Are metal ion capacitors a viable alternative for energy storage?
In recent years metal ion capacitors (MICs) and supercapacitors devices have been reported as promising alternatives for energy storage on a large scale.
How does a metal-ion capacitor work?
Although it is pretty clear that a typical metal-ion capacitor has the privilege of using both the electrochemical capacitor technology (due to the EDLC component as one of the electrodes) and metal-ion-based battery electrode, the working mechanism of the overall system could, in fact, be a lot trickier than it might appear to us.
How to compete with monovalent metal-ion capacitors?
To compete with monovalent metal-ion capacitors, in terms of energy density, multivalent metal systems should be employed in their pure metallic form as one of the electrodes. This is an essential parameter for achieving highest possible energy density values from these multivalent metal-ion-based energy storage systems.
Which cathode materials are used in metal-ion hybrid capacitors?
