Carbonization‐free wood electrode with <scp>MXene</scp>‐reconstructed porous structure for all‐wood eco‐supercapacitors
Bibliographic record
Abstract
Abstract To bypass the conventional high temperature carbonization, MXene with an ultra‐high electrical conductivity and good electrochemical activity is coated on natural wood to make it a free‐standing electrode (TW). TW achieves a high electrical conductivity of 106.4 S m −1 and large capacitance of ~700 mF cm −2 at 0.5 mA cm −2 . Furthermore, to overcome the low space utilization of the oversized vessels in wood which leads to a low energy density, a reconstructing strategy is used on TW to fully use the natural porous structure of wood by filling MXene aerogels in vessels. Compared with TW, the MXene aerogel‐loaded TW shows higher electrical conductivity of 323.6 S m −1 and capacitance of 930 mF cm −2 with remarkably high rate capability of 88.2% (0.5–10 mA cm −2 ). Additionally, an all‐wood eco‐supercapacitor is fabricated, and achieves a high energy density of 23 μW h cm −2 at 577 μW cm −2 . image

Full frame distilled prediction
Teacher imitationNot 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.
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 teacher head, not a consensus.
