Graphene-Wrapped ZnMn<sub>2</sub>O<sub>4</sub> Nanoparticles with Enhanced Performance as Lithium-Ion Battery Anode Materials
Bibliographic record
Abstract
ZnMn 2 O 4 nanoparticles (NPs) wrapped by reduced graphene oxide (rGO) were fabricated via a two-step solvothermal method and used as an anode material for lithium-ion batteries (LIBs). Compared to pure ZnMn 2 O 4 , the ZnMn 2 O 4 NPs/rGO composites deliver higher capacities of 1230 mAh g −1 and 578 mAh g −1 after 200 cycles at a current density of 100 mA g −1 and 500 mA g −1 , respectively. The enhanced electrochemical performance of ZnMn 2 O 4 NPs/rGO composites is mainly attributed to a distinctive structure (ZnMn 2 O 4 NPs surrounded by flexible rGO), which can promote the diffusion of Li + , accelerate the transport of electrons and buffer volume expansion during the Li + insertion/extraction process. Furthermore, the rGO sheets can effectively prevent the agglomeration of ZnMn 2 O 4 NPs, thus, improving structural stability of the composites. The excellent electrochemical performance indicates that such ZnMn 2 O 4 NPs/rGO composite structure has a great potential for high-performance LIBs.

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.
