Substituted lithium orthosilicates and solid electrolytes therefrom

摘要

Substituted lithium orthosilicates are provided havingP PA. THE FORMULA ##EQU1## whereinPPW IS 0 TO ABOUT 0. 45,PPX IS 0 TO ABOUT 0.5, ANDPPY IS 0 TO ABOUT 0.35,PPWITH THE PROVISO THAT ONE OR BOTH OF W OR X+ 2Y IS AT LEAST ABOUT 0.1, ANDPPB. THE MONOCLINIC Li.sub.4 SiO.sub.4 crystal structure. These substituted orthosilicates are useful as solid electrolytes in electrochemical cells such as galvanic cells and electrolytic cells.
