Although the UN classifies lithium batteries as dangerous goods, current UN numbers for lithium batteries do not indicate what level of hazard each individual shipment may pose. Lithium batteries can exhibit varied temperature rise and propagation characteristics when heated to thermal runaway. Therefore, This study was conducted to characterize the propagation of cylindrical cells and pouch cells at various states-of-charge (SoCs) to determine or verify key test factors that should be considered for development of a lithium battery propagation test.
This work explores propagation mitigation in packs of lithium ion pouch cells commonly used in large electric vehicles. Sub-assemblies were constructe...
This interim report for single-cell thermal runaway initiator activities performed at Sandia National Laboratories looks at novel initiation methods a...
