摘　　要：The hierarchical porous nitrogen-doped carbon materials （HNCs） were prepared by using nitrogen containing gelatin as the carbon source and nano-silica obtained by a simple flame synthesis approach as the template. All of the as-obtained HNCs show much higher Li storage capacity as compared with commercial graphite. Specifically, HNC-700 with biggest micropore volume and highest nitrogen content exhibited optimal reversible capacities of 1084 mAh·g^-1 at the current density of 37.2 mA·g^-1 （0.1 C） and 309 mAh·g^-1 even at 3.72 A·g^-1 （10 C）. This result suggests that HNCs should be a promising candidate for anode materials in high-rate lithium ion batteries （LIBs）.The hierarchical porous nitrogen-doped carbon materials （HNCs） were prepared by using nitrogen containing gelatin as the carbon source and nano-silica obtained by a simple flame synthesis approach as the template.
