摘要：
A wax gourd flesh-derived porous carbon material has been prepared using different activating agents through the pyrolysis carbonization method. The materials activated by CaCl2 and KOH were marked as WGF-CaCl2 and WGF-KOH, respectively. The WGF-CaCl2 and WGF-KOH materials have lamellar structures that small particles randomly distribute on the pleats. Compared with the WGF-CaCl2, the WGF-KOH material takes on a higher specific surface area. The WGF-CaCl2 and WGF-KOH materials have different lithium storage performances. The first discharge capacity (152.2/776.6 mAh g−1), the cycling capacity and the rate retention capacity of the WGF-KOH are higher than that of the WGF-CaCl2 because the WGF-KOH material has more micropores, a high-specific surface area and a high Si content.
