合成了氧化还原活性的吩噻嗪官能化聚合物，并将其用作可再充电电池中有前景的阴极活性材料（类似于3.7 V vs. Li，77 Ah kg（-1））。吩噻嗪和聚合物主链之间较长的间隔基有助于所形成的自由基阳离子的稳定性，导致自放电减速和循环性能改善。
Redox-active, phenothiazine-functionalized polymers were synthesized and employed as a promising cathode-active material (similar to 3.7 V vs. Li, 77 Ah kg(-1)) in a rechargeable battery. The longer spacer between phenothiazine and the polymer backbone contributed to the stability of the formed radical cations, resulting in decelerated self-discharge and improved cycle performance.
