NOVELTY - A nonaqueous electrolyte secondary battery (100) comprises positive electrode and negative electrode and separator provided between positive and negative electrode. The negative electrode mixture layer on surface of negative electrode contains negative electrode active material, thickener and binder. The positive electrode and negative electrode are coiled together. The negative electrode active material has an average particle size of 5-20 mu m and fines content of 10-50%. The thickener has viscosity of 4980 mPa.second in 1% aqueous solution.    USE - Nonaqueous electrolyte secondary battery e.g. lithium ion secondary battery is used for power supply of hybrid car, electric car, personal computer and handheld electronic device.    ADVANTAGE - The lithium ion secondary battery has enhanced high-rate deterioration characteristic, favorable peel strength. The negative electrode used has increased porosity.    DETAILED DESCRIPTION - A nonaqueous electrolyte secondary battery comprises positive electrode and negative electrode and separator, which is provided between positive and negative electrode. The negative electrode mixture layer on surface of negative electrode contains negative electrode active material, thickener and binder, and is in unpressed state. The positive electrode and negative electrode are coiled together. The negative electrode active material has an average particle size of 5-20 mu m and fines content of 10-50%. The fines content of the negative electrode material has particle size of 3 mu m or less determined by cumulative frequency. The thickener has viscosity of 4980 mPa.second in 1% aqueous solution. An INDEPENDENT CLAIM is included for manufacture of nonaqueous electrolyte secondary battery.    DESCRIPTION OF DRAWING(S) - The drawing shows overall structure of lithium ion secondary battery.
