Construction of porous CuCo2S4 nanorod arrays via anion exchange for high-performance asymmetric supercapacitor
Abstract To push the energy density limit of supercapacitors, proper pseudocapacitive materials with favorable nanostructures are urgently pursued. Ternary transition metal sulfides are promising electrode materials due to the better conductivity and higher electrochemical activity in comparison to...

Abstract To push the energy density limit of supercapacitors, proper pseudocapacitive materials with favorable nanostructures are urgently pursued.

Moreover, an asymmetric supercapacitor using the CuCo2S4 NRAs as positive electrode and activated carbon as negative electrode delivers a high energy density of 56.96 W h kg−1.
