The method includes the steps of: providing at least one lithium ion conductor having a ceramic phase content and amorphous phase content; providing a powder of said at least one lithium ion conductor, the powder having a polydispersity index between 0.5 and 1.5, more preferably between 0.8 and 1.3, and most preferably between 0.85 and 1.15; and at least one of a) incorporating the powder into a polymer electrolyte or a polyelectrolyte and b) forming an element using the powder. | 05-05-2022 |
| 20220140397 | METHOD FOR MANUFACTURING NONAQUEOUS ELECTROLYTE FOR LITHIUM ION SECONDARY BATTERY AND METHOD FOR MANUFACTURING LITHIUM ION SECONDARY BATTERY USING THE NONAQUEOUS ELECTROLYTE - The present disclosure provides a method for manufacturing a nonaqueous electrolyte capable of reducing the increase in electric resistance of a lithium ion secondary battery reusing an electrode. The method for manufacturing a nonaqueous electrolyte for a lithium ion secondary battery herein disclosed includes the steps of: mixing a prescribed organic solvent and a support electrolyte; and immersing a positive electrode active material, which has been previously subjected to a charging treatment as a positive electrode active material of a lithium ion secondary battery, in a mixed solution obtained by such mixing. | 05-05-2022 |
