Electrochemical supercapacitors can deliver high levels of electrical power and offer long operating lifetimes 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , but their energy storage density is too low for many important applications 2 , 3 . Pseudocapacitive transition-metal oxides such as MnO 2 could be used to m...
