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 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.
