TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Composition: The content of halogenated cyclo carbonyl compound is 0.05-0.5 mass% with respect to non-aqueous electrolyte. The electrolyte solution further contains halogenated carbonate such as fluoroethylene carbonate, or carbonate having carbon-carbon multiple bond such as vinylene carbonate.    TECHNOLOGY FOCUS - POLYMERS - Preferred Composition: The non-aqueous-electrolyte secondary battery further comprises high molecular compound such as polyvinylidene fluoride swollen with electrolyte solution. Preferred Film: The non-aqueous-electrolyte secondary battery has laminate film as exterior component. EXAMPLE - Lithium cobalt complex oxide (in weight parts) (94), polyvinylidene fluoride (3), N-methyl pyrrolidone (3), graphite and binder were mixed, to obtain anode-mix coating liquid. The obtained anode-mix coating liquid was uniformly coated on both surface of aluminum foil top having thickness of 20 mu m and dried, to form anode-mix layer of 20 mg/cm2 per single surface. The anode-mix layer was cut in the shape of width 50 mm and length 300 mm, to obtain positive electrode. Graphite (97), polyvinylidene chloride (3), N-methyl pyrrolidone and binder were mixed, to obtain cathode-mix coating liquid. The cathode-mix coating liquid was coated on copper foil top having thickness of 15 mu m and dried, to form cathode-mix layer of 10 mg/cm2 formed on both surfaces. The cathode-mix layer was cut into shape of width 50 mm and length 300 mm, to obtain negative electrode. Ethylene carbonate, ethylmethyl carbonate, lithium-hexafluorophosphate and 2-chloro cyclohexanone were mixed in the mass ratio of 34, 50.7, 15 and 0.3 respectively, to obtain electrolyte solution. The positive electrode and negative electrode were laminated, wound up through separator comprising microporous polyethylene film having thickness of 9 mu m, added into bag comprising aluminum laminate film, electrolyte solution (2 g) was added and bag was heat sealed, to obtain lamination-type battery. The battery had capacitance of 700 mAh, and excellent charging and discharging characteristic and cyclic characteristic.
