That's the chemical formula of lithium carbonate.

Explanation:

Lithium carbonate is an ionic compound formed when a lithium cation, #"Li"^(+)#, bonds ionically to a carbonate anion, #"CO"_3^(2-)#.

Notice that you need two lithium +1 cations to balance the negative 2- charge of the carbonate anion.

This is shown by the #2# subscript that lithium has in the formula unit #"Li"_2"CO"_3#.
