Abstract Self‐doping strategy is well‐known for enhanced ion transport in electrode materials. Herein we report self‐doped thiophene‐based conducting polymer (SDTP), where the dopant SO 3 − groups function as hanging carrier mimicking a ‘pendulum hand’. It synergistically improves battery performance, ideally mitigating dissolution and enhance diffusion kinetics. The coefficient was determined by three different techniques, i. e., electrochemical impedance spectroscopy (EIS), galvanostatic...

Zinc-based energy storage is increasingly getting attention owing to its outstanding characteristics over the other systems. Their high abundance, user-friendliness, environmental benignity, and low reduction potential which can avoid unwanted hydrogen evolution are some of attractive features. Appropriate membrane selection for zinc-based redox flow battery challenging. Herein we report composite SPEEK (sulfonated polyether ether ketones) with covalent organic frameworks (COF) as a battery....

Uncontrolled stereochemical flipping of the substituents indirectly affects redox chemistry benzoquinone. With this assumption, herein we prepared three different polymers, quinone rings directly bonded (DHBP), boned through a methylene bridge (DHB), and phenyl substituted (DADC). The substitution ring generates stereo-centered sp 3 hybridized carbon center which inhibits uncontrolled stereochemistry. It also electrochemical properties charge storage ability polymer. polymer with (DADC)...

Degrading mechanism demonstrates radical's dimerization, leading to an increase in number of OH groups and material's molecular weight. It inhibits undesirable cross-over electrolytes stabilises redox molecules through substantial H-bonding.

Aqueous zinc ion batteries are a very promisingly emerging class of energy storage devices. They brought to the attention researchers owing abundant resourcefulness, user and environmental friendliness, excellent water compatibility unlike alkaline earth metals. Unfortunately, their research development still in unmatured stage. Few inorganic materials, such as oxides manganese, vanadium, Prussian blue, etc., some materials evaluated cathode for batteries. Even though offer high density...
