A synthesis method of a lithium-titanium oxide using a solid-phase method comprises the following steps of: mixing lithium oxide (Li_2O) and titanium oxide (TiO_2) in a solvent; separating a solid-phase material including the lithium oxide and the titanium oxide from the solvent; drying the solvent and the separated solid-phase material; and thermally treating the solid-phase material. Provided is the synthesis method of a lithium-titanium oxide using a solid-phase material, which can manufacture particles with fine sizes. 고상법을 이용한 리튬-티타늄 산화물의 합성 방법은 산화리튬(LiO)과 산화티타늄(TiO)을 용매 내에서 혼합하는 단계, 산화리튬 및 산화티타늄을 포함하는 고체상 물질을 용매에서 분리시키는 단계, 용매와 분리된 고체상 물질을 건조시키는 단계 및 고체상 물질을 열처리하는 단계를 포함한다.
