“…The cathode half‐cell reaction, which occurs when the sulfur cathode is converted to lithium sulfide during discharge, can be written as follows:

S + 2 {Li}^{+} + {normale}^{-} \leftrightarrow {Li}_{2} S

When the cathode is being charged, intermediate polysulfide production takes place, such as, 89

The creation of effective and clean energy storage technologies has advanced dramatically due to growing worldwide worries over the depletion of fossil fuels and environmental issues. Energy storage and conversion systems have emerged as a crucial component with the development of numerous electronic devices, enabling the devices to function for extended periods of time. Due to their enormous surface area, strong electrical conductivity, and ion transport, 3D self‐supported nanoarchitectures associated with electrochemical energy storage (EES) devices can offer alternatives for enhancing the performance and advancement of existing EES systems. Here, we present the results of our findings regarding the design, production, and use of self‐supported 3D nanostructures in energy storage and conversion systems such as supercapacitors, batteries, solar cells, and fuel cells. A variety of advanced 3D nanomaterials may be readily created on an immense scale using various synthetic techniques, and they have a great deal of potential for use as electrodes in energy storage and conversion devices with much better performance. These fabrication techniques include electrochemical deposition, electrospinning, chemical precipitation, spray pyrolysis, sol‐gel method, hydrothermal method, chemical vapor deposition, and so forth.

“…This demand for balanced energy and power-efficient devices has created opportunities and opened up the area for research in the eld of battery-capacitor hybrid devices like lithium-ion capacitors. [1][2][3][4][5][6][7][8][9][10][11] But the main challenge with hybrid devices is the difference in the mechanism and kinetics of charge storage at both the electrodes and balancing them for optimum performance. LIBs store charge through redox insertion into the bulk of the electrode, and so the time scale for the reaction is larger.…”

LiNi0.5Mn1.5O4 (LNMO) has the advantages of high voltage output (4.7 V), fast charging capability, and better thermal stability, which make it suitable for future applications in lithium-ion batteries. However, the limitation in cycle life due to the electrolyte and the structural instability during high-voltage cycling to 5 V is a major drawback. Further, the decomposition of the electrolyte on the highly reactive surface of LNMO plays a critical role in catalyzing the structural disintegration. The issue can be mitigated via the surface carbon coating on LNMO. Herein, a method to integrate soft carbon on LNMO is reported, which bypasses the drawback of lattice oxygen loss during the conventional carbon coating on metal oxides. The soft carbon derived from the pitch precursor with its unique blend of physical properties renders the LNMO surface less susceptible to electrolyte attack. As a result, capacity retention enhances by 25.6%, and the coulombic efficiency improves by 1.5% over 500 cycles in a carbonate-based 1 M LiPF6 electrolyte. The soft carbon regulates the interfacial composition balanced in LiF/Li x PO y F z and reduces the growth of the charger-transfer resistance. Moreover, the strategy also decreases the Mn dissolution by 18%.
