ELECTRODE LAMINATED BODY, SINTERED BODY, AND MANUFACTURING METHOD THEREOF
To provide a method of co-sintering an oxide including lithium and titanium having a spinel type crystal structure and an oxide having a NASICON type crystal structure while suppressing side reactions.SOLUTION: An electrode laminated body 11 is obtained by laminating an electrode layer 13 including an electrode active material and a separator layer 15 including a solid electrolyte in this order, and the electrode active material is an oxide which has a spinel type crystal structure, and in which the constituent element ratio is LiMTiO(0≤x≤2, 0
【課題】スピネル型結晶構造を持つリチウムとチタンを含む酸化物と、ナシコン型結晶構造を持つ酸化物とを、副反応を抑えながら共焼結する方法を提供する。【解決手段】電極活物質を含む電極層１３と、固体電解質を含むセパレータ層１５とがこの順に積層してなり、前記電極活物質が、スピネル型結晶構造を持ち、構成元素比がＬｉｘＭｙＴｉｚО４（０≦ｘ≦２、０＜ｙ≦２、１≦ｚ≦１．５、Ｍはチタン以外の２価あるいは３価の金属元素、Ｍの価数をｎ価としてｘ＋ｎ×ｙ＋４×ｚ＝８である。）である酸化物であり、前記固体電解質が、ナシコン型結晶構造を持つ酸化物であることを特徴とする電極積層体１１を用いる。【選択図】図１
