nice article, but I have a problem with the notion that if a lithium-ion battery pack starts smoking that a bottle of water is going to help.  if that’s the case then why does the battery hazard training I’ve been through specifically say that the only way to deal with a runaway li-ion pack (as in, don’t want to watch the pretty light show and see the flames and smoke as the hot gases resulting from the dissociated electrolyte combust with oxygen in the air) is to make sure it’s on a surface that can take the potentially 3000F temperatures and dump a five gallon pail of sand on it.  then open the windows to let the fumes out of the building and wait for the thermal event to cool off.  I would be more afraid of the water I just dumped on the now melted plastic case of the pack shorting out more of the cells causing an even bigger thermal event.  probably better “thermal runaway event protection” would be a high heat tolerant sleeve made out of welders cloth.
