Extended Data Fig. 3: Electrochemical characterization of FLBs with and without aligned channels.
From: High-performance fibre battery with polymer gel electrolyte
a,b, Cyclic voltammograms of the FLBs with and without aligned channels at increasing scan rates, respectively. FLBs without aligned channels showed obvious polarizations at high scan rates. The voltage ranges were set within 50 mV near the open-circuit voltage to obtain capacitance currents. c, Specific capacitances of FLBs with and without aligned channels at increasing scan rates. d, Charge–discharge profiles of FLBs with and without aligned channels. The FLB with aligned channels showed much higher specific capacity because of sufficient wetting by the electrolyte through the aligned channels. The electrolyte amounts were around 8 g/Ah.
