How Do Batteries Work?
Electricity is the flow of electrons through a wire, that is called a circuit. Batteries have three parts to them, an anode, a cathode, and an electrolyte. The cathode and the anode are hooked up to an electrical circuit. The chemical reaction that is happening causes the electrons to build up at the anode. When the circuit is closed the electrons will be able to get to the cathode. When the electrochemical process change the chemicals in the anode and cathode it makes them stop supplying electrons. So that’s why there's a limited amount of power in a battery. When you recharge a battery you change the direction of the flow of electrons using the other power source just like solar panels. You can sit a battery on a shelf for a year and it will still have power. This is because unless the electrons are flowing fom the negative to the positive terminal, the chemical reaction does not take place or it doesn't happen. Batteries convert chemical energy into electricity. When a battery is connected to an electric circuit, a chemical reaction takes place causing the ions to flow through it one way with electrons flowing the other way. There are alot of different types of batteries, but there are two main types: disposable and rechargeable. Primary cells make up the power in disposable batteries, and secondary cells power the rechargeable batteries. What I learned is that when you charge your cellphone you are really just running the battery in reverse.
