Charge Storage Mechanism of Binderless Nanocomposite Electrodes Formed by Dispersion of CNTs and Carbon Aerogels
Bibliographic record
Abstract
The carbon aerogel (CAG)-multiwalled carbon nanotubes (MWNTs) nanocomposite binderless electrodes and their electrochemical performances in and KOH were investigated. Additionally investigated was their long life. We measured the highest capacitances with an optimum CAG-MWNT composite containing of MWNT displaying a specific capacitance of in vs in KOH. The highest capacitance was obtained with the CAG- MWNT because this sample displayed the highest content of oxygen, and the highest ultramicropore volume that can accommodate electrolyte ions ( in KOH and in ). The capacitance of these materials when subjected to several thousands of galvanostatic charge-discharge experiments revealed that the samples showed a fairly stable behavior in KOH electrolyte, whereas in electrolyte only the composite containing the highest amount of MWNTs (i.e., ) was stable. The other samples displayed a dramatic enhancement in the capacitance during the first few thousands of cycles and then dropped to very low values. This observed phenomenon was ascribed to the swelling and attack of the internal carbon atoms in a concentrated acidic medium.

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.
