Examples
example 1
[0097] By mixing primary particles formed of needle coke-type artificial graphite and having an average particle diameter (D50) of 9.0 μm and an aspect ratio ranging from 1 to 5 with binder pitch in a weight ratio of 9:1 and making them Agglomerated to prepare a secondary particle negative active material having an average particle diameter (D50) of 20.5 μm. In the negative electrode active material, the ratio of the average particle diameter (D50) of the secondary particles / the average particle diameter (D50) of the primary particles was 2.28.
example 2
[0099] By mixing primary particles formed of needle coke-type artificial graphite and having an average particle diameter (D50) of 5.0 μm and an aspect ratio ranging from 1 to 5 with binder pitch in a weight ratio of 8:2 and making them Agglomerated to prepare a secondary particle negative active material having an average particle diameter (D50) of 13.5 μm. In the negative electrode active material, the average particle diameter (D50) of the secondary particles / average particle diameter (D50) of the primary particles was 2.70.
example 3
[0101] By mixing primary particles formed of needle coke-type artificial graphite and having an average particle diameter (D50) of 9.0 μm and an aspect ratio ranging from 1 to 5 with binder pitch in a weight ratio of 9:1 and making them Agglomerated to prepare a secondary particle negative active material having an average particle diameter (D50) of 18.4 μm. In the negative electrode active material, the average particle diameter (D50) of the secondary particles / average particle diameter (D50) of the primary particles was 2.04.
