“…Ni 3 S 2 has been studied extensively in supercapacitors and active electrocatalysts because of its electrical properties, low cost and high energy storage capability [22][23][24][25]. For example, Zhou synthesized Ni 3 S 2 -nanorod@Ni(OH) 2 core-shell nanostructures on a 3D graphene system for high-value supercapacitors by a hydrothermal reaction [26].…”

To achieve impedance matching for microwave absorption, multi-component powder absorbers have attractive aspects. However, conventional designs require mixing the absorber with an adhesive to coat the protected device, resulting in the risk of the coating peeling, and limiting the potential applications of the absorber and expansion of the production scale. Hence, developing a high-performance absorber with an easy fabrication method and low cost is a significant goal. In this paper, a series of Ni@Ni 2 S 3 foams of varied Ni/S ratios were synthesized by a one-step in situ hydrothermal reaction. The foams of different composition had different morphologies that were investigated by x-ray diffraction, x-ray photoelectron spectroscopy, and scanning electron microscopy. The results reveal that Ni@Ni 2 S 3 foam possesses a wide, effective attenuation bandwidth (< −10 dB reflection loss (RL) from 12.75 to 18.0 GHz)) and an intense RL (−50.7 dB) as an electromagnetic (EM) wave absorber for a thickness of 3.6 mm. In addition, compared to powder absorbers, Ni@Ni 2 S 3 foam possesses unique advantages. With a simplified formation process, it is a promising multifunctional material, which in addition to protecting against EM wave pollution, can improve mechanical properties as a result of the metal skeleton it provides.

“…SCs has already been widely utilized in many fields including consumer electronics [5], vehicles [6] and wearable devices [7]. As is well-known, the electrode materials are the most significant parts of supercapacitors to achieve charge storage [8]. On the basis of the energy storage mechanism of electrode materials, SCs can be classified as two types: (1) electrical double-layer capacitors (EDLCs) with carbon materials as the electrode materials; (2) pseudocapacitors (PCs) with transition metal compounds and conducting polymers as the electrode materials [9].…”

A new carbon-coated nickel sulfides electrode material (NST/CNTs@C) has been synthesized through an easy-to-operate process: NiS2/CNTs which was prepared by a hydrothermal method reacted with BTC (1,3,5-benzenetricarboxylic acid) under the condition of water bath heating to obtain the precursor, and then the precursor was calcined in 450 °C under a nitrogen atmosphere to obtain NST/CNTs@C. The electrochemical performance of NST/CNTs@C has been greatly improved because the formation of a carbon-coated layer effectively increased the specific surface area, reduced the charge transport resistance and inhibited the morphological change of nickel sulfides in the charge–discharge process. Compared with pure NiS2 and NiS2/CNTs, NST/CNTs@C presented great specific capacitance (620 F·g−1 at a current density of 1 A·g−1), better cycle stability (49.19% capacitance retention after 1000 cycles) and more superior rate capability (when the current density was raised to 10 A·g−1 the specific capacitance remained 275 F·g−1).
