Negative electrode plate for non-aqueous electrolyte secondary battery

Abstract

A negative electrode plate for a non-aqueous electrolyte secondary battery includes a negative electrode substrate and a negative electrode active material layer. The negative electrode active material layer is placed on a surface of the negative electrode substrate. The negative electrode active material layer includes negative electrode active material particles and carboxymethylcellulose. The negative electrode active material particles include graphite. Volume-based particle size distribution of the negative electrode active material particles satisfies relationships of expression (I) “16 μm≤D50≤20 μm” and expression (II) “(D90−D10)/D50≤1”. The carboxymethylcellulose has a weight average molecular weight from 350,000 to 370,000. The carboxymethylcellulose has a degree of etherification from 0.65 to 0.82.
