On the Charge Storage Mechanism of Conducting Polymers
1987Most conducting polymers are made conductive by doping. However, ever since such systems have been studied it has been recognized that this doping is not comparable to the classical doping of typical inorganic semiconductors. Obviously, the p-doping corresponds to an oxidation and the n-doping to a reduction process.

Applied Physics Reviews, 2023
Pseudocapacitive (PC) materials are under investigation for energy storage in supercapacitors, which exhibit exceptionally high capacitance, good cyclic stability, and high power density. The ability to combine high electrical capacitance with advanced ferrimagnetic or ferromagnetic properties in a single material at room temperature opens an avenue ...

MRS Proceedings, 1995
ABSTRACTThe hydrous ruthenium oxide (RuO2.xH2O) powders with different contents of H20 have been formed by a sol-gel process and have been annealed at different temperatures. It was found that the specific capacitance of RuO2.xH2O is strongly dependent on the crystalline structure.

Revealing the Charge Storage Mechanism in Porous Carbon to Achieve Efficient K Ion Storage
SmallAbstractConstructing a porous structure is considered an appealing strategy to improve the electrochemical properties of carbon anodes for potassium‐ion batteries (PIBs). Nevertheless, the correlation between electrochemical K‐storage performance and pore structure has not been well elucidated, which hinders the development of high‐performance carbon ...
