Abstract

fetched live from OpenAlex

Interest in developing electrodes for flexible supercapacitors for wearable and portable electronic devices is rising. 2D interfacial heterostructures have garnered significant attention due to their robust structural integrity and excellent electrochemical compatibility. This work demonstrates an innovative and novel electrode combining Ti 3 CNT x and Nitrogen-doped electrochemically exfoliated graphene (N-EEG) for flexible supercapacitors, effectively mitigating self-restacking and enabling enhanced diffusion of electrolyte ions to electroactive sites. The maximum volumetric capacitance of 331 F cm –3 (at a current density of 1 mA cm –2 ) was achieved with an optimized ratio of N-EEG to Ti 3 CNT x, surpassing some reported graphene- or MXene-based supercapacitors. This hybrid electrode retained 93% capacitance after 10 000 charge–discharge cycles, highlighting its durability. A symmetric supercapacitor exhibited a volumetric capacitance of 155 F cm –3 and good stability with ∼100% retention after 10 000 cycles. Such a remarkable performance underscores the potential of the N-EEG@Ti 3 CNT x nanocomposite for the development of supercapacitors.

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.
