ALL-SOLID LITHIUM BATTERY POSITIVE ELECTRODE, AND SECONDARY BATTERY INCLUDING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide: an all-solid lithium battery positive electrode which can be prevented from being destroyed structurally owing to the volume expansion of an active material caused in charging/discharging the battery, and which can keep a stable structure even while its volume is expanded; and an all-solid lithium battery arranged by using such a positive electrode.SOLUTION: A nano composite in which solid electrolyte is uniformly disposed in mesoporous conductive material pores is produced. The surface of a lithium compound comprising one of S, Se and Te which are nonmetallic solid is coated with the mesoporous conductive material-solid electrolyte nano composite, thereby fabricating a single composite of mesoporous conductive material-solid electrolyte-LiX. The single composite is utilized as a positive electrode to make an all-solid lithium battery positive electrode. An all-solid lithium battery comprises the positive electrode.SELECTED DRAWING: Figure 2
