摘要：
A Lithium-ion secondary battery (100A) has a negative electrode current collector (241A) and a negative electrode active material layer (243A) coated on the negative electrode current collector (241A). The negative electrode active material layer (243A) contains negative electrode active material particles (710A). The negative electrode active material particles (710A) include graphite particles each at least partially covered by an amorphous carbon film (750). The weight ratio X of the amorphous carbon film (750) in the negative electrode active material particles (710A) is 0.02≤X≤0.06. The negative electrode active material particles (710A) have a linseed oil absorption number Y (mL/100 g) of 35 (mL/100 g)≤Y≤70 (mL/100 g).
