摘要：

We report the preparation of multi-walled carbon nanotubes (MWCNTs) by using a simple and cost-effective method for supercapacitor applications. The fabricated MWCNTs electrode shows a maximum specific capacitance of 278 F g1 at 1 A g1 and 257 F g1 at 5 mV/s. Also, excellent retention has been achieved in the fabricated MWCNT electrode and 97 % capacitance is retained even after 10,000 cycles. The findings highlight the potential of pyrolysis-synthesized MWCNTs as a viable electrode material for supercapacitors, offering a pathway towards the development of efficient and durable energy storage devices for various applications.
