    • The present invention provides a new redox-active polymer capable of an adequate redox reaction even at low temperature and effectively usable as a high-capacity, high-energy density battery, a large-area electrochromic element, or a biochemical sensor using a microelectrode. This redox-active polymer is of being prepared by polymerizing an aromatic or heterocyclic compound having two or more thiourea groups with an aromatic or heterocyclic compound having two or more isothiocyanate groups. For example, The redox-active polymer may be of being prepared by polymerizing N,N′-1,4-phenylene-bis-thiourea with phenylene-1,4-diisothiocyanate. The redox-active polymer is suitable as an electrode material, particularly a cathode for lithium secondary batteries.
    • 本发明提供了即使在低温下也能够充分发挥氧化还原反应的新型氧化还原活性聚合物,可有效地用作高容量,高能量密度的电池,大面积电致变色元件或使用微电极的生物化学传感器。 该氧化还原活性聚合物通过使具有两个以上硫脲基团的芳族或杂环化合物与具有两个以上异硫氰酸酯基团的芳香族或杂环化合物聚合来制备。 例如,氧化还原活性聚合物可以通过使N,N'- 1,4-亚苯基 - 双 - 硫脲与亚苯基-1,4-二异硫氰酸酯聚合来制备。 氧化还原活性聚合物适合作为电极材料,特别是锂二次电池的阴极。
