Negative electrode for non-aqueous electrolyte secondary battery

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

• a collector;
• a first active material layer;
• a binder layer;
• and
• a second active material layer, in an order of the 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 in the first active material layer has a bimodal particle size distribution;
• the negative electrode active material in the second active material layer has a monomodal particle size distribution;
• a mass fraction of the binder in the first active material layer is lower than a mass fraction of the binder in the second active material layer;
• the negative electrode active material contains artificial graphite and natural graphite;
• the natural graphite has a larger aspect ratio than the artificial graphite;
• the negative electrode active material in the first active material layer substantially consists of the artificial graphite;
• the negative electrode active material in the second active material layer substantially consists of the natural graphite;
• an alignment angle of the negative electrode active material in the second active material layer is larger than an alignment angle of the negative electrode active material in the first active material layer;
• the alignment angle indicates an acute angle between a major axis diameter of the negative electrode active material and a surface of the collector;
• and
• a mass fraction of the binder in the binder layer is higher than the mass fractions of the binder in the first active material layer and the second active material layer.
