Li metal has been attracting increasing attention as an anode in all-solid-state batteries because of its lowest electrochemical potential and high capacity, although the problems caused by dendritic growth impedes its further application. For a long time, all-solid-state Li metal batteries (ASLBs) are regarded to revive Li metal due to high mechanical strength. However, numerous works revealed that the dendrite issue widely exists in ASLBs, and the mechanism is complex. This review provides a systematic and in-depth understanding of the thermodynamic, kinetic, electrochemical, chemomechnical, structural stability, and characterizations of Li dendrite in ASLBs. First, the mechanisms for dendrite formation and propagation in polymer, ceramic and glass electrolyte were discussed. Subsequently, based on these mechanisms of dendrite growth, we reviewed various strategies for dendrite suppression. Furthermore, advanced characterization techniques were reviewed for better understanding of dendrite in solid-state batteries.

尽管由于树枝状生长引起的问题阻碍了它的进一步应用，但由于其最低的电化学势和高容量，锂金属作为全固态电池中的负极一直受到越来越多的关注。长期以来，由于高机械强度，全固态锂金属电池（ASLB）被认为可以使锂金属再生。但是，大量的工作表明，ASLBs中广泛存在枝晶问题，其机理很复杂。这篇综述提供了对ASLBs中Li枝晶的热力学，动力学，电化学，化学，结构稳定性和表征的系统且深入的了解。首先，讨论了树枝状晶体在聚合物，陶瓷和玻璃电解质中形成和扩散的机理。随后，基于这些枝晶生长机制，我们回顾了抑制枝晶的各种策略。此外，对先进的表征技术进行了综述，以更好地了解固态电池中的枝晶。
