Figure 6. Volumetric and areal energy versus average power densities and the shell thickness effect for RGO+CNT@CMC YSCs.
(a) Ragone plots compared with the selected previous fibre-shaped YSCs with solid electrolyte. (b) GCD curves at the current density of 0.1 mA cm−2 for RGO+CNT@CMC fibres with CMC shell thickness of 0 μm (1), 2 μm (2), 10 μm (3) and 25 μm (4).
