| Description: |
The use of composite materials and lithium-ion batteries (LIB) has expanded across transportation sectors. The most severe failure mechanism for LIBs is Thermal Runaway (TR), i.e. when a battery enters a state of uncontrolled, self-heating ultimately resulting in fire, including ejected material. Most battery-pack enclosure (BPE) design exercises require large-scale TR, vibration or crash testing, which is expensive, time consuming and potentially wasteful in terms of material resources. As such, modelling, which could replace some of this physical testing, would reduce waste and potentially streamline the design process. Therefore, this work first summarises TR experiments completed on lightweight carbon fibre/polyetheretherketone (CF/PEEK) panels, and the resulting strength knock-down using Compression after Thermal Runaway (CaTR) tests. The paper then focusses on the development of Finite Element (FE) based modelling to assess thermal and mechanical damage during and after a LIB TR event which is validated using the aforementioned experiments. Results have shown multi-cell TR induced damage on the composite laminate can potentially reduce its residual compressive strength to around 110 MPa, approximately 20% of its initial strength. FE models accurately predicted the back-surface temperature of the specimens within 10% of the experimental data and the resulting CaTR residual strength within 7%, demonstrating good agreement with the experimental results. |
