The invention discloses a negative electrode-free lithium metal battery, a negative electrode current collector and a preparation method thereof. The negative electrode current collector comprises a negative electrode current collector matrix and an ion conductive layer, an electronic conductor layer or an ion-electronic hybrid supported on the negative electrode current collector matrix. conductor layer. The negative electrode current collector prepared by the invention has good lithiophilic properties, or can be alloyed with lithium to have a lower nucleation barrier, or can form an ionic conductor, form a stable lithiophilic SEI layer, and effectively improve lithium The deposition morphology, or the formation of mixed ion conductors, can control the uniform deposition of lithium in many aspects, and finally achieve uniform lithium deposition and high electroplating/stripping efficiency, effectively improving the cycle performance of anode-free batteries. |
