The electrochemical properties of copper sulfide as cathode material for rechargeable sodium cell at room temperature

The addition of iron to Ni3S2 electrode for sodium secondary battery

“…After the first discharge, the electrode surface was covered by a dense film that was different from the surface of an original Ni 3 S 2 electrode. This phenomenon was similar to the previous works of Na/Ni 3 S 2 and Na/Cu 2 S cells and this film might be related to discharged products [9,10]. However, the surface of charged electrode was similar as the original shape.…”

In situ growth of CuS thin films on functionalized self-assembled monolayers using chemical bath deposition

“…Copper sulfide is a p-type transparent semiconductor with metal-like electronic conductive at low temperature [7,8], and has chemical sensing capabilities [3]. Copper sulfide thin films maintain transmittance in the infrared region, low reflectance in the visible region and relatively high reflectance in the near infrared region [9], which has been found many applications, including optical filter [10,11], sensor [12], architectural glazes [2], cathode material [13], catalysis [14], surperionic materials and nonlinear optical materials [15].…”

Synthesis of CuS@CoS2 Double‐Shelled Nanoboxes with Enhanced Sodium Storage Properties

“…[36,37] In the second cathodic scan, two new peaks at 1.91 and 1.49 Ve merge, which are ascribed to the Na + ion intercalation processes of CuS x and CoS x ,r espectively. [32,[34][35][36]38] During the anodic scans,t wo peaks at about 1.58 and 2.15 V are associated with deintercalation of Na + ions from the Na x CuS structure, [34,35,39] and three peaks at 1.87, 1.96 and 2.07 Vr epresent the reverse processes from Co and Na 2 Stothe CoS x . [32,36,38] Figure 5b displays the representative galvanostatic discharge-charge curves of the CuS@CoS 2 DSNBs at 0.1 Ag À1 .R emarkably,t he CuS@CoS 2 DSNBs deliver as table reversible capacity of about 625 mAh g À1 ,w hich is higher than those of the CoS 2 SSNBs and CuS SSNBs (Figure S18), and most CoS x -based anodes.…”
