This is in China.

So what's wrong with these batteries besides being made in China? What would make a battery just explode out of nowhere? I don't have any answers, that's why I'm asking.

It’s a chemical chain reaction…once it’s starts it’s never going out until the chemical process is over. What trigger it, IDK.

Same reason airlines don't want you to put Lithium ion batteries in your checked luggage.

Quote:What causes battery fires
Typically, a battery fire starts in a single cell inside a larger battery pack. There are three main reasons for a battery to ignite: mechanical harm, such as crushing or penetration when vehicles collide; electrical harm from an external or internal short circuit; or overheating.

Battery short circuits may be caused by faulty external handling or unwanted chemical reactions within the battery cell. When lithium-ion batteries are charged too quickly, chemical reactions can produce very sharp lithium needles called dendrites on the battery’s anode – the electrode with a negative charge. Eventually, they penetrate the separator and reach the other electrode, short-circuiting the battery internally.

Such short circuits heat the battery cell to over 212 F (100 C). The battery’s temperature rises slowly at first and then all at once, spiking to its peak temperature in about one second.

Another factor that makes lithium-ion battery fires challenging to handle is oxygen generation. When the metal oxides in a battery’s cathode, or positively charged electrode, are heated, they decompose and release oxygen gas. Fires need oxygen to burn, so a battery that can create oxygen can sustain a fire.

Because of the electrolyte’s nature, a 20% increase in a lithium-ion battery’s temperature causes some unwanted chemical reactions to occur much faster, which releases excessive heat. This excess heat increases the battery temperature, which in turn speeds up the reactions. The increased battery temperature increases the reaction rate, creating a process called thermal runaway. When this happens, the temperature in a battery can rise from 212 F (100 C) to 1,800 F (1000 C) in a second. https://www.youtube.com/embed/kHTlVmBbnP...nt&start=0 In thermal runaway, a lithium-ion battery enters an uncontrollable, self-heating state that can lead to fire or explosion.
