ENERGY DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an energy device having a high input/output characteristic and an excellent characteristic particularly at low temperature.

SOLUTION: This energy device is characterized by storing/releasing electric energy by reaction mechanisms of both a faradic reaction wherein an oxidation state of an active material mainly changes and charge moves into the active material and a non-faradic reaction for mainly storing/releasing charge by physically adsorbing and desorbing ions to/from a surface of the active material. An output characteristic at low temperature is improved by manufacturing the energy device characterized by storing/releasing electric energy by at least two kinds of reaction mechanisms comprising one having a small reaction rate and the other having a large reaction rate in the faradic reaction wherein an oxidation state of an active material mainly changes and charge moves to the active material through an electrode interface. The energy device is characterized by storing and releasing electric energy by at least two kinds of reaction mechanisms comprising one having a small reaction rate and the other having a large reaction rate in the faradic reaction wherein an oxidation state of an active material mainly changes and charge moves to the active material through an electrode interface.
