| Abstract | Terpene resin (TS) emulsion has been adopted as a tackifier in lithium polyacrylate (PAALi) as water-soluble binder for LiFePO4 (LFP) cathode in Li-ion batteries. TS-PAALi composite binder with optimal ratio of 1:1 (denoted as TS1-PAALi1), shows improved flexibility and enhanced adhesion capability of 0.170 N/cm in comparison with 0.120 N/cm of PAALi after introducing TS as adhesion enhancing agent, which is comparable with that of nonaqueous poly(vinylidene difluoride) (PVDF, 0.171 N/cm) and much better than aqueous sodium carboxymethyl cellulose (CMC, 0.045 N/cm). The electrochemical characteristics of LFP with TS1-PAALi1 have been investigated and further compared with those of PAALi, CMC, and PVDF. LFP with TS1-PAALi1 exhibits superior cycling stability and rate capability, maintaining 65.57% capacity of 0.2 C at 5 C rate in comparison with 60.73%, 57.83%, and 34.79% for PAALi, CMC, and PVDF, respectively. In addition, LFP with TS1-PAALi1 displays excellent cycling performance almost without any capacity fading at 60 degrees C after 45 cycles at 1 C, much better than that of PAALi, CMC, and PVDF. Cyclic voltammetry and electrochemical impedance spectroscopy reveal that LFP with TS1-PAALi1 has a smaller redox potential difference, lower electrode polarization, and a more favorable electrochemical kinetics (fast lithium diffusion rate) than that of PAALi, CMC, and PVDF, thus more superior electrochemical performances.
