Abstract

fetched live from OpenAlex

Abstract Asymmetric lithium‐ion supercapacitors have been obtaining great attention, owing to their significantly increased energy density. However, transition‐metal‐oxide‐based electrode materials with poor conductivity and sluggish electrode kinetics often sacrifice power performance and cycling stability. Herein, we report the in situ growth of V 2 O 5 nanorods on highly conductive graphene sheets as anode materials with high specific capacitance and excellent rate capability, which is mainly attributed to the intimate contact between the nanorods and graphene sheets. The asymmetric supercapacitor based on graphene/V 2 O 5 composites and activated carbon is fabricated and evaluated, where a high energy density of approximately 50 Wh kg −1 can be achieved at a power density of 136.4 W kg −1 , as well as long cycling stability. This work provides an effective and efficient method for the fabrication of high‐performance asymmetric supercapacitors.

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.
