METHOD FOR PRODUCING NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY, NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY, AND METHOD FOR PRODUCING NEGATIVE ELECTRODE PASTE |
摘要 |
A method for producing a non-aqueous electrolyte secondary battery includes: subjecting a mixture of a negative-electrode active material on which oil has been adsorbed, CMC and water to hard kneading to prepare a primary kneaded mixture; diluting the primary kneaded mixture with water to prepare a slurry; and adding a binder to the slurry. The method further includes defining an amount of the oil to a value equal to or more than 50 ml/100 g and equal to or less than 62 ml/100 g, wherein the amount of the oil is an amount at the time when the viscosity characteristics of the negative-electrode active material exhibits 70% of the maximum torque that is generated when the oil is titrated onto the negative-electrode active material. The 1% aqueous solution viscosity of the CMC is defined to a value equal to or more than 6000 mPa·s and equal to or less than 8000 mPa·s. |
