  • Publication number: 20220158232
    Abstract: An electrolyte and a fabricating method thereof, and a lithium battery are described. The fabricating method of the electrolyte has steps of: adding a PVDF-based polymer and a PMA-based polymer to a liquid electrolyte to form a mixture, wherein the liquid electrolyte comprises a lithium salt; heating the mixture to between 60 and 100° C. for more than 4 hours, so as to form a transparent solution; and cooling the transparent solution to form the electrolyte. The electrolyte is a gel-state electrolyte between ?60 and 80° C., which is suitable for use as an electrolyte in a lithium battery.

  • Patent number: 11289735
    Abstract: An electrolyte composition, a method of fabricating the same, and an energy storage device with the electrolyte composition are provided. The method of fabricating an electrolyte composition has steps of: mixing a modified polyoxyethylene-based material and a siloxane-based material in a solvent to form a mixture in which a tail end of a group of the modified polyoxyethylene-based material has an amine group; and heating the mixture at a temperature ranging from 50 to 60° C. for a time ranging from 3 to 5 hours for obtaining an electrolyte composition, where the electrolyte composition is formed by bonding the amine group of the modified polyoxyethylene-based material to the siloxane-based material. The electrolyte composition enables conductive ions to conduct in an electrolyte easily.
