lithium difluorophosphate (lipo2f2) was used as an electrolyte additive to promote the low temperature performance of lini0.5co0.2mn0.3o2/graphite cells. the impact of lipo2f2 on the solid electrolyte interface (sei) film-formation on electrodes was demonstrated by various electrochemical methods and microscopy techniques, such as transmission electron microscopy (tem), scanning electron microscope (sem) as well as x-ray photoelectron spectroscopy (xps), in the pouch cells and half cells. the results showed that the cells containing 1% lipo2f2 performed 71.9% (−20 °c) and 57.93% (−30 °c) of initial capacity, while the cells without lipo2f2 discharged only 49.41% and 9.6% of initial capacity under the same condition. in addition, the enhancement of cyclic performance at 0 °c was attributed to a conductive and stable sei film formed on the graphite by the sacrifice of lipo2f2, which led to a low impedance and richer content of lif and li2co3 in sei components, as depicted in xps.
chemfish has strong advantage to provide lipo2f2 ,please feel free contact us at sales@chemfish.com
