Abstract Porous copper, as an anode collector for lithium metal batteries, has excellent conductivity, a huge surface area and good economic cost-effectiveness. In the process of charging and discharging, there are problems such as uncontrolled growth of lithium dendrites and the shedding of dendrites into "dead lithium", thus reducing the capacity, which seriously affects the battery’s lifespan and cycling stability, whereas the 3D structure of the porous copper foil can effectively alleviate the problem of dendrite growth, and the large number of pore spaces on the surface and in the interior greatly increases the space to accommodate the active substance, the high curvature of the pore edges makes the current density in this region higher, which can induce lithium deposition to the inside of the pores, effectively avoiding lithium dendritic growth on the surface, and the lithophilic modification can reduce the overpotential of lithium nucleation on metallic copper, effectively stabilizing the lithium deposition behavior. This paper introduces the current research status of porous copper as anode collector for lithium metal batteries and its preparation method of lithophilic modification of copper foil, analyzes the lithium storage mechanism of porous copper and the advantages of lithophilic modification, looks forward to the application prospect of porous copper collector, and points out the problems existing in the current research.

Key words： porous copper current collector dealloying lithophilic modification lithium metal battery
