The binder effects on the electrochemical performance of the SMG/LiFePO4 18650-battery are evaluated. Using SBR/CMC binder reduces the first-cycle irreversible capacity loss and most surprisingly enhances the high-temperature (55?C) cycle-life of the battery. Surface analyzes suggest that the enhancements are consistent with reduced formation of the solid-electrolyte-interphase (SEI) layer on graphite anode, indicating that composition of binder can have significant influence on SEI formation on anode. ? 2012 The Electrochemical Society. |
