Synthesis of Polypyrrole-coated NiO/Ni(OH)2 Hybrid Flowers Composite by Pulse Electro-polymerization for supercapacitor with Improved Electrochemical Capacitance
Bibliographic record
Abstract
This work describes a novel strategy to synthesize polypyrrole-coated NiO/α-Ni(OH) 2 hybrid flower with an improved capacitance performance for supercapacitor. Polypyrrole nanoparticles with a size of 80-100 nm were prepared by a pulse electro-polymerization and uniformly embedded into the petal gap of the self-assembled NiO/α-Ni(OH) 2 hybrid flower. Due to the enhancement of the electrical conductivity and the improvement of electrochemical pseudo-capacitance, the as-synthesized polypyrrole-coated NiO/α-Ni(OH) 2 hybrid flower composite showed a high reversible specific capacity of 359 F g -1 at 5 A g -1 in 2 M KOH electrolyte in a potential range of 0 - 0.45 V. Benefiting from the unique electro-polymerization design, the obtained hybrid flower composite demonstrated excellent capacitive performance and cycling stability after 1000 cycles, demonstrating the promising application as a high-performance pseudocapacitive material for supercapacitors.

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.
