Novel (100-x-y)Li3PS4-xLiBF4-yLiCl amorphous solid electrolytes for all-solid-state Li ion battery
Source abstract
Abstract
Amorphous solid electrolytes in the composition (100-x-y)Li 3PS 4-xLiBF 4-yLiCl (x, y: mol%) were prepared using the high—energy ball—milling method. XRD, FT—IR, and solid-state 31P NMR proved the formation of amorphous samples. Peak shifting in FT—IR spectra illustrated the dissociation of LiBF 4 and LiCl. Solid-state 31P NMR demonstrated the formation of highly distorted PS 4 tetrahedral. Those structural characteristics accompanied by electrical conductivity enhancement from 2.8 × 10 −4 Scm −1 of Li 3PS 4 to 6.3 × 10 −4 Scm −1 in 50Li 3PS 4·40LiBF 4·10LiCl solid electrolyte. Besides electrical conductivity, electrochemical stability against Li metal and LiNi 0.5Co 0.2Mn 0.3O 2, operated at high voltage, was also achieved with the existence of LiBF 4 and LiCl in solid electrolytes.
