Abstract
A binder-free carbon nanofibres web over stainless-steel wafer current collector was fabricated by controlled pyrolysis of electrospun SU-8 photoresist nanofibres. Electrochemical performance of the as-prepared carbon nanofibres webwas investigated by performing charge-discharge experiments at different current densities. At lowcurrent density (37.2 mA g-1,0.1C), SU-8-derived carbon nanofabric showed a large initial discharge capacity (1417 mAh g-1) with sufficiently higher initial coulombic efficiency (∼55%). More importantly, this carbon nanofibres web also exhibited excellent rate performance with considerably higher specific capacities at higher current densities (358 mAh g-1 at 1C). This superior electrochemical performance, in particular at high current rates, can be attributed to small lithium ion diffusion length and resilience in entangled carbon nanofibres to accommodate volume changes during charging and discharging. © Indian Academy of Sciences.
