    摘要： Disclosed are viologen derivatives as an electrochromic material having improved stability and lifetime, a metal oxide electrode including the same, and an electrochromic device using the viologen derivative as an electrochromic material. The viologen derivative includes a suitable regulator group capable of increasing ΔE that is a potential difference between E1 (potential at the first redox reaction) and E2 (potential at the second redox reaction). When ΔE increases, the mole fraction of viologen molecules present in the second reduction state decreases. Therefore, it is possible to lower the mole fraction of viologen molecules present in an irreversibly reduced state at an applied potential, thereby increasing the lifetime of an electrochromic material and an electrochromic device.

    摘要： A secondary battery comprising a cathode, an anode, a separator and an electrolyte that comprises a eutectic mixture formed of: an amide group-containing compound, and an ionizable lithium salt. The anode comprises a metal or metal oxide having a potential vs. lithium potential (Li/Li+) within electrochemical window of the eutectic mixture. Because the secondary battery uses a eutectic mixture as an electrolyte in combination with an anode having a potential vs. lithium potential (Li/Li+) within the electrochemical window of the eutectic mixture, problems such as decomposition of an electrolyte and degradation of the quality of a battery are avoided. Also, due to the thermal and chemical stability, high conductivity and a broad electrochemical window of a eutectic mixture, it is possible to improve the quality as well as safety of a battery.
