FIBROUS CARBON-CONTAINING ELECTRODE MIXTURE LAYER FOR NONAQUEOUS ELECTROLYTE SECONDARY BATTERIES, ELECTRODE FOR NONAQUEOUS ELECTROLYTE SECONDARY BATTERIES COMPRISING SAME, AND NONAQUEOUS ELECTROLYTE SECONDARY BATTERY

摘要

The present invention provides an electrode mixture layer for nonaqueous electrolyte secondary batteries, which contains an electrode active material, a carbon-based conductive agent containing fibrous carbon having an average effective length of 10 μm, and a binder, and which has a thickness of 50 μm or more. This electrode mixture layer has an inner layer portion where the fibrous carbon is three-dimensionally dispersed in a random manner.
