Title:
非水系電解質二次電池用電極及びこれを備える非水系電解質二次電池
Document Type and Number:
Japanese Patent JP6804551
Kind Code:
B2
Abstract:
The present invention provides an electrode for nonaqueous electrolyte secondary batteries, which enables the achievement of high output characteristics. An electrode for nonaqueous electrolyte secondary batteries, which is provided with a collector and a positive electrode active material layer that is arranged on the collector and contains a positive electrode active material. The positive electrode active material is configured to contain compound particles which have a layered structure composed of two or more transition metals, and which have an average particle diameter DSEM of from 1 µm to 7 µm (inclusive) based on the observation with an electron microscope, a ratio of the 50% particle diameter D50 in a volume-based cumulative particle size distribution to the average particle diameter DSEM, namely D50/DSEM of from 1 to 4 (inclusive), and a ratio of the 90% particle diameter D90 in the volume-based cumulative particle size distribution to the 10% particle diameter D10 in the volume-based cumulative particle size distribution, namely D90/D10 of 4 or less. The positive electrode active material layer has a void fraction of 10-45%.
