Solid lithium ion conducting electrolytes and methods of preparation

Title: Solid lithium ion conducting electrolytes and methods of preparation

A composition comprised of nanoparticles of lithium ion conducting solid oxide material, wherein the solid oxide material is comprised of lithium ions, and at least one type of metal ion selected from pentavalent metal ions and trivalent lanthanide metal ions. Solution methods useful for synthesizing these solid oxide materials, as well as precursor solutions and components thereof, are also described. The solid oxide materials are incorporated as electrolytes into lithium ion batteries.

Lithium ion conducting ionic electrolytes

Patent Angell, C. Austen ; Xu, Kang ; Liu, Changle

A liquid, predominantly lithium-conducting, ionic electrolyte is described which has exceptionally high conductivity at temperatures of 100.degree. C. or lower, including room temperature. It comprises molten lithium salts or salt mixtures in which a small amount of an anionic polymer lithium salt is dissolved to stabilize the liquid against recrystallization. Further, a liquid ionic electrolyte which has been rubberized by addition of an extra proportion of anionic polymer, and which has good chemical and electrochemical stability, is described. This presents an attractive alternative to conventional salt-in-polymer electrolytes which are not cationic conductors.

Lithium ion conducting electrolytes

Patent Angell, Charles Austen ; Liu, Changle ; Xu, Kang ; Skotheim, Terje A.

The present invention relates generally to highly conductive alkali-metal ion non-crystalline electrolyte systems, and more particularly to novel and unique molten (liquid), rubbery, and solid electrolyte systems which are especially well suited for use with high current density electrolytic cells such as primary and secondary batteries.

Methods for using atomic layer deposition to produce a film for solid state electrolytes and protective electrode coatings for lithium batteries

Patent Elam, Jeffrey W. ; Meng, Xiangbo

A method for using atomic layer deposition to produce a film configured for use in an anode, cathode, or solid state electrolyte of a lithium-ion battery or a lithium-sulfur battery. The method includes repeating a cycle for a predetermined number of times in an inert atmosphere. The cycle includes exposing a substrate to a first precursor, purging the substrate with inert gas, exposing the substrate to a second precursor, and purging the substrate with inert gas. The film is a metal sulfide.
