Engineering 3-D Li-Ion Electrodes with Enhanced Charge Storage Properties Based on Solution-Processed and Sintered Anatase Nanocrystal-Carbon Mesoporous Structures
Bibliographic record
Abstract
Three-dimensional (3-D) monolithic electrodes are an excellent platform for enhancing the electrochemical properties of Li-ion batteries, but fabrication involves complex, difficult to scale-up processing. Current electrode fabrication based on polymeric binder-based pastes of the active material and carbon is expensive and requires volatile toxic organic solvents. Here, aqueous-synthesized anatase (∼6 nm) is used as active material in a green fabrication process employing controlled sintering at 450 °C of an ethanolic paste to engineer mesoporous 3-D structures. This enables construction of self-supporting electrodes endowed with a percolating carbon network with enhanced conductivity that exhibit highly stable cycling performance. As such, the new 3-D electrodes achieve greater capacity (185 vs 145 mAh g –1 at 1C rate) than standard PVDF binder-based electrodes, and serve as a new approach toward easily scalable and sustainable electrode manufacturing applicable to various active materials.

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.
