Due to its highest theoretical capacity and its lowest redox potential,lithium(Li)metal has been considered as the ultimate anode choice for high-energy-density rechargeable batteries.However,its commercialization is severely hindered by its poor cyclic stability and safety issues.Diverse material structure design concepts have been raised to address these failure models,wherein,hollow structure has shown great power in solving the challenges.Especially,a hollow multishelled structure(HoMS)featured with two or more shells has been proved to be more efficient to improve Li metal anode than their single-shelled counterparts.Herein,this up-to-date review summarizes the recent progress of the application of HoMS in Li metal anode,including their adoption as Li metal host,artificial solid electrolyte interphase film,electrolyte additive,solid state electrolyte,etc.HoMS offers unique advantages,such as suppressing Li dendrite growth,stabilizing electrode-electrolyte interface,and improving overall battery performance.Future research directions are outlined,emphasizing the need for multifunctional integrated smart HoMS design and large-scale fabrication of HoMS through low-cost accurate method to further advance the commercialization of Li metal batteries.
