What makes one battery rechargeable and another not?
In: 40
The chemicals inside it and the reactions that take place.
A battery runs on what’s called a galvanic cell; it converts chemical energy into electrical energy. This reaction is favourable or “spontaneous” as the chemicals want to react this way to get rid of some energy they have stored in them.
When you recharge your phone the cell flips to becoming an electrolytic cell. These favourable reactions are now being forced to undo themselves, giving the chemicals more energy, which they don’t want(so the reaction is now unfavourable and forced) – but they can then get rid of the energy again by powering your device.
In a non-rechargeable battery it is very difficult or impossible to make the reverse reaction happen.
