摘要

锂离子电池是一种优秀的储能设备，被广泛应用于多个领域。然而，电池燃烧引发的事故是一个亟待解决的问题。本文研究了一种防止电池燃烧的新方法。对不同充电阶段（SOC）电池燃烧情况的研究表明，SOC 越高的电池燃烧越剧烈，电池中喷出的物质粉末也越多。高温粉末是电池燃烧的点火源。可以使用阻火器来防止电池燃烧。如果粉末被阻挡，就可以防止燃烧。研究发现，当层数（n）= 10、网目数（m）= 60 和 n = 5、m = 80 时，对于 SOC 等于和低于 80 % 的电池，阻燃效果是成功的；对于 SOC 为 100 % 的电池，当 n = 10、m = 60 时，阻燃效果是成功的。随着金属丝网的目数和层数增加，阻燃效果更好。不过，金属丝网更容易从阻火器中弹出，因为它们可以被粉末完全阻挡。

Lithium-ion battery combustion with different state of charge and combustion prevention based on flame arrester

Lithium-ion battery is an excellent energy storage device and used in many fields. However, accident of battery caused by combustion is an urgent issue to be solved. A new method to prevent battery combustion is studied in this work. The study about the combustion of batteries with different stage of charge (SOC) indicate that the combustion is more violent for battery with higher SOC, and more material powders are ejected out of the battery. The high-temperature powder is the ignition source of battery combustion. Flame arrester can be used to prevent battery combustion. The combustion can be prevented if the powders are blocked. It is found that the flame retardant effect is successful for battery with SOC equal to and lower than 80 %, when the layer (n) = 10, mesh number (m) = 60 and n = 5, m = 80, For battery with 100 % SOC, the flame retardant effect is successful when n = 10, m = 60. With the increasing mesh number and layer for metal wire mesh, the flame retardant effect is better. However, the metal wire mesh is easier to be ejected out of the flame arrester as they can be fully blocked by the powders.

期刊介绍： Thermal Science and Engineering Progress (TSEP) publishes original, high-quality research articles that span activities ranging from fundamental scientific research and discussion of the more controversial thermodynamic theories, to developments in thermal engineering that are in many instances examples of the way scientists and engineers are addressing the challenges facing a growing population – smart cities and global warming – maximising thermodynamic efficiencies and minimising all heat losses. It is intended that these will be of current relevance and interest to industry, academia and other practitioners. It is evident that many specialised journals in thermal and, to some extent, in fluid disciplines tend to focus on topics that can be classified as fundamental in nature, or are ‘applied’ and near-market. Thermal Science and Engineering Progress will bridge the gap between these two areas, allowing authors to make an easy choice, should they or a journal editor feel that their papers are ‘out of scope’ when considering other journals. The range of topics covered by Thermal Science and Engineering Progress addresses the rapid rate of development being made in thermal transfer processes as they affect traditional fields, and important growth in the topical research areas of aerospace, thermal biological and medical systems, electronics and nano-technologies, renewable energy systems, food production (including agriculture), and the need to minimise man-made thermal impacts on climate change. Review articles on appropriate topics for TSEP are encouraged, although until TSEP is fully established, these will be limited in number. Before submitting such articles, please contact one of the Editors, or a member of the Editorial Advisory Board with an outline of your proposal and your expertise in the area of your review.
