Regulating Mass Transport Behavior for High‐Performance Lithium Metal Batteries and Fast‐Charging Lithium‐Ion Batteries

Abstract

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.

Cryo‐Electron Microscopy for Unveiling the Sensitive Battery Materials

“…Thus, it is imperative to fully understand the characteristics of these materials at the micro-, nanometer, and even atomic scales. [41][42][43] Although the current characterization techniques have made us recognize that the formation of Li dendrites is to blame for the failure of LMBs, [11,44,45] there is insufficient knowledge about the microstructure and composition of Li dendrites up to now. Therefore, it is extremely difficult to study their structural characteristics, especially at the atomic scale.…”

Regulating lithium deposition behavior by electrokinetic effects in a high-zeta-potential h-BN/zinc-lithium alloy for high-performance lithium metal anodes

“…Li ions deposit preferentially along with the initial nuclei and develop on the surface of the nuclei upon their incorporation into the structure of the Li metal lattice. 20 Aerwards, the following deposition morphology is highly dependent on the Li-ion transport behavior and critical factors associated with Li-ion transport such as the transport rate, pathway and uniformity, directly inuence the ion concentration polarization, ion reduction kinetics and location, 21,22 and dominate the threshold time of Li-dendrite growth, as veried by Sand's model. 23,24 Many strategies have been reported to regulate Li-ion transport to achieve uniform Li deposition, such as structured/modied electrodes, [25][26][27][28] electrokinetic phenomena, 21,29 and a Li-ionaffinity matrix, [30][31][32] although the investigation of the Li nucleation process is not involved.…”

Among these strategies, electrokinetic phenomena including electroosmosis, electrophoresis and electrokinetic surface conduction are effective ways to enhance Li-ion transport kinetics.…”
