If Electricity Can’t Be Stored, Then What’s In A Battery?
A battery is an electrical energy source consisting of one or more cells. The cell has two terminals, called the anode (-) and cathode (+), which are made of various chemicals, often metals.
There is an electrolyte between the connections, which can be liquid, pasty, or solid, and conducts ions. The electrolyte can also contain soluble salts or acids.
The separator prevents contact between the anode and cathode.
When a device is connected to a battery, chemical reactions occur at its terminals, causing a flow of electrons and converting chemical energy into electrical energy.
The battery does not store electrical energy, but rather chemical energy, which is converted into electrical energy when required.
