Abstract The unique structural features of hard carbon (HC) make it a promising anode candidate for sodium‐ion batteries (SIB). However, traditional methods preparing HC require special equipment, long reaction times, and large energy consumption, resulting in low throughputs efficiency. In our contribution, novel synthesis method is proposed, involving the formation nanosheets (NS‐CNs) within minutes by creating an anoxic environment through flame combustion further introducing sulfur...
In this paper, coal asphaltene/polyacrylonitrile based nitrogen doped porous carbon membrane (NPCM) was prepared by electrospinning using SBA-15 as hard template agent. The effects of raw material composition and carbonization temperature on the yield, specific surface area capacitive properties were studied. When mass ratio SBA-15:asphaltene:polyacrylonitrile=1:1.2:4.8, yield (58.7%) (427.6m<sup>2</sup>/g) NPCM2 higher. capacitance reaches 214.2F/g. After 10000 times charge discharge at...
Traditional methods in preparation of hard carbon (HC) requires special equipment, long reaction times, and large energy consumption, resulting low throughputs efficiency. In our contribution, a novel synthesis method is proposed, involving the formation HC nanosheet within minutes by flame combustion air, further introduction sulfur nitrogen sources to achieve heteroatom doping. It was confirmed HRTEM, XPS, EPR, Raman that prepared are rich defects, pores functional groups. Combined with...
Although sodium-ion capacitors (SICs) hold great application potential in the areas where energy and power output are both highly required, they still encounter challenges to design suitable anode materials with quick dynamics provide high output. In present work, ultra-thin porous carbon nanosheet (PCS) combing structure advantage of soft (ordered nature) hard (amorphous was successfully designed, which facilitates charge transport Na+ migration thus guarantees high-rate capacity long cycle...
