A study of the performance of the combination of energy storage fibres

Fibre supercapacitors were manufactured using a motor-driven setup. Their electrochemical properties were characterised. The performance of two fibre supercapacitors in series or in parallel mainly followed the expected theoretical models. The electrochemical potential window of a series circuit of two fibre supercapacitors is 1.6 V, which is twice of the working potential of the individual fibre supercapacitors, and the charge-discharge current of two fibre supercapacitors in parallel is also twice of the current for a single one.
