All-in- One Graphene-Based Composite Fiber Supercapacitor
Bibliographic record
Abstract
Graphene fibers (GF) have attracted great interest in wearable electronics applications due to their excellent mechanical flexibility and superior electrical conductivity. Herein, a graphene/MnO 2 composite hybrid supercapacitor fiber device has been devised. The unique design of this device overcomes the inconvenience and short circuit risk of conventional designs. The backbone of the device consists of GF that not only provides a durable scaffold for the entire device, but also ensures fast electron transfer during charge-discharge. The introduction of a MnO 2 film with abundant active sites enhanced the pseudocapacitance dramatically, compared to pristine GF. The entire device exhibits outstanding mechanical strength as well as good electrocapacitive performance with a volumetric capacitance of 29.6 F cm-3 at 2 mv s-1 . The capacitance of the device didn’t fade at all under bending testing from 0° to 150°, while the capacitance retention was kept 93% after 1000 cycles. These unique features make this device a promising candidate for applications in wearable fabric supercapacitors.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
