Graphical abstractThe balance problem between flexibility and energy density for graphene-based fiber electrodes is solved by using GO with nanosheet size larger than 20μm and Mn3O4 nanocrystals with a size of about 5nm. The assembled device shows excellent volumetric capacitance of 45.5Fcm−3 and a maximum volumetric energy density of 4.05mWhcm−3 in maintaining remarkable flexibility and mechanism property.
| Thermoelectric performance of graphene composited BiSbTe bulks by high pressure synthesis Original Research Article Journal of Alloys and Compounds, Available online 3 May 2017, Pages Yuewen Zhang, Hongan Ma, Bing Sun, Binwu Liu, Haiqiang Liu, Lingjiao Kong, Baomin Liu, Xiaopeng Jia, Xin Chen
Graphical abstractA simple and rapid high-pressure-and-high-temperature (HPHT) method is introduced to synthesize Bi0.4Sb1.6Te3 bulks with various graphene content (0, 0.02, 0.05, and 0.1 wt%) in 30 min at 4 GPa. Multiple microstructures are generated by pressure-quenching, including nanograins and lattice structural disorders. The graphene addition exhibits inverse effect on the thermoelectric performances. A maximum ZT = 1.26 at 423 K is achieved for Bi0.4Sb1.6Te3 with 0.05 wt% graphene at 4 GPa.Image 1
