锂金属电池三维集流体设计研究进展OA北大核心CSTPCD

Lithium metal has a great potential in the field of energy storage due to its high theoretical capacity. However,the lithium dendrites caused by the uneven deposition of lithium metal in lithium metal batteries,may cause battery short circuits and restrict their current practical application. Three-dimensional current collector,due to their high specific surface area and abundant lithiophilic sites,can control lithium metal deposition through kinetic principles,thereby reducing local current density and improving lithium ion transfer rate and metal nucleation rate. In this paper,the research progress of 3D current collector in lithium metal batteries including metal,carbon,composites and the modification of 3D current collector in recent years were reviewed,and some issues needed to be solved and future developments in the field were also discussed.
