To obtain an ion conductor, a compound or its salt, an electrochemical device and an ion conductor having high practicality, etc.
The ion conductor has a bicontinuous cubic liquid crystal structure. The practical ion conductor is obtained without performing an alignment control by virtue of a three-dimensional isotropy caused by a bicontinuous cubic liquid crystal structure. A one-dimensional ion channel is spontaneously formed even without performing a specific molecular alignment control and ions are moved in the direction between electrodes. The ammonium salt structure of the compound has excellent compatibility with a lithium salt, an ionic liquid, etc., mixing with the lithium salt, etc., exhibits higher ionic conductivity. The actualization of the ionic conductivity does not require a high-vacuum process. Consequently, the compound has a wide application range as an electrolyte for various energy devices such as a lithium ion battery, solar battery, fuel battery, capacitor, etc., and an ion conductor for an ionics device.
