How Do Lithium-Ion Batteries Work?
Season 3 Episode 38 | 3m 46s
We explain the chemistry of lithium-ion batteries, why they occasionally explode.
There's a lot of science behind those lithium ion-batteries in the latest generation of phones. But like most new generations of smartphones, its battery has pretty much stayed the same over the years. Short of carrying an external battery all the time, is there any way to extend the life of your smartphone battery? How does heat affect your battery? What causes them to become unstable?
