Batteries including an electrolyte with a ternary solvent package are disclosed. In various implementations, a lithium-sulfur battery may include a cathode, an anode, and an electrolyte include a ternary solvent package. The anode may be positioned opposite to the cathode. The cathode may include a plurality of regions. Each region may be defined by two or more core-shell structures adjacent to and in contact with each other. The electrolyte may be interspersed throughout the cathode and be in contact with the anode. The ternary solvent package may include 1,2-Dimethoxyethane (DME), 1,3-Dioxolane (DOL), tetraethylene glycol dimethyl ether (TEGDME), and/or one or more additives, such as lithium nitrate (LiNO 3 ), and 4,4′-thiobisbenzenethiol (TBT) or 2-mercaptobenzothiazole (MBT), and approximately 0.01 mol of dissolved lithium bis(trifluoromethanesulfonyl)imide (LiTFSI). |
