Extended Data Fig. 6: Architectures and electrochemical properties of FLBs with increasing numbers of electrode fibres.
From: High-performance fibre battery with polymer gel electrolyte
a–c, SEM images of electrodes with 4, 6, and 8 fibres. The anode fibres were wrapped with separators to prevent short circuits before rotated with the cathode fibres. d, Discharge profiles of FLBs made with increasing numbers of electrode fibres. e, Specific capacities of the FLBs made with increasing numbers of electrode fibres. Error bars show the standard deviations for the results from three samples. Scale bars, 1 mm (a–c).
