PURPOSE: A negative active material composite for a lithium rechargeable battery is provided to prevent the generation of severe irreversible discharge capacity in initial charge-discharging, thereby preventing the degradation of capacity and performance of the lithium rechargeable battery. CONSTITUTION: A negative active material composite for a lithium rechargeable battery is formed by mixing a nitrate transition metal lithium compound into a negative active material with severe irreversible discharge capacity in a proper ratio, wherein the nitrate transition metal lithium compound is formed by adding transition metal atom for imparting electroconductivity to lithium nitride(Li3N). The negative active material composite for a lithium rechargeable battery is configured to reduce an initial irreversible generation capacity. |
