Solid electrolyte ceramic and solid battery
Provided is a solid electrolyte ceramic which has excellent ion conductivity and is capable of more sufficiently suppressing an increase in electron conductivity due to the operation of a solid-state battery. The present invention relates to a solid electrolyte ceramic having a garnet-type crystal structure, the solid electrolyte ceramic having a structure represented by the general formula: A [alpha] B [beta] D [gamma] O [omega] (in the formula, A represents one or more elements selected from the group consisting of Li, Ga, Al, Mg, Zn, and Sc, and contains at least Li; b is one or more elements selected from the group consisting of La, Ca, Sr, Ba, and lanthanide elements, and contains at least La; and D represents one or more elements selected from the group consisting of transition elements capable of forming a 6-coordinate with oxygen and typical elements belonging to Groups 12 to 15), and further contains one or more transition metal elements selected from the group consisting of Co, Ni, Mn and Fe, and when the content of D in the formula is set to 100 mol%, the content of Mn in the formula is set to 100 mol%, and the content of Fe in the formula is set to 100 mol%. When the content of Li is X (mol%) and the content of B is Y (mol%), the following relational expression is satisfied: 139 < = y < 150 in the range of 330 < x < = 370.
本发明提供固体电解质陶瓷，具有优异的离子传导性，并且可以更充分地抑制由固体电池的工作引起的电子传导率的上升。本发明涉及具有石榴石型晶体结构的固体电解质陶瓷，具有由通式：AαBβDγOω(式中，A是选自由Li、Ga、Al、Mg、Zn以及Sc组成的组中的一种以上的元素，至少含有Li；B是选自由La、Ca、Sr、Ba以及镧系元素组成的组中的一种以上的元素，至少含有La；D是选自能够与氧形成6配位的过渡元素以及属于第12族～第15族的典型元素组成的组中的一种以上的元素)表示的化学组成，并且还含有选自由Co、Ni、Mn以及Fe组成的组中的一种以上的过渡金属元素，将所述式中的D的含量设为100mol％时，将Li的含量设为X(mol％)、将B的含量设为Y(mol％)时，满足以下的关系式：在330＜x≤370的范围内139≤y＜150。
