Abstract

fetched live from OpenAlex

Abstract Nanostructured V 2 O 5 thin films have been prepared by means of cathodic deposition from an aqueous solution made from V 2 O 5 and H 2 O 2 directly on fluorine‐doped tin oxide coated (FTO) glasses followed by annealing at 500°C in air, and studied as film electrodes for lithium ion batteries. XPS results show that the as‐deposited films contained 15% V 4+ , however after annealing all the vanadium is oxidized to V 5+ . The crystallinity, surface morphology, and microstructures of the films have been investigated by means of XRD, SEM, and AFM. The V 2 O 5 thin film electrodes show excellent electrochemical properties as cathodes for lithium ion intercalation: a high initial discharge capacity of 402 mA h g −1 and 240 mA h g −1 is retained after over 200 cycles with a discharging rate of 200 mA g −1 (1.3 C). The specific energy density is calculated as 900 W h kg −1 for the 1 st cycle and 723 W h kg −1 for the 180 th cycle when the films are tested at 200 mA g −1 (1.3 C). When discharge/charge is carried out at a high current density of 10.5 A g −1 (70 C), the thin film electrodes retain a good discharge capacity of 120 mA h g −1 , and the specific power density is over 28 kW kg −1 .

Full frame distilled prediction

Teacher imitation

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.
