文摘

Super P (SP) consists of few-layer-thick graphite, interlayer distance ca. 0.357 nm. The graphitic layer distance increases on sodiation to ∼3.84 and 4.41 Å. Metallic Na plating were observed at the micro-pores between the carbon particles. Pathways of Na+ into graphite layers and micro-pores were proposed.
