An introduction of mass transport and a discussion of its decisive role in battery operation are provided, followed by an exploration of the correlation between mass‐transport regulation and battery performance. Some future perspectives and research directions for regulating mass transport to enable high‐performance rechargeable batteries are also discussed.
