Over the past three decades, intensive research activities have focused on development of electrochemical energy storage devices, particularly exploiting concept flow batteries. Amongst these, vanadium redox batteries (VRFB) are an attractive option, which been studied extensively and now being commercialized around world. The performance VRFB system is governed by several critical components namely electrolyte, electrode, ion‐exchange membrane field design. Here, focus mainly recent...
Among the various energy solutions, lithium‐ion batteries (LIBs) play an important role in process of transition from fossil fuels to renewables. However, necessity replace lithium with cheaper alternatives due its scarcity has recently attracted great interest developing sodium‐ion (SIBs). Hence, discovery and development suitable cathode materials that exhibit high specific capacity, good cycling stability, density are actively pursued. Today's SIB technology continues be driven by...
This review exclusively elaborates the unnoticed vision into design, fabrication, mechanism, and investigation of fascinating Ni(OH)<sub>2</sub>-based supercapacitors in an asymmetric fashion.
Research progress in the development of various battery type and supercapacitor materials is discussed from point view Na-ion capacitors.
Two-dimensional (2-D) polymer has properties that are attractive for energy storage applications because of its combination heteroatoms, porosities and layered structure, which provides redox chemistry ion diffusion routes through the 2-D planes 1-D channels. Here, conjugated aromatic polymers (CAPs) were synthesized in quantitative yield via solid-state polymerization phenazine-based precursor crystals. By choosing flat molecules (2-TBTBP 3-TBQP) with different positions bromine...
Modern wearable technologies require highly efficient energy storage devices for improving their performance attributing a controlled shape and flexibility.

Herein for the first time, we have reported performance and characteristics of new high-voltage zinc–vanadium (Zn–V) metal hybrid redox flow battery using a zinc bromide (ZnBr2)-based electrolyte. The Zn–V system showed an open-circuit voltage 1.85 V, which is very close to that zinc–bromine cell. obtained results exhibited voltaic, Coulombic, energy efficiencies 88, 82, 72% at 20 mA.cm–2, respectively, in low-cost microporous membrane was used as separator. However, cell tested Nafion-117...
Abstract A zinc‐bromine redox flow battery (RFB) is highly suitable for high‐energy storage due to its decoupled energy and power generation. However, the poor kinetics reversible behavior of Br 2 /Br − activity are some significant barriers, as a result, system delivers low density. To increase efficiency cell, in present work, bimetallic catalysts deposited on 3D graphite felt network used positive electrode enhancing reaction. The platinum–nickel (PtNi) composition optimized, improved...
