NOVELTY - A negative mix contains carbon material which occludes and discharges lithium ion, graphite material, a carbon material, and a negative electrode material comprising high-molecular compound, metal oxide particles having a carboxyl group and fluorine resin as binder adhered on negative electrode active-material surface containing composite material comprising graphite material and a metal material. The metal oxide particles contain silica and/or alumina. The high-molecular compound is polyacrylic acid, polyacrylate and/or ethylene unsaturated carboxylic copolymer.    USE - Negative mix is used for lithium-ion secondary battery.    ADVANTAGE - The compact lithium-ion secondary battery containing negative mix has excellent initial stage charging and discharging capacity, quick-charge efficiency and cycling characteristics.    DETAILED DESCRIPTION - A negative mix contains carbon material which occludes and discharges lithium ion, graphite material, a carbon material, and a negative electrode material comprising high-molecular compound, metal oxide particles having a carboxyl group and fluorine resin as binder adhered on negative electrode active-material surface containing composite material comprising graphite material and a metal material. The mass ratio of negative-electrode active material, high-molecular compound and metal oxide particles is 97.5-99.9 or less:0.05 or more-less than 1:0.02 or more-less than 1.5. The metal oxide particles contain silica and/or alumina. The high-molecular compound is polyacrylic acid, polyacrylate, ethylene unsaturated carboxylic copolymer and/or ethylene-unsaturated-carboxylic-acid-unsaturated carboxylic-acid-metallic-salt copolymer. The content of binder is 1-20 %mass with respect to negative mix.    DESCRIPTION OF DRAWING(S) - The drawing shows the sectional view of the lithium-ion secondary battery.
