Accelerating charging and elevating capacity of TiO <sub>2</sub> by interface space charge storage
Bibliographic record
Abstract
Abstract Titanium dioxide (TiO 2 ) is an extremely promising anode material for lithium‐ion batteries due to its low cost, minimal volume change, and extended cycle life. However, its electrochemical performance is severely hindered by inherent issues such as poor ionic and electronic conductivity. Here, we design a dual‐phase conductor Co@TiO 2 , which contributes a synergistic storage mode consisting of a Li‐accepting and an electron‐accepting phase. In situ magnetic characterization and experimental results reveal the space charge storage mechanism in addition to traditional insertion mechanisms. Based on these mechanisms, the specific capacity and rate performance of the Co@TiO 2 electrode have been greatly enhanced. Under a current density of 200 mA·g −1 , the specific capacity of Co@TiO 2 reaches 397.2 mAh·g −1 . Upon increasing the current density to 10 A·g −1 , the electrode still maintains a capacity of 83.1 mAh·g −1 after 900 cycles. This result offers a fresh perspective on the structural design of new anode materials to achieve high energy density.

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.
