Dual Active Site of the Azo and Carbonyl-Modified Covalent Organic Framework for High-Performance Li Storage
Bibliographic record
Abstract
Organic electrode materials play a crucial role in environmentally friendly and sustainable lithium-ion batteries (LIBs) due to their abundance, high theoretical capacity, inexpensiveness, and recyclability. However, critical issues such as fewer redox-active sites and poor structural stability limit their extensive application in LIBs. Herein, a unique covalent organic framework (Tp-Azo-COF) with a dual active site of N═N and C═O is designed and successfully applied as the anode material for LIBs. Benefiting from its abundance of active sites, large conjugate structure, large surface area, and accessible Li + transport channels, the Tp-Azo-COF anode materials present high electrochemical kinetics and structural stability. The assembled LIBs deliver a specific capability of 305.97 mAh g –1 at a current density of 1000 mA g –1 after 3000 cycles. This work may inspire avenues for the development of advanced organic materials of inexpensive, sustainable, and durable rechargeable batteries.

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.
