Direct Semiconductor Laser Writing of Few‐Layer Graphene Polyhedra Networks for Flexible Solid‐State Supercapacitor
Bibliographic record
Abstract
Abstract Here, a simple one‐step fabrication methodology is presented for continuous heteroatoms‐doped carbon polyhedra networks via direct semiconductor laser writing on polyimide sheets. It is found that these nanosized polyhedra are nonporous solids and comprised of few‐layer graphene. By the adoption of lithium containing polymer gel electrolyte, flexible solid‐state supercapacitors are designed and assembled in planar and interdigitated configuration with the irradiated plastic sheets as electrodes. When compared to their counterparts with the acid gel electrolyte, they exhibit high areal specific capacitance up to 34.7 mF cm−2 (vs ≈8 mF cm−2) at the current density of 0.1 mA cm−2. This substantial enhancement is considered to be due to the combination of Faradaic intercalation and non‐Faradaic absorption of the Li‐ions at the carbon polyhedra membrane electrodes. With the improvement of energy density, the complex of supercapacitor device is capable of lighting the liquid crystal display of a commercial hygrometer for ≈1 min.

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.
