A new type of tailor-made polymeric additive, poly(ethylene phosphate acrylonitrile), has been proposed as a multifunctional polymeric additive for endowing the carbonate electrolyte with synergistically regulated properties of good flame-retardance, enhanced Li-ion dissociation/transportation behavior and a stable LiFePO cathode electrolyte interphase (CEI) layer. Thus, an ultrahigh stable operation of 1500 cycles at the 20C-rate with a good discharge capacity is obtained.
一种新型的定制聚合物添加剂——聚（乙烯磷酸丙烯腈），已被提议作为一种多功能聚合物添加剂，用于赋予碳酸盐电解质协同调控的性能，包括良好的阻燃性、增强的锂离子解离/传输行为以及稳定的磷酸铁锂正极电解质界面（CEI）层。因此，在20C倍率下可实现1500次循环的超高稳定运行，并具有良好的放电容量。
