Title:
ALKALINE DRY BATTERY
Document Type and Number:
Japanese Patent JP2006040701
Kind Code:
A
Abstract:
To provide an alkaline battery excellent in liquid leakage resistance in thae state of over discharge without worsening the liquid leakage resistance in a state of non-discharge/partial discharge, by clarification of an over discharge liquid leakage mechanism and an effective countermeasure thereon.
