摘要：
In this paper, we investigate the effect of hydrochloric acid on the energy storage characteristics of nickel-based metal-organic framework (Ni-MOF) nanostructures. Electrochemical tests reveal that Ni-MOF exhibit high capacitance under hydrochloric acid regulation, achieving a current density of 2567.23 F/g at 2 A/g in 1 ml. Additionally, the synthesized Ni-MOF demonstrate low electrical resistance, with a resistance (Rs) of 1.209 Omega at a hydrochloric acid volume of 1 ml. After 5000 cycles of galvanostatic charge-discharge testing, the cycle retention efficiency of Ni-MOF-0.5 ml remains at 85.71 %.
