NEGATIVE ELECTRODE CURRENT COLLECTOR, NEGATIVE ELECTRODE USING THE SAME, AND NONAQUEOUS ELECTROLYTIC SECONDARY CELL

摘要

A negative electrode current collector for a non-aqueous electrolyte secondary battery comprising copper or a copper alloy, characterized in that the copper or copper alloy has a ratio I200/I111 of an intensity I200 of a peak attributed to (200) plane to an intensity I111 of a peak attributed to (111) plane, which satisfies the equation (1): 0.3 in an X-ray diffraction pattern measured using CuK alpha radiation as a radiation source.
