This invention discloses a sodium-ion battery additive, its preparation method, and its application, belonging to the field of sodium-ion battery technology. The invention first prepares a precursor using a high-temperature solid-state method. During the synthesis of the precursor, a transition metal is oxidized from a low-valence state to a high-valence state, providing a basic crystal framework for the subsequent synthesis of the sodium-ion battery additive, ensuring that no impurity phases are generated in the additive. The precursor is then used to prepare the sodium-ion battery additive, introducing Na during this process. 2 O 2 During sintering, decomposition releases oxygen, ensuring an oxidizing atmosphere inside the sealed crucible and maintaining Ni. 3+ The sodium-ion battery has a stable valence state. The sodium-ion additive prepared by this invention has a lower decomposition voltage and a higher irreversible specific capacity. Therefore, adding a small amount of sodium-ion additive to the positive electrode of a sodium-ion battery can provide more additional capacity, thereby significantly improving the energy density of the sodium-ion battery.
