Summary: CNFs/V2O5/PEDOT composite electrode shows significant enhancement in electrochemical performance in lithium-ion batteries, with initial discharge capacity of 520 mAh/g, nearly doubling that of CNFs/V2O5 electrode. However, the electrode exhibits rapid degradation due to electrode pulverization and unstable SEI formation. By applying cut-off voltages of 1.0 to 2.5 V, the cycling performance improves with enhanced charge transfer resistance, indicating that PEDOT can serve as a protective layer for the electrodes.
