Negative electrode for non-aqueous electrolyte secondary battery

A negative electrode for a non-aqueous electrolyte secondary battery, the negative electrode comprising:

• a current collector;
• a first active material layer;
• a binder layer;
• and
• a second active material layer, in order of the current collector, the first active material layer, the binder layer, and the second active material layer, wherein:
• each of the first active material layer and the second active material layer contains a negative electrode active material and a binder;
• the negative electrode active material contains artificial graphite and an Si-based active material;
• the negative electrode active material in the first active material layer substantially consists of the artificial graphite and the Si-based active material;
• the negative electrode active material in the second active material layer substantially consists of the artificial graphite;
• an aspect ratio of the artificial graphite in the first active material layer is larger than an aspect ratio of the artificial graphite in the second active material layer;
• an alignment angle of the artificial graphite in the first active material layer is larger than an alignment angle of the artificial graphite in the second active material layer;
• the alignment angle indicates an acute angle between a major axis diameter of the artificial graphite and a surface of the current collector;
• a mass fraction of the binder in the first active material layer is higher than a mass fraction of the binder in the second active material layer;
• a mass fraction of the binder in the binder layer is higher than a mass fraction of the binder in each of the first active material layer and the second active material layer;
• and
• a void ratio of the first active material layer is higher than a void ratio of the second active material layer.
