Solid electrolyte ceramic material and solid battery
Provided is a solid electrolyte ceramic material which has more sufficiently high ion conductivity and is capable of more sufficiently suppressing the growth of Li dendritic crystals. The present invention relates to a solid electrolyte ceramic material obtained by sintering solid electrolyte particles, the solid electrolyte ceramic material containing at least Li (lithium), La (lanthanum), Bi (bismuth), and O (oxygen), and having a higher Bi concentration in the vicinity of grain boundaries than in the inside of the particles.
本发明提供一种离子传导性更充分高并且能够更充分抑制Li树突状晶体的生长的固体电解质陶瓷材料。本发明涉及一种固体电解质陶瓷材料，是固体电解质粒子烧结而成的固体电解质陶瓷材料，所述固体电解质陶瓷材料至少含有Li(锂)、La(镧)、Bi(铋)及O(氧)，晶界附近部的Bi浓度比粒子内部的Bi浓度高。
