Zusammenfassung: | The present invention relates to a lithium-titanium composite oxide used for an electrode active material. A method for manufacturing a lithium-titanium composite oxide according to the present invention comprises the steps of: preparing a slurry mixture of titanium oxides, lithium, and zirconium; wet-milling the mixture by using beads having a size of 0.10 to 0.30 mm; spray-drying the wet-milled mixture; and calcining the spray-dried mixture. As such, the present invention has the effect of controlling the particle size of a precursor slurry through the milling process by controlling the particle size through wet milling.
La présente invention concerne un oxyde composite de lithium-titane utilisé pour un matériau actif d'électrode. Une méthode de fabrication d'un oxyde composite de lithium-titane selon la présente invention comprend les étapes consistant à : préparer un mélange de suspension d'oxydes de titane, de lithium et de zirconium; broyer par voie humide le mélange en utilisant des billes ayant une taille de 0,10 à 0,30 mm; sécher par pulvérisation le mélange broyé par voie humide; et calciner le mélange séché par pulvérisation. Ainsi, la présente invention a pour effet de réguler la taille de particule d'une suspension de précurseur par le biais du processus de broyage, par contrôle de la taille des particules par broyage humide.
본 발명은 전극활물질에 이용되는 리튬 티탄 복합 산화물에 관한 것으로서, 본 발명에 따른 리튬 티타늄 복합 산화물의 제조방법은 티탄 산화물, 리튬 및 지르코늄이 혼합된 슬러리 혼합물을 제조하는 단계; 상기 혼합물을 0.10 내지 0.30 mm 사이즈의 비드(bead)를 이용하여 습식 분쇄시키는 단계; 상기 습식 분쇄된 혼합물을 분무 건조시키는 단계; 및 상기 분무 건조된 혼합물을 소성시키는 단계를 포함한다. 상기와 같은 본 발명에 따르면, 습식 분쇄를 통해 전구체 슬러리의 입도를 제어함으로써, 분쇄 공정을 통해 입자 크기를 조절할 수 있는 효과가 있다. |
