“…Furthermore, the ideal conductive frameworks should be equipotential so that Li ions can uniformly deposit on the surface at the same rate and avoid local uneven nucleation resulting from heterogeneous local current densities to form Li dendrites. According to the type of conductive materials, it can be classified to three categories: carbon‐based hosts, metal‐based hosts, and lithium‐based hosts …”

Rechargeable batteries are regarded as the most promising candidates for practical applications in portable electronic devices and electric vehicles. In recent decades, lithium metal batteries (LMBs) have been extensively studied due to their ultrahigh energy densities. However, short lifespan and poor safety caused by uncontrollable dendrite growth hinder their commercial applications. Besides, a clear understanding of Li nucleation and growth has not yet been obtained. In this Review, the failure mechanisms of Li metal anodes are ascribed to high reactivity of lithium, virtually infinite volume changes, and notorious dendrite growth. The principles of Li deposition nucleation and early dendrite growth are discussed and summarized. Correspondingly, four rational strategies of controlling nucleation are proposed to guide Li nucleation and growth. Finally, perspectives for understanding the Li metal deposition process and realizing safe and high-energy rechargeable LMBs are given.

“…electrochemical stripping and deposition on alkali-metal anodes and suppressing dendrite growth. For instance, employing a 3D conductive framework such as 3D Cu foil, 37 graphene-based material, 38 and carbon nanofibers 39,40 as the host not only effectively decreases current density but also buffers volume change. Compared to a conductive matrix, matrices with surface functional modification have also been developed to realize a dendrite-free morphology by distributing the alkali-metal ions on the surface of the anodes.…”

Alkali-metal batteries (AMBs) are one of the most promising candidates for next-generation high-energy battery systems. However, dendrite growth and serious safety implications limit the commercialization of AMBs. After years of development, the process of bringing alkali-metal anodes from lab to market is still full of tremendous challenges in terms of safety and cycle life. In this review, we divide the commercialization process of alkali-metal anodes into three stages: the first stage is fundamental researches on alkali-metal anodes, the second stage is the application of alkali-metal anodes in high-energy-density battery systems, and the third stage is satisfying the needs of industrialization. We mainly focus on the second and third stages and attempt to establish a relationship between academia and industry in this field. Finally, we give several perspectives on opportunities and challenges in the future development of AMBs for practical applications.

“…Xiang et al investigated Li metal deposition behaviors in CNT with various internal to external radius ratios ( R 0 : R 1 ) ranging from 8:10 to 1:10 ( Fig. 6 a) [75] . As observed by the SEM images of CNT after Li deposition at 1 mAh, it was found that as R 0 : R 1 reduced, Li atoms were preferentially deposited on the interior surface ( Fig.…”
