Title:
NONAQUEOUS ELECTROLYTE SECONDARY BATTERY
Document Type and Number:
Japanese Patent JP3501365
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a nonaqueous electrolyte secondary battery, that can impregnate a positive plate with a sufficient volume of lithium, has light weight, low self-discharging and high energy density, is resistant to its use with heavy load, and is superior in charging and discharging cycle characteristics.
SOLUTION: In a nonaqueous electrolyte secondary battery comprising a vortex-type, wound-around electrode body, the relation for the separator width > anode width > cathode width is set up, and a vacant space is arranged in the center of the wound-around electrode body. Then, the volume of a nonaqueous electrolyte is set to be 2.5-4.5 μl per 1 mAh of discharge capacity of the battery.
