Characterization of the GO-g-PAM@PP separator. a Digital photograph of a bent GO-g-PAM@PP separator. b Cross-section and (c) top-view SEM images of the GO-g-PAM@PP separator. d SEM image of the uncoated side of the GO-g-PAM@PP separator. e Nyquist plots of symmetric Li|Li cells with PP, GO@PP, and GO-g-PAM@PP separators. f LSV curves of asymmetric Li|stainless-steel cells with PP, GO@PP, and GO-g-PAM@PP separators at a scan rate of 5 mV s−1. Scale bars: (b) 20 μm, (c) 5 μm, and (d) 1 μm
