Abstract
High‐rate and high‐volumetric pseudocapacitance is generally considered very challenging to achieve. It is reported that a compact polyaniline–graphene hydrogel film can provide a combination of high‐volumetric pseudocapacitance, excellent rate capability, and long cycle life. The pore connectivity, which ensures fast ion transport, and well‐maintained nanostructured polyaniline in the compact electrode is the key.
