The limited capacity and long charging time of graphite-based anodes for lithium-ion batteries cannot meet ever-growing demands. Developing anodes with a high capacity and a fast charging ability becomes a hotspot of the present research. Herein, an N-doped porous hard carbon (N-HC) was prepared via dehydration reaction of sucrose and sulfuric acid and subsequent annealing in NH3/Ar. The diffusion coefficient of Li+ in N-HC reaches 9.0×10-8 cm2·s-1 due to the rich ultra-micropore structure (i.e., pore size <0.75 nm) and the large interlayer spacing (i.e., 0.39 nm) in N-HC. The capacity of N-HC remains 704.0 mA·h·g-1 or 269.2 mA·h·g-1 after 680 or 1 400 cycles at 0.27 C or 2.7 C (1 C=370 mA·g-1). The N-HC electrode can meet the requirement of fast charging lithium-ion battery, while the initial Coulomb efficiency needs to be improved.
