Lithium forms only oxides and not stable peroxide or superoxides, due to small size of Lithium, it has a strong positive field around it. On combination with the oxide anion (O-2), the positive field of lithium ion restricts the spread of negative charge towards another oxygen atom and thus prevents the formation of higher oxide.
