A newly designed radical polymer with a polynorbornene backbone and unsaturated derivative of tetramethylpyrrolidine 1-oxyl (PROXYL) as pendant groups displays reversible redox at 3.75 V (vs Li/Li ). The robust polymer design enables the high voltage while maintaining a promising cyclability (over 1000 cycles). The polymer is also beneficial as an additive to the regular lithium iron phosphate electrodes, where the quickly responding organic material facilitates the charging reactions catalytically.
一种新设计的自由基聚合物，具有聚降冰片烯主链和作为侧基的四甲基吡咯烷 1-氧自由基（PROXYL）的不饱和衍生物，在 3.75 V（相对于 Li/Li）处显示可逆氧化还原。强大的聚合物设计使高压成为可能，同时保持了有前途的循环稳定性（超过 1000 次循环）。该聚合物也可用作常规磷酸铁锂电池的添加剂，其中快速响应的有机材料可以催化充电反应。
