Abstract
Lithium-ion batteries have seen widespread use, bringing the issue of thermal runaway into sharp focus. Thermal runaway can be diagnosed by the characteristic gases produced (CO2, H2, CO, CH4, C2H4, C2H6). Black phosphorus (BP) with corrugated plane was utilized as the base material, enhancing its chemical activity with transition metals (Au, Ag, Pt, Pd). The four transition metal-enhanced BPs can selectively adsorb CO and C2H4 with different response characteristics, which can be used to identify CO and C2H4. This study provides theoretical guidance for the engineering application of transition metal-enhanced BP in monitoring thermal runaway gases in lithium-ion batteries.
锂离子电池的广泛使用使热失控问题成为焦点。热失控可通过产生的特征气体（CO2、H2、CO、CH4、C2H4、C2H6）来诊断。以波纹面黑磷（BP）为基材，用过渡金属（金、银、铂、钯）增强其化学活性。四种过渡金属增强的黑磷可选择性地吸附 CO 和 C2H4，并具有不同的响应特性，可用于识别 CO 和 C2H4。该研究为过渡金属增强 BP 在锂离子电池热失控气体监测中的工程应用提供了理论指导。
期刊介绍：
Chemical Physics Letters has an open access mirror journal, Chemical Physics Letters: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review.
Chemical Physics Letters publishes brief reports on molecules, interfaces, condensed phases, nanomaterials and nanostructures, polymers, biomolecular systems, and energy conversion and storage.
Criteria for publication are quality, urgency and impact. Further, experimental results reported in the journal have direct relevance for theory, and theoretical developments or non-routine computations relate directly to experiment. Manuscripts must satisfy these criteria and should not be minor extensions of previous work.
