Li3/8Sr7/16Ta3/4Zr1/4O3\n(LSTZ), in which A and B cations of SrZrO3 are partially substituted by Li and Ta, has been reported to be more stable against the lithiated negative electrode than LLT. In this paper, we synthesized LSTZ by using “powder-bed sintering” method, which is commonly used for preparation of dense garnet-structured lithium-ion conductor\nLi7La3Zr2O12 (LLZ). At sintering process, the LSTZ pellet was covered with the same mother powder to suppress the excess Li loss during high temperature treatment and the formation of secondary phases. For LSTZ sintered with covering LSTZ mother powder, secondary phases such as SrTa2O6 and Sr2Ta2O7 were significantly reduced and LSTZ grains in the pellet were in good contact with each other. According to these improvement, the bulk and total (bulk + grain-boundary) ionic conductivity at 27°C of LSTZ attained to 3.5 × 10-4 Scm-1 and 2.7 × 10-4 Scm-1, respectively. The total conductivity at room temperature is approximately 3 times higher than that as\npreviously reported and comparable with LLT and LLZ.", "subitem_description_type": "Abstract"}]}, "item_10001_publisher_8": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "Elsevier"}]}, "item_10001_relation_14": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type": "isVersionOf", "subitem_relation_type_id": {"subitem_relation_type_id_text": "10.1016/j.ssi.2014.04.005", "subitem_relation_type_select": "DOI"}}]}, "item_10001_relation_17": {"attribute_name": "関連サイト", "attribute_value_mlt": [{"subitem_relation_name": [{"subitem_relation_name_text": "ScienceDirect"}], "subitem_relation_type_id": {"subitem_relation_type_id_text": "http://www.sciencedirect.com/science/article/pii/S0167273814001672", "subitem_relation_type_select": "URI"}}]}, "item_10001_rights_15": {"attribute_name": "権利", "attribute_value_mlt": [{"subitem_rights": "Copyright © 2014 Elsevier B.V.
