Abstract

fetched live from OpenAlex

The electrospun nanofiber membrane had excellent performance when used as separator of Li-ion battery.Its applications were limited due to the low cohesive force between single nanofibers and the low strength of the electrospun membrane. The PAN-PVDF electrospun membrane was prepared by blended electrospinning with thermostable phase PAN and low melting temperature phase PVDF. PVDF was melted partially to form point bonding after proper thermal calendering process and its relevant properties were measured. The results show that the strength of the modified membrane is almost 10 times higher than that of as-spun electrospun membrane. The improvements in electrochemical properties of the electrospun samples were also observed in this study such as,(1)ionic conductivity at room temperature was 1.32×10-3 S/cm;(2) electrochemical stability potential was 5.24 V;(3)interface impedance between the membrane andthe electrodes was 45 Ω; and(4) the initial discharge capacity was152 m Ah/g under 0.2 C ratio. Therefore, the comprehensive properties of the modified membrane were superior to that of CELGARD 2400.

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
