The polyatomic cation for lithium nitrate is Li+. This cation is derived from the element Lithium with a positive charge in the compound lithium nitrate.
Assuming that questioner intended to complete the question with "carbonate, or nitrate" instead of the nonexistent "carbonatenitrate": Carbonate and nitrate ions are both polyatomic; lithium and calcium ions are both monatomic.
The common name for lithium nitrate is simply lithium nitrate.
The polyatomic ion in KNO3 (potassium nitrate) is NO3- , the nitrate ion. This ion is polyatomic because it contains four atoms bonded together. The nitrate ion is derived from nitric acid, HNO3.
Lithium bromide (LiBr) is a compound, not a cation. The cation is Li+.
Lithium hydroxide is the Arrhenius base that contains the lithium cation.
Li(N03) is the formula of lithium nitrate, Li+ ion and NO3- ion are combined in this salt (compound)
NO3 is a covalently bonded polyatomic ion.
The anion with the formula NO3-1 is a covalently bonded polyatomic ion.
The cation,Mg 2+and the polyatomic anions,2NO3 -form the ionic compoundMg(NO3)2===========magnesium nitrate
It's an ionic substance. Well it's true that ionic substances are usually composed of a metal + a non-metal (or a polyatomic anion), but ionic substances can also be composed of a polyatomic cation + a non-metal (or a polyatomic anion). anion: negatively charged ion cation: positively charged ion

The cation of lithium is Li+.
Lithium Nitrate
The common name for lithium nitrate is simply lithium nitrate.
The polyatomic ion in KNO3 (potassium nitrate) is NO3- , the nitrate ion. This ion is polyatomic because it contains four atoms bonded together. The nitrate ion is derived from nitric acid, HNO3.
Lithium bromide (LiBr) is a compound, not a cation. The cation is Li+.
Li3N would be lithium nitride. LiNO3 would be lithium nitrate. LiN3 does not exist.
