Title:
ELECTRODE FOR SECONDARY LITHIUM BATTERY AND SECONDARY LITHIUM BATTERY
Document Type and Number:
Japanese Patent JP2003007305
Kind Code:
A
Abstract:
To obtain an electrode made by stacking on the current collector an active thin films which can electrochemically or chemically occulude and release lithium for a secondary lithium battery, which can restrain deformation such as wrinkles, etc., on the current collector by charging and discharging, and can increase energy density per volume of the battery.
It is featured in that the current collector comprises a copper alloy and has tensile strength of 400 N/mm2 or more, proportional limit of 160 N/mm2 or less, elastic coefficient of 1.1 N/mm2 or more, and surface roughness Ra of 0.01-1 μm for a face of the current collector forming the active material thin film.
