Abstract
Porous carbon has been proven to be an auspicious anode material for sodium-ion batteries (SIBs), but the previous preparation methods still have shortcomings such as high cost, complicated processes, and environmental pollution. In this work, a biomimetic mineralization synergistic combustion activation strategy, which has the advantages of abundant raw materials, simple synthesis and environmental friendliness. The synthesized CMFO, with honeycomb morphology, high porosity and N, O, S triple doping, exhibits a 76.1 % initial coulombic efficiency when used as a sodium-ion battery (SIB) anode in an ether-based electrolyte. In addition, it can provide a specific capacity of 408.9 and 144.5 mAh g−1 at 0.05 and 10 A g−1, and retains a specific capacity of 151.4 mAh g−1 after 2000 cycles at 5 A g−1. Furthermore, the assembled NVP//CMFO full cell presents a high energy density of 177.7 Wh kg−1. This study demonstrates the excellence of the method in constructing anode materials for SIBs, and will inspire more researchers to use biomimetic mineralization template to develop more novel carbon-based materials to advance the field of energy storage.
期刊介绍:
The journal Carbon is an international multidisciplinary forum for communicating scientific advances in the field of carbon materials. It reports new findings related to the formation, structure, properties, behaviors, and technological applications of carbons. Carbons are a broad class of ordered or disordered solid phases composed primarily of elemental carbon, including but not limited to carbon black, carbon fibers and filaments, carbon nanotubes, diamond and diamond-like carbon, fullerenes, glassy carbon, graphite, graphene, graphene-oxide, porous carbons, pyrolytic carbon, and other sp2 and non-sp2 hybridized carbon systems. Carbon is the companion title to the open access journal Carbon Trends. Relevant application areas for carbon materials include biology and medicine, catalysis, electronic, optoelectronic, spintronic, high-frequency, and photonic devices, energy storage and conversion systems, environmental applications and water treatment, smart materials and systems, and structural and thermal applications.
