Development of cost‑effective electrode materials with high capacity and stability is crucial for advanced energy storage. Carbon nanofibers derived from biomass and polymers combine porous morphology with good conductivity, making them promising candidates.

Purpose – to analyze structural, morphological, and electrochemical properties of carbon nanofibers produced by electrospinning a sawdust/PAN (30:70) composite and to assess the effect of carbonization temperature.

The sample carbonized at 800 °C (CNF‑800) showed the best combination of structural stability and electrochemical performance. In the first cycle at a current density of 100 mA/g, CNF‑800 exhibited an initial specific capacity of 798 mAh/g. During long‑term cycling (500 cycles) at 500 mA/g all samples remained operational; CNF‑800 retained a capacity of 300–400 mAh/g. Increasing the carbonization temperature altered porosity and conductivity, which affected the capacitance characteristics.

These biomass‑derived carbon nanofibers are promising for electrode applications in energy storage devices, offering a route to lower‑cost and more sustainable materials.
