Electrochemistry of InSb as a Li Insertion Host: Problems and Prospects
Bibliographic record
Abstract
Ballmilling of In and Sb has been used to produce InSb for use in electrochemical and in situ X-ray diffraction studies (XRD) of ethylene carbonate:diethyl carbonate/InSb cells. The cell capacity decays rapidly when cycled between 0 and 1.3 V, while the capacity reduction is less pronounced when cycling is restricted to the 0.65-1.4 V range. In situ XRD studies reveal that and In are formed during the first plateau (above 0.65 V), according to the reaction The indium product subsequently reacts with Li forming the phases InLi and in sequence. When cells are cycled above 0.6 V ( i.e. , in the absence of formation) capacity retention improves significantly, remaining relatively constant near 250 mAh/g. Detailed in situ XRD studies of these cells suggest that 0.27 Li atoms per InSb may be intercalated during a sharp drop in the cell potential, according to the reaction This intercalation accounts for only a small (about 30 mAh/g) fraction of the overall capacity of 680 mAh/g. Consequently, it appears that the reactivity of In and Sb with Li, not the structure type, determines the reaction path. Therefore, InSb is not an attractive intercalation host for Li, in contrast to the claims made in the literature. © 2001 The Electrochemical Society. All rights reserved.

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.
