Mitigation Strategy: Packaging
The packaging of lithium batteries my be used to improve safety in the event of thermal runaway. Safe packaging may be able to slow or possibly eliminate battery-to-battery thermal runaway propagation.
Packaging that has been shown to be effective includes boxes with sufficient spacing or insulation between batteries to prevent thermal runaway propagation, and packages that have a built-in mechanism to absorb heat such as liquid pouches or phase-change materials. The FAA report "Passive Protection of Lithium Battery Shipments" provides technical information related to battery packaging.
SAE is in the process of developing a packaging standard (G27 Chamber) that is intended to qualify whether a package will be safe in the event of thermal runaway. It is yet-to-be-seen how effective and practical the standard will be. Information on the status of the G27 group can be found here: SAE G27 Status
