SINTERED COMPACT INCLUDING LITHIUM TITANATE AND LITHIUM TITANATE LANTHANUM, METHOD FOR PRODUCING THE SAME, AND LITHIUM BATTERY
PROBLEM TO BE SOLVED: To provide a sintered compact in which an electrode active material and an oxide based solid electrolyte are combined.SOLUTION: Provided is a sintered compact including lithium titanate having a spinel type crystal structure and/or lithium titanate having a ramsdellite type crystal structure; and lithium titanate lanthanum having a perovskite type crystal structure. This sintered compact can be obtained, e.g., by a method for producing a sintered compact comprising: a step where a mixture of the precursor of lithium titanate and the precursor of lithium titanate lanthanum or a mixture of lithium titanate and lithium titanate lanthanum is molded to obtain a molded body; and a sintering step where the molded body is sintered.SELECTED DRAWING: Figure 8
【課題】電極活物質と酸化物系固体電解質とを複合化した焼結体を提供する。【解決手段】スピネル型結晶構造を持つチタン酸リチウム及び／又はラムズデライト型結晶構造を持つチタン酸リチウムと、ペロブスカイト型結晶構造を持つチタン酸リチウムランタンと、を含むことを特徴とする焼結体を用いる。この焼結体は、例えば、チタン酸リチウムの前駆体と、チタン酸リチウムランタンの前駆体との混合物や、チタン酸リチウムとチタン酸リチウムランタンとの混合物を成形して成形体を得る工程と、前記成形体を焼結する焼結工程と、を含む焼結体の製造方法等により得ることができる。【選択図】図８
