| Abstract | To provide a manufacturing method of active material capable of adjusting the pore size of Si as an active material.SOLUTION: A disclosed manufacturing method of active material includes steps of: preparing LiSi precursor that contains Li element and Si element; and forming pores by extracting the Li element from the LiSi precursor by using a Li extraction solvent. The Li extraction solvent contains two or more selected from the group consisting of ethanol, methanol, and propanol.SELECTED DRAWING: Figure 1
【課題】活物質としてのＳｉの細孔サイズを調整する。【解決手段】本開示の活物質の製造方法は、Ｌｉ元素とＳｉ元素とを含有するＬｉＳｉ前駆体を準備すること、及び、Ｌｉ抽出溶媒を用いて前記ＬｉＳｉ前駆体から前記Ｌｉ元素を抽出して空隙を形成すること、を含み、前記Ｌｉ抽出溶媒が、エタノール、メタノール、及び、プロパノールからなる群より選択される２種以上を含むものである。【選択図】図１ |
