The ionic formula for Lithium Oxide is $L i_{2} O$ $Li_2O$ .

Lithium is an Alkali Metal in the first column of the periodic table. This means that lithium has 1 valence electron it readily gives away in order to seek the stability of the octet. This makes lithium a $L i^{+ 1}$ $Li^(+1)$ cation.?

Oxygen is in the 16th column or $p^{4}$ $p^4$ group.
Oxygen has 6 valence electrons. It needs two electrons to make it stable at 8 electrons in its valence shells. This makes oxygen a $O^{- 2}$ $O^(-2)$ anion.

Ionic bonds form when the charges between the metal cation and non-metal anion are equal and opposite. This means that two $L i^{+ 2}$ $Li^(+2)$ cations will balance with one $O^{- 2}$ $O^(-2)$ anions.

This makes the formula for lithium oxide $L i_{2} O$ $Li_2O$

I hope this is helpful.
