Why does the structure of lithium oxide allow it to conduct electricity under certain conditions?

Lithium oxide has the formula Li₂O. It has an ionic structure as it is formed from a metal and a non-metal. It has lithium ions with a +1 charge, as lithium is found in Group 1 of the periodic table, and oxygen ions with a charge of -2 as it is a Group 6 element. Therefore, there are 2 lithium ions for every oxygen ion, and they are held together by electrostatic forces which is the attraction between oppositely charged ions. They are held together in a lattice.Li₂O is able to conduct electricity when molten or dissolved in water. This is because the electrostatic forces are weakened, so the ions are no longer held in a lattice. The ions are therefore free to move throughout the structure and carry the charge.
