Title:
SEALED-TYPE BATTERY
Document Type and Number:
Japanese Patent JP2001345090
Kind Code:
A
Abstract:
To improve the reliability of welding and sealing at a terminal part in a sealed-type battery of film packaged type.
The value (cross-sectional area/distance) of a part to reach an electrode group from a sealing part of a terminal where the heat conductivity is higher is made smaller than that (cross-sectional area/distance) of a part to reach an electrode group from a sealing part of a terminal where the heat conductivity is lower.
