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.
