High-purity few-layer graphene from plasma pyrolysis of methane as conductive additive for LiFePO4 lithium ion battery
Bibliographic record
Abstract
Graphene is one of the most attractive materials because of its outstanding properties. Here we report a straightforward and environmentally friendly process, in which the few-layer graphene is continuously prepared in gas phase by one-step pyrolysis of methane by alternative-current arc plasma under substrate free and atmospheric conditions. The graphene is generated in high purity with the yield of more than 2 g/h. No further operations such as centrifugation, purification, sonication, and drying are needed. The synthesized graphene powder mainly consists of 1–3 layered flakes. The electrochemical performance of the graphene as the cathode conductive filler for LiFePO4 lithium ion batteries is investigated. The most effective electron transporting network in lithium ion batteries is obtained under 2% of graphene, together with 1% of carbon black. Moreover, the addition of graphene increases the specific capacity of the cathode and shows a good rate performance.

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.
