Underscreening, overscreening and double-layer capacitance
Electrochemistry Communications, 2017 Abstract There have recently been reports of extraordinarily long screening lengths in concentrated electrolytes and which vary non-monotonically with ion concentration. There were several attempts to explain these puzzling observations. In this communication we further explore possibilities to rationalise those results.
