Hot Paper: Lithiumphoshpidosilicate - a novel class of lithium ion conductor

W00BZU-newscat-acnm |

The new Li-Si-P ternary phase compounds Li8SiP4 and Li2SiP2 are the starting point of a large compound class. Both compounds form structures based on SiP4 tetrahedral building blocks and reveal a significant lithium ion mobility. The compounds were characterized by XRD and solid-state NMR, and Li ion mobility was investigated by impedance and temperature-dependent NMR spectroscopy.
