All-solid-state polymer electrolyte with plastic crystal materials for rechargeable


Keywords: , , , ,

In this paper, we report the synthesis and properties of a series of composite polymer electrolytes formed by dispersion of a non-ionic organic plastic material succinonitrile (SN) into poly(vinyl alchole) complexed with magnesium acid salt. The addition of SN greatly enhances ionic conductivities of the electrolytes which is due to the high polarity and diffusivity of SN. The integrity of the plastic-crystalline phase is kept at low temperature range in polymer electrolytes. The high solubility of SN on Mg salts is observed by Fourier transform infrared (FTIR) spectra measurement, thus could lead to enhanced magnesium-ion transference number. The battery performances of composite polymer electrolytes at different temperatures are tested and the results are comparable to that of the pure plastic crystal electrolytes. This is perhaps the first report of the room temperature charge–discharge performance on the solid composite polymer electrolyte to the best of our knowledge.
