How A Battery Works

In class we have been learning how batteries work. Here is a description of how a battery works.

Electrons have a negative charge so they are attracted to the positive end of the battery but there is a electrolyte in their way. The electrons want to go to the Cathode because they are attracted to the positive charge. The only way to get the electrons to the Cathode is when you connect the circuit with a wire and when the electrons pass through the wire they light up the lamp. When the battery runs out of chemicals that create a difference in the electrical charge that means the battery is dead and cannot be used.
