INTERNATIONAL JOURNAL OF IMPACT ENGINEERING, ISSN: 0734-743X, DOI: 10.1016/j.ijimpeng.2021.103915, Vol.155, pp.1039152-1-16, 2021 Streszczenie:
The deformation and failure of a Li-ion pouch battery under a high-velocity impact are studied experimentally and numerically. Ballistic tests were performed with 9 × 19 mm small-caliber projectiles travelling at 360 m/s, using state-of-the-art recording equipment and post-mortem examination under CT scan. The experimental observations are followed by a numerical simulation of the detailed multi-layer battery model. The study provides an insight into mechanisms of the progressive delamination and fracture of subsequent layers. The predicted residual velocity is very close to the measured values, but the impact energy absorption of the battery was found to be relatively low. The presented experimental and numerical analysis may contribute to a design of protection systems, in which rechargeable Li-ion batteries are included. Słowa kluczowe:
