Title:
リチウムイオン二次電池製造方法
Document Type and Number:
Japanese Patent JP5517009
Kind Code:
B2
Abstract:
A method for producing a lithium-ion secondary battery comprising positive and negative electrodes and a non-aqueous electrolyte solution is provided. The method comprises (A) with several different negative electrode active materials, determining density Xn (g/cm3) at several different number of taps applied, n, respectively; (B) determining density Y (g/cm3) of a negative electrode active material layer constituted with a mixture comprising each negative electrode active material; (C) based on a regression line, Y=aXn+b, determining the number of taps applied, n′, that gives a≰0.5 and a determination coefficient R2≧0.99; (D) based on a plot of Y=aXn′+b, determining a passing range of Xn′ where negative electrode active material layer density Y is in a prescribed range; (E) selecting a negative electrode active material having Xn′in the passing range, and fabricating a negative electrode with this material.
