Typically, granular-activated carbon held together by polymer binder is used. As a potential alternative, this paper focuses on the potential use of commercially available carbon fiber nonwovens. A commercially available binder-free carbon fiber nonwoven was used initially, but surface area analysis revealed that no microporosity developed following the CO2 activation treatment. In order to investigate how the structure of the original carbon material impacted subsequent activation, polyacrylonoitrile (PAN) nonwovens were fabricated and carbonized in-house under controlled conditions (695, 895, and 1095 °C). Carbonization temperature was found to be a limiting factor, where higher carbonization temperatures led to lower potential for activation. Since commercially available materials are typically carbonized at unknown temperatures, and are likely carbonized at high temperatures to develop electrical conductivity, it is found that they are unlikely to form high SSA materials.}, number={9}, journal={JOURNAL OF THE TEXTILE INSTITUTE}, author={Leary, Jennifer D. and Maze, Benoit and Pourdeyhimi, Behnam}, year={2017}, pages={1528–1536} }

However, the low electrical conductivity and large volume change during Li insertion/extraction of α-Fe2O3 hinder its use in practical batteries. In this study, carbon-coated α-Fe2O3 nanofibers, prepared via an electrospinning method followed by a thermal treatment process, are employed as the anode material for LIBs. The as-prepared porous nanofibers with a carbon content of 12.5 wt% show improved cycling performance and rate capability. They can still deliver a high and stable capacity of 715 mAh g−1 even at superior high current density of 1000 mA g−1 after 200 cycles with a large Coulombic efficiency of 99.2%. Such improved electrochemical performance can be assigned to their unique porous fabric structure as well as the conductive carbon coating which shorten the distance for Li ion transport, enhancing Li ion reversibility and kinetic properties. It is, therefore, demonstrated that carbon-coated α-Fe2O3 nanofiber prepared under optimized conditions is a promising anode material candidate for LIBs.}, journal={JOURNAL OF ALLOYS AND COMPOUNDS}, publisher={Elsevier BV}, author={Zhu, Jiadeng and Lu, Yao and Chen, Chen and Ge, Yeqian and Jasper, Samuel and Leary, Jennifer D. and Li, Dawei and Jiang, Mengjin and Zhang, Xiangwu}, year={2016}, month={Jul}, pages={79–85} }

Four types of CFF were initially tested for double layer capacitance before polyaniline deposition, and again for specific capacitance after deposition. A binder-free CFF was selected for further analysis due to its high capacitance change following PANI deposition (three orders of magnitude). The aniline monomer concentration, deposition potential, and deposition time were varied and resulting materials were characterized using chrono-potentiometry, cyclic voltammetry, and scanning electron microscopy. The deposition potential range yielding highest capacitance was found to be between 0.744 and 0.777 V. A solution concentration of 0.5M aniline at a 20 min deposition time resulted in the highest specific capacitance (>80 F/g based on total electrode mass and >300 F/g based on PANI mass) within this study. © 2015 Wiley Periodicals, Inc.
