Salt concentration and charging velocity determine ion charge storage mechanism in nanoporous supercapacitors
To improve supercapacitor performance, mechanisms of operation should be understood. Here the authors identify parameters controlling ion charge storage mechanisms and show that charging initially implies a non-equilibrium ion configuration followed by charge-neutral equilibration.
