Abstract
None:
A polymeric salt-induced gel separator stabilizes Zn anodes via PO43--Zn2+ coordination, forming a robust 3D network. It enables 99.5% CE in Zn||Cu cells and over 2000 h of stable Zn||Zn cycling at 50 mA cm-2/50 mAh cm-2 (89.5% DOD), effectively suppressing dendrite growth and enhancing reversibility of the zinc anode.

The Electrical Double Layer
224
In the region where two bulk phases meet, an intricate electric charge distribution arises due to charge transfer, ion adsorption, molecular orientation, and charge distortion. This complex distribution is commonly referred to as the electrical double layer.When a solid electrode interfaces with ions in an electrolyte solution, the speed of electron transfer dictates the rates of oxidation and reduction. The electrode acquires a charge through the escape of atoms into the solution as cations or...

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...
