Abstract

Supercapacitors, as a new type of energy storage device, offer advantages such as long service life, high power density, and being clean and pollution-free, making them a current research hotspot. However, the development of supercapacitors is constrained by traditional electrode materials due to their low energy density and poor rate performance. This paper addresses this issue by synthesizing a novel metal organic frameworks (MOFs) and graphene oxide (GO) composite material (Co-BDC@GO-x, x=0, 1, 2, 3), This research found that the amount of GO added has a significant impact on the morphology and performance of the composite material. The introduction of GO can effectively increase the conductivity of the composite, forming more ion and electron transfer channels, thereby improving the electrochemical performance. When the amount of GO added is 2 mg, Co-BDC@GO-2 achieving a high specific capacitance of up to 554.4Fg^-1 at 1Ag^-1, which resulted in a 3.25-fold improvement in performance compared to pure Co-BDC. Moreover, the rate performance is excellent, maintaining 54.5% of the initial specific capacitance from 1Ag^-1 to 20Ag^-1. Experimental results demonstrate that Co-BDC@GO-2 is a potential electrode material for supercapacitors.
