Case Study

Carbon Nanofiber (CNF) Used for the Fabrication of CuO/CNF Composite Anodes for Lithium-Ion Batteries

Tatar, Dhiraj Kishor, Yash Jaiswal, and Sunder Lal Pal. Materials Letters (2025): 138841.

Carbon nanofibers (CNFs) have emerged as advanced structural matrices for enhancing electrode performance in lithium-ion batteries (LIBs). In this study, CNFs were used to encapsulate CuO nanoparticles (CuO-NPs), forming a CuO/CNF composite with excellent electrochemical properties as an anode material.
The composite was synthesized by first dissolving polyacrylonitrile (PAN) in N,N-dimethylformamide (DMF), followed by the incorporation of CuO-NPs into the homogeneous PAN solution. This precursor solution was electrospun under optimized conditions (15-20 kV voltage, 0.5 mL/h flow rate, 15 cm tip-to-collector distance) to form nanofiber mats, which were subsequently carbonized at 800 °C in a nitrogen atmosphere. The resulting CNFs effectively encapsulated CuO-NPs, ensuring uniform dispersion and improved conductivity.
During battery operation, CuO undergoes reversible conversion reactions with lithium, while the CNF matrix facilitates electron transport and lithium-ion diffusion. Importantly, the robust carbon network mitigates volume expansion and maintains structural integrity during cycling, thereby enhancing the capacity and cycle life of the anode.
This work demonstrates the critical role of carbon nanofibers in composite electrode design, enabling the fabrication of high-performance CuO/CNF anodes for next-generation lithium-ion batteries. CNFs not only serve as conductive scaffolds but also significantly improve mechanical and electrochemical stability during repeated charge-discharge cycles.

Carbon Nanofiber Used for the Synthesis of CoFe-Fe₃N/CNF Electrocatalysts for Rechargeable Zinc-Air Batteries

Posadzy, Marta, et al. Carbon 239 (2025): 120308.

Carbon nanofiber (CNF) serves as a critical conductive scaffold in the synthesis of CoFe-Fe₃N/CNF nanocomposites, which act as highly efficient bifunctional electrocatalysts for oxygen evolution (OER) and oxygen reduction (ORR) reactions in rechargeable zinc-air batteries (ZABs). This study demonstrates a green and optimized hydrothermal synthesis strategy followed by nitridation to integrate bimetallic nitrides with CNFs.
In the synthesis, 0.06 g of CNF was ultrasonicated in water-isopropanol to achieve stable dispersion. Metal nitrate salts-Co(NO₃)₂·6H₂O and Fe(NO₃)₃·9H₂O-along with urea were introduced, followed by hydrothermal treatment at 150 °C for 24 h. After centrifugation, washing, and vacuum drying, the resulting metal oxide/CNF precursor was calcined at 300 °C under N₂ and nitrided at 500 °C in NH₃.
The final CoFe-Fe₃N/CNF catalyst exhibited superior bifunctional catalytic activity, attributed to the synergistic interaction between cobalt and iron species, the presence of a cobalt oxide surface layer, and the optimized CNF content (60 wt%). The CNF network enhances electrical conductivity, supports active site dispersion, and provides mechanical stability during battery operation.
This case highlights the application of carbon nanofiber in the fabrication of advanced electrocatalyst composites, paving the way for scalable production of efficient and cost-effective materials for sustainable energy storage technologies.

Carbon Nanofiber for the Preparation of Biodegradable and Conductive Nanocomposite Electrodes

Sharma, V. K., Chakraborty, G., Narendren, S., & Katiyar, V. (2023). Materials Advances, 4(23), 6294-6303.

In this study, carbon nanofiber (CNF) served as a critical reinforcement material for the development of a biodegradable, flexible, and highly conductive nanocomposite electrode. Surface-modified carbon fibers (mCFs) were synthesized by sequential acid oxidation (HNO₃/H₂SO₄) and functionalization with thionyl chloride, enabling covalent grafting with polyvinyl alcohol (PVA). The resulting PVA/mCF nanocomposite demonstrated exceptional electrical conductivity, with a 10⁶-fold reduction in surface impedance compared to neat polymers.
Various PVA/mCF composites (6-20 wt% CNF) were prepared via probe sonication and reflux grafting, followed by freeze-drying. These nanocomposites were subsequently integrated with electrospun polylactic acid (PLA) nanofiber mats either by direct electrospinning or dip-coating techniques to produce PVA/mCF@PLA-es and PVA/mCF@PLA, respectively. These flexible, nonwoven mats exhibited improved electrical conductivity and mechanical properties, making them promising candidates for bioelectronic, biofuel cell, and flexible device applications.
The study exemplifies the utility of surface-functionalized carbon nanofibers in engineering conductive nanocomposites with biocompatible polymers. The strategic integration of CNFs with PVA and PLA yields sustainable materials with tailored performance for next-generation soft electronic platforms. This work highlights carbon nanofibers as a versatile nanofiller for the preparation of electroconductive and biodegradable electrode materials.
