This work reports on a high-voltage,hybrid capacitor involving two separate redox reactions.Aqueous solutions of Mg（NO3）2and KI have been used for negative and positive electrode,respectively.Adjusting p H ? 2 for electrode（ t） with KI solution and modifying Mg（NO3）2solution to p H ? 9 for negative side play a crucial role for a stable long-term operation of capacitor at enhanced voltage.A benefit from such a construction is a pseudocapacitive contribution from hydrogen sorption reaction on the ...
