Intercalation of polyethylene oxide PEO in layered MPS3 (MÂ =Â Ni, Fe) materials

The new materials were characterized by powder X-Ray diffraction (XRD), Fourier-transformed infrared (FT-IR), differential thermal and thermogravimetric analyses (DTA/TG), energy dispersive X-Ray (EDX), inductively coupled plasma (ICP) and electrochemical impedance measurements. The intercalation compound Li0.96(H2O)0.77(PEO)0.63Ni0.48PS3 shows an ionic conductivity of 0.13 μS/cm, and dc electronic conductivity of ca. 0.1 μS/cm which is twice that of NiPS3.
