Title:
NONAQUEOUS ELECTROLYTE SECONDARY BATTERY AND MANUFACTURING METHOD OF THE SAME
Document Type and Number:
Japanese Patent JP2006278182
Kind Code:
A
Abstract:
To effectively prevent an electrode plate from distortion while simplifying a manufacturing process of nonaqueous electrolyte secondary battery.
The nonaqueous electrolyte secondary battery is provided with an electrode body 10 formed by laminating an anode 1B and a cathode 1A through a separator 3. An electrode plate 1 of the electrode body 10 has a planar flat part 6 and curved corner parts 7 curved in a prescribed radius of curvature. An activator layer 5 is adhered to a core body 4 of the anode 1B. Packing density of the curved corner part 7 of the activator layer 5 of the anode 1B is made smaller than that of the flat part 6, or the curved corner part 7 is made thicker than the flat part 6.
