A non-aqueous electrolyte secondary cell provided with: a positive electrode that has a positive electrode active material; a negative electrode; and a non-aqueous electrolyte. The positive electrode active material contains a lithium composite oxide containing Ni, and the non-aqueous electrolyte contains a non-aqueous solvent containing a fluorinated chain carboxylic acid ester and an organochlorine compound. The organochlorine compound is represented by general formula CF.sub.3CH.sub.2CO-CClR.sub.1R.sub.2 (where in the formula. R.sub.1 and R.sub.2 are respectively independent, and are selected from a hydrogen, a halogen, a C1-2 alkyl group, or a C1-2 halogenated alkyl group).

The invention relates to the field of petrochemistry, and specifically to a method for synthesizing high-octane oxygen containing components of motor fuel. The objects of the invention consist in variants of a method for synthesizing high-octane oxygen-containing components of motor fuel from olefin-containing gas mixtures via oxidative non-catalytic conversions using nitrous oxide, and the subsequent condensation and hydrogenation of the produced oxygenates using heterogeneous catalysts. The high-octane components according to the proposed method consist in a mixture of carbonyl compounds (ketones, aldehydes, hydroxy ketones, hydroxy aldehydes) C.sub.2-C.sub.9 and/or branched hydrocarbons C.sub.5-C.sub.9 and/or alcohols in different ratios. Depending on the production method variant, the octane number of a mixture of the proposed high-octane components consists in a value between 100 and 130 RON. The technical result consists in broadening the resource base for the production of high-octane gasolines and of a variety of environmentally-friendly high-octane additives.
