Elektrochemische Vorrichtungen enthaltend Lithiumnitrid-Metalverbindungen in mindestens einer Elektrode eines Elektrodenpaares

摘要

This invention relates to electrochemical devices comprise at least a pair of electrodes and a lithium ion conductive electrolyte provided between the pair of electrodes. At least one of the electrodes comprises a lithium nitride-metal compound having a one-dimensional chain structure. By this, the number of end groups which greatly take part in characteristic degradation of the device can be reduced significantly, ensuring good characteristic properties. The devices include lithium secondary cells, electric double-layer capacitors, and electrochemical display devices.
