ELECTRODE FOR NON-AQUEOUS ELECTROLYTE SECONDARY CELL AND NON-AQUEOUS ELECTROLYTE SECONDARY CELL USING SAME

摘要

[Problem] Provided are an electrode for a non-aqueous electrolyte secondary cell in which electroconductivity does not readily fall even when subjected to a press treatment, and a non-aqueous electrolyte secondary cell using same. [Solution] An electrode for a non-aqueous electrolyte secondary cell containing an electrode composite material including an active material capable of absorbing and desorbing lithium, characterized in that porous aluminum having a porosity of 80 to 95% functions as the collector, the electrode composite material is charged in the pores, and the particle diameter (da) of the active material and the pore diameter (dp) of the porous aluminum satisfy da/dp <= 0.10.
