How what kind of short do you refer ?1) Short circuits that provide an ignition source (a spark) and heat
2) Aqueous electrolyte that decomposes to oxygen
3) Flammable materials (plastic separator, graphite anode)
... phones use lithium ion battery packs for their power, and it just so happens that the liquid swimming around inside most lithium ion batteries is highly flammable.
If the battery short-circuits -- say, by puncturing the incredibly thin sheet of plastic separating the positive and negative sides of the battery -- the puncture point becomes the path of least resistance for electricity to flow.
It heats up the (flammable!) liquid electrolyte at that spot. And if the liquid heats up quickly enough, the battery can explode.
Shorts caused by dendrite growth (caused by fast charging) material defects or mechanical damage.How what kind of short do you refer ?
Yes.Do they use aqueous electrolyte ?
I had an impression they use methylcarbonateShorts caused by dendrite growth (caused by fast charging) material defects or mechanical damage.
Yes.
Yes, they use materials like ethylene carbonate, dimethyl carboate and diethyl carbonate. All those contain oxygen. Note that this is just the solution that the lithium salts are dissolved in; the salts are the active material.I had an impression they use methylcarbonate
I am not sure water is really necessary . In the past as I worked with polyglycols some if them dissolve chloride salts so I would not be surprising if the salts have to be solubilised in water . I assume the main solvent is methyl carbonate, but welcome to contradict me if you have the real information . I am willing to learn .Yes, they use materials like ethylene carbonate, dimethyl carboate and diethyl carbonate. All those contain oxygen.

It's not. The organic solvents above do not contain water, for example. Lithium ion batteries are made with both. Modern batteries generally use organic solvents like ethylene carbonate.I am not sure water is really necessary.

Refer to posts 2 and 4. If you are having problems with the English language there is a section for that.
Overall cause? Trying to cram too much energy, too quickly, into a limited capacity storage device . H-m-m-m-m-m- . . . . reminds me of another similar circumstance that happened 13.5 by (or so) ago . . . . . called "Big Bang! tee hee)What causes fire in the battery ?
Why are you mentioning good for sun glassesLithium is the power source and has many different isotopes. Most are radioactive. So while some materials are the source for ignition the cause is the lithium itself.
I recommend adding iridium to key points if you are attempting to make your own battery. Good for sunglasses
