FELT OF SODIUM SULFUR BATTERY AND METHOD FOR MANUFACTURING THE FELT

摘要

Provided is a positive electrode material of a sodium sulfur battery having multiple felts with glass fiber soaked stacked, and having a structure having soaking density of glass fiber of each stacked felt being gradually reduced in a stack sequence in a felt arranged on a side facing a solid electrolyte for having density of glass fiber certainly changed in the thickness direction, and for being easily manufactured.
