Figure 10. Cycle performance of Li symmetric cells using 3DHM API/PVDF and PP with a current density of 0.2 mA cm^-2 (A) and 1.0 mA cm^-2 (B). SEM images of the surface of the cycled lithium foil in the symmetrical lithium metal cells at 0.2 mA cm^-2 for 60 cycles with (C) 3DHM API/PVDF and (D) PP films.
