Abstract: A liquid electrolyte lithium secondary battery cell comprising: —a positive electrode material comprising a lithium transition metal-based oxide powder having a general formula Li1+a ((Niz (Ni0.5Mn0.5)y Cox)1-k Ak)1-a O2, wherein A is a dopant, ?0.025?a?0.025, 0.18?x?0.22, 0.42?z?0.52, 1.075<z/y<1.625, x+y+z=1 and k?0.01; and—an electrolyte composition comprising: a) at least one cyclic carbonate, b) at least one fluorinated acyclic carboxylic acid ester, c) at least one electrolyte salt, d) at least one lithium compound selected from lithium phosphate compounds, lithium boron compounds, lithium sulfonate compounds and mixtures thereof, e) at least one cyclic sulfur compound, and f) optionally at least one cyclic carboxylic acid anhydride.

Abstract: This invention relates to a non-aqueous liquid electrolyte composition suitable for secondary battery cells, especially lithium-ion secondary battery cells. Such electrolyte composition comprises a) at least one non-fluorinated cyclic carbonate and at least one fluorinated cyclic carbonate, b) at least one fluorinated acyclic carboxylic acid ester, c) at least one electrolyte salt, d) at least one lithium borate compound, e) at least one cyclic sulfur compound, and f) optionally at least one cyclic carboxylic acid anhydride, all components being present in specific proportions. It can advantageously be used in batteries comprising a cathode material comprising a lithium nickel manganese cobalt oxide (NMC) or a lithium cobalt oxide (LCO), especially at a high operating voltage.

Abstract: Provided is a method for developing an assessment table which is used as a standard for measuring kinesthetic giftedness of preschoolers, that is, 5 to 7 years old infants, for indexation of the kinesthetic giftedness based on measured data for each section and factor using the assessment table, and for classifying the kinesthetic giftedness into levels, so as to identify and assess detailed abilities and potential of kinesthetic gifted infants.
