- Abstract
Hierarchical porous carbon nanosphere (HPCN) was synthesized through the aldimine condensation between glutaraldehyde (GA) and 3-aminopropyltriethoxysilane (KH-550) followed by subsequent calcination and NaOH etching. Scanning electron microscopy (SEM) experiments showed that HPCN displays monodispersed nanospherical structure with an average diameter of 85.3 nm. HPCN/S cathode material was prepared by a melt-diffusion method and assembled into coin cells to conduct electrochemical test. HPCN/S material exhibited excellent electrochemical performance with a discharge capacity of 472.1 mA·h/g after 100 cycles at 0.2 C when using aluminium foil as current collector. When carbon paper collector was applied instead of aluminium foil, HPCN/S-CP cathode exhibited much more excellent cycling stability and rate performance with a discharge capacity of 636.1 mA·h/g after 100 cycles at 0.2 C, and rate capabilities of 702.7 mA·h/g and 249.4 mA·h/g at 1.0 C and 2.0 C respectively.
