Hybrid batteries a well-known electrochemical energy storage technology that comprises of both supercapacitor and battery characteristics at the same time.The hybrid batteries can fulfill the current global energy quest as they have obtained high energy density (battery) and high-power characteristics (supercapacitor). Here, we have demonstrated the effect of synthesis technique on the electrochemical performance of manganese sulfide (MnS) by mainly opting sonochemical and hydrothermal approach. Initially, the electrochemical characterizations of MnS were analyzed in three electrode setup. Electrochemical measurements in particular cyclic voltammetry, galvanostatic charge discharge, and impedance spectroscopy were studied to scrutinize the nature of the electrodes. The hydrothermally synthesized MnS shows battery grade nature with superior specific capacity of 608.08 C/g at 2.2 A/g. On account of high electrochemical performance, the prominent electrode was employed with activated carbon to explore hybrid battery applications. The hybrid device (S2//AC) has revealed exceptional specific capacity of 265 C/g at 2 A/g and 519.8 C/g at 3 mV/s. Also, the S2//AC device manifests remarkable specific power and energy of 1700 W/kg and 62.5 Wh/kg, correspondingly. Furthermore, a simulation approach was used to evaluate the contribution of capacitive and diffusive by applying Dunn's model. The nature of the asymmetric device was also confirmed by calculating its b fitting values. This study shows that the MnS has the potential to be utilized for efficient energy storage systems.

“…In infrared spectroscopy (IR) of Co X S-NC, Co-NC, NC (Figure a), due to stretching vibration of S–S bond and the Co–S bond, Co X S-NC shows intense peaks at 687 cm –1 and 502 cm –1 , proving the existence of Co 1– X S in the carbon spheres. Moreover, it has stronger absorption peaks of −OH and CO, located at 3000–3600 cm –1 and 1500–1650 cm –1 , which increase the polarity by distribution of unsymmetrical electrons charge, resulting in more potent chemisorption of LiPSs.…”

Shuttle effect and sluggish conversion kinetics of lithium polysulfides (LiPSs) have become the bottleneck in lithium−sulfur (Li-S) batteries. Herein, hierarchically porous nitrogen-doped carbon spheres with highly dispersed Co 1−X S nanoparticles (Co X S-NC) as a trapping-catalyst interlayer for high-performance Li-S batteries is proposed. The nitrogen-doped hierarchically porous carbon spheres generate high specific surface area and large pore volume which provide adequate sites for the adsorption of LiPSs and facilitate the good dispersion of Co 1−X S nanoparticles. Nitrogen doping and Co 1−X S modification improve the polarity, which promotes the adsorption and rapid conversion of LiPSs. The exceptional properties of the Co X S-NC interlayer are confirmed with an exceeding low delay rate of 0.031% per cycle after 1000 cycles at 0.5 C and an outstanding retention rate of 78.7% over 300 cycles at 2 C. Even employed with high sulfur loading of 6 mg cm −2 , it also delivers a high initial areal capacity of 5.74 mAh cm −2 at 0.1 C with capacity retention of 4.58 mAh cm −2 after 100 cycles. This research opens up possibilities for the construction of multifunctional interlayers for use in commercial Li-S batteries.

“…The Raman analysis was carried out to understand the chemical structure of MnCoS@NF, as shown in Figure b. The band at ∼467 cm –1 can be attributed to the E g stretching vibration mode of the Co-S bond, whereas the sharp peak at ∼524 cm –1 originates due to Mn-S lattice vibrations of the bimetallic sulfide . To gain insights into the functionalities present in the sample, the FTIR spectrum was recorded and presented in Figure c.…”

A simple single-step electrodeposition technique was followed for the three-dimensional (3D)-interconnected binary metallic manganese-cobalt sulfide nanosheets on nickel foam (MnCoS@NF). The architecture and chemical composition of the as-synthesized binder-free electrodes were analyzed by field-emission scanning electron microscopy (FESEM), high-resolution transmission electron microscopy (HRTEM), X-ray photoelectron spectroscopy (XPS), and X-ray diffraction (XRD). The MnCoS@NF achieves exceptionally high specific capacitance (1952.8 F g–1 at 2 A g–1) along with high cycle stability in a three-electrode cell measurement. Furthermore, an aqueous asymmetric supercapacitor (AAS) device was designed using electrodeposited MnCoS@NF in combination with reduced graphene oxide-coated NF (rGO@NF) as a positrode and negatrode, respectively. This device was able to provide very high specific energy (105.1 W h kg–1) at a specific power (7.25 kW kg–1) along with high cyclic stability (93.9% of specific capacitance retained after 3000 consecutive GCD cycles), which demonstrates its excellent candidature in supercapacitor applications.
