It is essential to investigate lithium dendrite growth for the commercial application of lithium metal batteries. Here, phase field modeling of lithium dendrite growth is performed by taking into consideration of the effects of anisotropy strength, applied voltage, nucleation spacing, and stripping first or not. Compared with constant-voltage charging mode, the lithium dendrite growth is slower and the formed lithium dendrites are shorter and narrower shapes under the pulse-voltage charging mode. These results provide an instructive insight to restrain the undesired growth of lithium dendrites.
