NOVELTY - The electrolyte comprises dinitrile compound formed with vinylene group or vinyl group. The vinylene group or the vinyl group is formed with lithium salt and ionizable organic solvent, where the vinylene group or the vinyl group is made of compound selected from a group consisting of ethylene carbonate compound, ethylene acrylate compound and sulfonate compound. The ionizable organic solvent is selected from a group consisting of ester, amide, chain carbonate and cyclic carbonate.    USE - Nonaqueous liquid electrolyte for a lithium-based rechargeable battery (claimed). Uses include but are not limited to electric vehicle (EV), cellular phone, camcorder and notebook computer.    ADVANTAGE - The electrolyte effectively reduces bulging phenomenon of the lithium-based rechargeable battery, so that durability of the lithium-based rechargeable battery can be enhanced in a better manner.    DETAILED DESCRIPTION - The dinitrile compound is made of material selected from a group consisting of ethylene glycol bis(2-cyanoethyl) ether, di-ethylene glycol bis(2-cyanoethyl) ether, tri-ethylene glycol bis(2-cyanoethyl) ether, tetra-ethylene glycol bis(2-cyanoethyl) ether, 3,6,9,12,15,18-hexa oxide eicosane dinitrile, 1,3-bis(2-cyanoethoxy) propane, 1,4-bis(2-cyanoethoxy) butane, 1,5-bis pentane, 3,5-di-oxa-heptanedione nitrile, 1,4-bis(cyanoethoxy) butane, bis(2-cyanoethyl) and ethylene glycol bis(4-cyanobutyl) ether. The cyclic carbonate is selected from a group consisting of ethylene carbonate, polypropylene carbonate, 1,2- butylene carbonate, 2,3- butylene carbonate, 1,2- pentylene carbonate, 2,3- pentylene carbonate and vinylene carbonate. The chain carbonate is selected from a group consisting of dimethyl carbonate, diethyl carbonate, dipropyl carbonate, ethyl methyl carbonate, methylpropyl carbonate and ethylpropyl carbonate. The ether is selected from a group consisting of dimethyl ether (DME), diethylether, dipropyl ether, methylethyl ether, methyl propyl ether and ethylpropylether. The ester is selected from a group consisting of methyl acetate, ethyl acetate, propyl acetate, methyl propionate, ethyl propionate, gamma-butyrolactone (GBL), gamma-valerolactone (GVL), gamma-carprolactone, sigma-valerolactone and carprolactone. An INDEPENDENT CLAIM is also included for a lithium-based rechargeable battery comprising a water-based binder.    DESCRIPTION OF DRAWING(S) - The drawing shows a graphical representation illustrating a thickness variance of a lithium-based rechargeable battery according to time.'(Drawing includes non-English language text)'
