ELECTRODE FOR NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY, MANUFACTURING METHOD THEREFOR, AND NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY

This invention provides an electrode for a non-aqueous electrolyte secondary battery and a method for producing the electrode. The electrode includes a current collector and an electrode mixture layer formed on a surface of the current collector, and the electrode mixture layer includes an active material and a binder. The active material comprises first active material particles of substantially spherical shape and second active material particles of non-spherical shape. The second active material particles are particles of the first active material particles crushed and are packed so as to dose gaps between the first active material particles. This invention can provide an electrode for a non-aqueous electrolyte secondary battery in which the electrode mixture layer has a higher packing rate than conventional rates.
