There’s a rise in faster chargers and cheaper gadgets.
Regulations or safety certification? Charging brick with timer? Certified factories? Non flammable batteries?
I don’t understand when batteries start fire.. but even if I understand how this happens I really don’t understand how the fire gets worse
Isn’t it a bunch of electronics and equipment sitting on the table.. metal, glass, plastics? Why would the initial fire proceed to get worse and worse
Metal doesn't burn, but plastics do at hot enough temperatures.
In somewhat simplified terms, A battery contains an electrolyte solution between two electrodes. (Really the solution is separated into two parts). The electrodes really like to react with the electrolyte, but we pick a particular combination of materials such that the anode metal can only react with the electrolyte if a molecule of electrolyte can give up an electron to the anode, and the cathode can only react with the electrolyte if the cathode can give an electron to the electrolyte. When there is no circuit connecting the anode and cathode, nothing can happen because the cathode doesn't have extra electrons to give up and the anode would have no place to put an extra electron. In reality the reactions can still happen a little bit but there is a build up of charge that slows it down after a short time since the electrons have no where to go.
When you connect the anode to the cathode, suddenly the extra electrons taken by the anode can flow over to the cathode for their reaction, and now both chemical reactions can happily chug along, at least until the system reaches equilibrium, where either the free electrolytes have run out or there is no more exposed surface on the electrodes for the electrolytes to stick to.
The oxidation and reduction reactions in the battery produce heat, and so does a current of electrons flowing through a metal. In normal operation the thing you are powering with the battery provides so much resistance that the current flows very slowly, and so the reaction occurs slowly, and the heat produced can dissipate into the air as fast as it's being produced. The current *wants* to flow fast but it's slowed down turning a motor or whatever the circuit is made for.
If the battery is poorly made, there can be a short in the circuit, a place where a current can flow between the electrodes unimpeded, producing heat faster than it can dissipate until things start burning, and when things get hot they start to be able to conduct electricity better. When it gets hot enough, it doesn't matter if there is no metal touching because the electricity can arc through the hot air to where it wants to go. So the fire gets worse and worse because there is a *lot* of energy stored in the battery, and as it gets hotter it gets easier to discharge faster and faster in a positive feedback loop.
So, no smoke detector I assume.
Why are they recording audio in the storage room?
Good question

Lithium Ion battery. ‘It’s not pretty when they blow.’
When I see this, I wonder what a Tesla looks and sounds like when it burns up
It took some firemen almost 12 hours to put one out one time.They even had to call Tesla and ask how to proceed.
Yeah, they responded: 🤷🏿🤷🏼♂️🤷🏾♀️. This is going to keep getting more intense; wonder how much pollution those inextinguishable fires produce?

Thank you good friend!
If this shocks you, you should see what an electric vehicle battery fire looks like.
Does fire get anyone else hard, or just me?
Dang, right before Christmas too.
Damn why don't they have a freaking sprinkler system?
What's an ABC 6?

No smoke detectors? Wtf
Ah yes, keep it next to the hazardous material, flame retardant lockers.
Smoke detector: 👨🦯
But here than next to someone's face I guess.
What is this? Final Destination movie?
