Abstract
None:
In this study, graphene-wrapped poly(1,4,5,8-naphthalenetetracarboxylic sulfonyl)imine (PNSI/EG) served as a redox-active anode material for aqueous zinc-ion batteries (AZIBs). It yielded a reversible and stable capacity of 173.3 mAh g-1 at 0.1 A g-1, enabling a Zn-metal-free AZIB to deliver a high energy density of 50.1 Wh kg-1.

A battery is a galvanic cell that is used as a source of electrical power for specific applications. Modern batteries exist in a multitude of forms to accommodate various applications, from tiny button batteries such as those that power wristwatches to the very large batteries used to supply backup energy to municipal power grids. Some batteries are designed for single-use applications and cannot be recharged (primary cells), while others are based on conveniently reversible cell reactions that...

On comparing the reactivity of silver and lead, it is observed that the two ionic species, Ag+ (aq) and Pb2+ (aq), show a difference in their redox reactivity towards copper: the silver ion undergoes spontaneous reduction, while the lead ion does not. This relative redox activity can be easily quantified in electrochemical cells by a property called cell potential. This property is commonly known as cell voltage in electrochemistry, and it is a measure of the energy which accompanies the charge...
