to me lithium ion batteries in phones, and how they overheat
In: Technology
In any realistic medium, electrons moving through it will have some resistance. Resistance causes energy lost to the environment by way of heat, light, and sometimes sound. Light bulbs are a great example of electricity causing light to be produced. Space heaters are the go to for heat. The more resistance, the more energy loss.
Li Ion batteries are like any electrical component and will have that resistance with use. This will build up heat. They normally act like a little electric cliff. All the electrons are put on top of the cliff and bit by bit they fall down doing the electrical work that you want them to do, powering your device. The neat part about Li Batteries is that it’s not a particularly steep cliff, so with some effort and force, you can shove those electrons back on top. When you do this, the battery will output a lot of heat since it’s not efficient. About 12% of the energy put in is lost as heat. Batteries are built to discharge energy slowly, so building up energy in them is going to have losses.
