TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: The lithium salt is selected from LiPF6, LiBF4, LiSbF6, LiAsF6 or LiClO4. The anode is made of carbon material capable of occluding or emitting a lithium ion. The cathode is made of lithium-containing oxide.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: The content of the inhibitor against the reaction between the anode and the propionate-based ester is 1-10 wt.% based on the total weight of the non-aqueous electrolyte. The inhibitor against the reaction between the ethyl propionate and the anode is selected from cyclic carbonate with a vinyl group, fluorinated ethylene carbonate, vinylene carbonate, cyclic acid anhydride, compound having a cyclic S=O group, and/or acrylate-based compound. The cyclic carbonate having a vinyl group is selected from 4-vinyl-1,3-dioxolane-2-one, 4-vinyl-4-methyl-1,3-dioxolane-2-one, 4-vinyl-4-ethyl-1,3-dioxolane-2-one, 4-vinyl-4-n-propyl-1,3-dioxolane-2-one, 4-vinyl-5-methyl-1,3-dioxolane-2-one, 4-vinyl-5-ethyl-1,3-dioxolane-2-one, 4-vinyl-5-n-propyl-1,3-dioxolane-2-one and/or 1,3-dioxolane-2-onylmethyl allyl sulfonate. The cyclic acid anhydride is selected from succinic anhydride, maleic anhydride, itaconic anhydride, citraconic anhydride and/or phthalic anhydride. The compound having a cyclic S=O group is selected from cyclic sulfite, saturated sultone, unsaturated sultone, and/or non-cyclic sulfone. The cyclic sulfite is selected from ethylene sulfite, methyl ethylene sulfite, ethyl ethylene sulfite, 4,5-dimethyl ethylene sulfite, 4,5-diethyl ethylene sulfite, propylene sulfite, 4,5-dimethyl propylene sulfite, 4,5-diethyl propylene sulfite, 4,6-dimethyl propylene sulfite, 4,6-diethyl propylene sulfite, or 1,3-butylene glycol sulfite. The saturated sultone is selected from 1,3-propane sultone and/or 1,4-butane sultone. The unsaturated sultone is selected from ethene sultone, 1,3-propene sultone, 1,4-butene sultone, and/or 1-methyl-1,3-propene sultone. The non-cyclic sulfone is selected from divinyl sulfone, dimethyl sulfone, diethyl sulfone, methyl ethyl sulfone, and/or methyl vinyl sulfone. The acrylate-based compound is selected from trimethylolpropane triacrylate, ditrimethylolpropane tetraacrylate, dipentaerythritol hexaacrylate, and/or tris(2-(acryloyloxy)ethyl) iso-cyanurate. The propionate-based ester (I) is selected from methyl propionate, ethyl propionate, propyl propionate, and/or butyl propionate. The lithium salt is selected from LiN(C2F5SO2)2, LiN(CF3SO2)2, CF3SO3Li or LiC(CF3SO2)3.    TECHNOLOGY FOCUS - POLYMERS - Preferred Components: The binding agent includes a water-based binder for the anode having the specific surface area of 1.5-4.5 m2/g. The water-based binder includes a styrene-butadiene rubber (SBR). EXAMPLE - A non-aqueous electrolyte was prepared as following: LiPF6 was added to a mixed organic solvent in which ethylene carbonate (EC) and ethyl propionate (EP) were mixed in a volume ratio of 3:7 to make 1M LiPF6 solution, and then 4-vinyl-1,3-dioxolane-2-one (VEC), a kind of cyclic carbonate having a vinyl group, was added as an anode decomposition inhibitor (2 wt.%). The non-aqueous electrolyte showed high-temperature discharging capacity ratio of 91.2%, low-temperature discharging capacity ratio of 90.7, and OCV (open circuit voltage) reduction at high-temperature preservation of 34 mV.
