The Li metal anode possesses the high specific capacity and minimum reduction potential known as renaissance of high-energy-density battery. However, security problems brought by uncontrolled dendrites have hindered its development. Integrating with non-flammable solid-state electrolytes (SSEs) provides a promising approach to solve problem achieve safe batteries. recent studies indicate that still occur in interior inorganic SSEs, although mechanical strength SSEs can resist dendrite growth theory. In this review, main causes within are summarized. Combined advanced characterization techniques theoretical calculations, models clarified. Furthermore, various strategies for suppressing comprehensively Finally, research prospects dendrite-free all-solid-state batteries evaluated.
