A comparative study of polyacrylic acid and poly(vinylidene difluoride) binders for spherical natural graphite/LiFePO4 electrodes and cells

► Aqueous PAAX (X = H, Li, Na, K) was investigated as an alternative binder to PVDF. ► The suitability of PAAX in SNG12/LiFePO4 was compared to PVDF. ► PAALi has advantages for both electrodes of SNG12/LiFePO4 compared to PVDF. ► SNG12/LiFePO4 full cells with PVDF cycled 223 times with 70% capacity retention. ► SNG12/LiFePO4 full cells with PAALi cycled 847 times with 70% capacity retention.
