[5][6] VSEPR theory would predict a bent shape similar to H2O. Lithium oxide reacts with water and vapor, forming lithium hydroxide and must be isolated from them. Crystalline hydrates are not. A lithium metal oxide (LMO) battery is a specialized form of primary (non-rechargeable) cell developed for use in certain medical, military and industrial applications that require a self-contained power source that is small and lightweight, yet capable of delivering high pulses and high rates of continuous power even after prolonged storage. The close approach of the small lithium ion to the oxygen atom results in the unusually high free energy of formation of the oxide. One of their catastrophic failure modes is the formation of residual lithium compounds on the oxide surface when it is exposed to air. For example, the Li2O content of the principal lithium mineral spodumene (LiAlSi2O6) is 8.03%. 4Li + O2 → 2Li2O (Lithium oxide) It also reacts with the nitrogen to form lithium nitride (Li3N).
