Abstract

fetched live from OpenAlex

Abstract In recent years, the frequency of incidents related to the safety of electric vehicles (EVs) due to lithium‐ion batteries has seen a troubling uptick, leading to a heightened focus on the safety of lithium‐ion batteries (LIBs) as a critical area of research. After thorough analysis, this study contends that the root cause of the majority of safety incidents involving LIBs in the field is predominantly linked to reliability issues within the battery products themselves. This argument offers a more targeted perspective than a broad discussion on the safety concerns of LIBs. Reliability, in this context, is defined as the likelihood that a product will execute its intended function without error over a defined period and under specific conditions. The paper delineates the reasons why current safety testing standards are unable to entirely prevent LIB safety incidents, scrutinizes the multifaceted causes and testing methodologies associated with LIB unpredictive thermal runaways from reliability perspective, and aims to reduce the probability of battery field failure and electric vehicle fire incidents, with an emphasis on mtigating unpredictive fire accidents. This study advocates for a more aggressive research effort into the reliability of LIBs, parallel to the vigorous advancement of safety technologies for these batteries.

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.
