Abstract

fetched live from OpenAlex

Abstract Lithium (Li) metal anodes are considered an ideal anode for the next‐generation Li batteries with high energy density. However, some intrinsic problems, such as Li dendrite growth and tremendous volume change, inhibit their practical applications. Here, an unstacked microstructure is tailored by planting an N‐doped carbon nanotube (CNT) forest on the surface of biomass‐derived large‐aspect‐ratio N‐doped carbon sheets (CSs) (CS‐CNT), which can effectively overcome the easy aggregation properties of CSs. As the host material for Li metal anode, the N‐doping and unstacked natures of CS‐CNT offer sufficient Li nucleation sites, large surface area, and space for smooth and uniform Li deposition, effectively preventing the formation of dendritic Li. As a result, the cell with this electrode can keep high and stable Coulombic efficiency of 98.8% for over 2000 h, superior to the pure CSs and Cu foil electrodes. Additionally, the symmetric cell exhibits significantly enhanced cycle life up to 1500 h as well as lowered hysteresis. The present study sheds light on the design of unstacked porous carbon materials and offers an opportunity to develop high efficiency Li metal anode.

Not 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.
