Nano-carbon-based materials are widely reported as lithium host materials in lithium metal batteries (LMBs); however, researchers report contradictory claims as to where the lithium plating occurs. Herein, the use of pure hollow core-carbon spheres coated on Cu (PHCCSs@Cu) to study the lithium deposition behavior with respect to this type of structure in lithium anode-free cells is described. It is demonstrated that the lithium showed some initial and limited intercalation into the PHCCSs and then plated on the external carbon walls and the top surface of the carbon coating during the charging process. The unfavorable deposition of lithium inside the PHCCSs is discussed from the viewpoint of lithium-ion transport and lithium nucleation. The application potential of PHCCSs and the data from these LMB studies are also discussed.
纳米碳基材料作为锂金属电池（LMBs）中的锂宿主材料被广泛报道；然而，研究人员对于锂电镀发生的位置存在相互矛盾的说法。在此描述了使用涂覆在铜上的纯空心碳球（PHCCSs@Cu）来研究无锂阳极电池中这种结构的锂沉积行为。结果表明，在充电过程中，锂最初有一些有限的嵌入到PHCCSs中，然后电镀在外部碳壁和碳涂层的顶表面上。从锂离子传输和锂成核的角度讨论了锂在PHCCSs内部不利沉积的情况。还讨论了PHCCSs的应用潜力以及这些LMB研究的数据。
