A secondary battery charge control method includes: a charge control step of executing charging by supplying a charge current to a secondary battery; a charge information acquisition step of acquiring information relating to the charging executed in the charge control step; a storage step of storing the information acquired in the charge information acquisition step as charge data; and a charge inhibition determination step of determining whether to inhibit the charging in the charge control step on the basis of the charge data of a previous cycle that have been stored in the storage step when charging in the charge control step is started again after charging in the charge control step has been completed.

Secondary battery charge control method and charge control circuit

One aspect of the present invention pertains to a method for producing a negative electrode for a non-aqueous electrolyte secondary battery, which comprises a paste preparing step of kneading a mixture containing a negative electrode active material, a binder resin having a glass transition temperature within a range from 20 to 40&#xb0; C. and a dispersion solvent to prepare a negative electrode material mixture paste, a paste applying step of applying the negative electrode material mixture paste controlled to a temperature which is at least 10&#xb0; C. higher than the glass transition temperature of the binder resin on a current collector to form a coating film, a coating film drying step of drying the coating film to form a negative electrode precursor, and a rolling step of rolling the negative electrode precursor to prepare a negative electrode having a negative electrode material mixture layer.
