Abstract
⺠A hard carbon electrode in a sodium ion battery was investigated using 23Na NMR. ⺠Two peaks at 10 ppm and 5 ppm and a broad signal of Na in carbon were observed at room temperature. ⺠The signals were assigned to Na stored between disordered graphene sheets and in closed nanopores. ⺠The sodium doesn't have quasi-metallic property in hard carbon.
