The reason for recent battery issues have been primarily because manufacturers are pushing for tighter tolerances to make more energy dense batteries and smaller safety spaces in battery compartments. At the point they build in a fire extinguisher, why not go back to roomier batteries and compartments? Does this built in fire extinguisher impact the battery size and tolerances or does it replace existing materials? It was disappointing to not see that covered in the article.

So it's more of a demonstration that the flame retardant can be placed in a battery separated from the electrolyte by a heat activated membrane than it is a fully engineered end user battery.
