how do we get electricity/energy out of a battery? A battery is just made of metal and liquid right?
In: Physics
The composition of a battery can hold electrical energy charge. Therefore, if you insert two pieces of metal on a lemon, you will get some electricity.
The same works for a lithium ion battery. It is a dry cell battery, meaning that it has no liquids inside. There is a long strip of lithium (it is rolled up inside the battery. That is where electricity is stored, and it gets the electricity by attaching metal conductors on each end.
