M etal oxide a lithium battery also uses  electrolyte  and  graphite . Graphite has a  layered structure . This layers are loosely bounded in order to easily store the lithium ions in them. The electrolyte, which is located between graphite and metal oxide, acts as a guard which allows only lithium ions through ( no electrons are allowed to pass). If we connect a  power source  between the two metals, the  positive side  will attract and remove electrons from the lithium atoms of the metal oxide. This electrons will flow through the external circuit, since they can not flow through the electrolyte, and reach the graphite layer. In the mean time the positively charged lithium ions will be attracted from the  negative terminal  and they will flow through the electrolyte reaching the graphite space. When the lithium ions reach the graphite sheet, the battery is  fully charged . In this way we have achieved the first objective; the lithium ions and electrons to be detached from the metal o
