New Process Yields New Supercapacitor Electrodes
University of Tehran researchers at the university’s Nano Fabricated Energy Devices Lab have used an ultra-fast and simple method for the fabrication of different types of copper hydroxide nanostructures. The researchers proposed a fast, simple and low cost electric field enhanced synthesis method can be used for fabrication of high performance Cu(OH)2 nanostructured supercapacitance electrodes.
Applying electric field in the ammonium based solution has been used for the fabrication of different forms of copper hydroxide nanostructures. The supercapacitance performance of synthesized nanostructures has been investigated and high specific capacitance of 178 F/g at scan rate of 20 mVs-1 was obtained. The fast, simple and low cost electric field enhanced synthesis method proposed here can be used for fabrication of high performance Cu(OH)2 nanostructured supercapacitance electrodes.

The supercapacitance performance of synthesized nanostructures has been investigated and obtained a high specific capacitance of 178 F/g at scan rate of 20 mVs-1. The team’s paper has been published in Nano.
Using this technique the high performance copper hydroxide supercapacitor electrodes have been fabricated by conducting electric current in the solution resulting in the efficient nanostructure formation on the copper substrate.
Copper based nanostructures have gained much attention in today’s modern devices. The team used an ultra-fast and simple method for fabrication of different types of these structures. By applying electric field in the ammonium hydroxide based solutions, dense arrays of copper based nanostructures formed in short duration time on the order of below 1 min (or even on the order of just 1 second) have been achieved.
In addition, electrochemical properties of the fabricated nanostructures have been investigated, showing specific and areal capacitances larger than other reports on copper hydroxide electrodes. The team believes that these structures have great potential for energy devices, such as supercapacitors and lithium ion batteries.
Your humble writer doesn’t recall ever posting on something out of Iran. Its refreshing to be reminded that not everyone over there is an extremist. One hopes there are researchers willing to replicate and prove up this team’s work.
After all, one of the most harmful mindsets is “Not invented here.” If some Iranians can make the world a little better place, well, “welcome to it!”
