摘要:
The present invention uses a magnesium-based alloy which is excellent in mechanical workability to be formed thinner than conventional alloys. The present invention provides a lithium secondary battery comprising an electrode assembly and a non-aqueous electrolyte, both accommodated in a metal jacket, wherein the metal jacket is made of a magnesium-based alloy containing lithium in an amount of 7 to 20% by weight; and a metal layer or an insulating layer for preventing corrosion of the metal jacket is formed integrally with the metal jacket on the inner wall thereof.
摘要:
A charge control means (10) provided for a battery charging apparatus (1) conducts protection control for a battery pack (2) by transmitting a signal to an output control switch (14) for turning off an output when a rise rate of the temperature of the battery pack (2) detected based on information from a temperature detection terminal (8) is equal to or more than a predetermined value, or a rise rate of the voltage of the battery pack (2) detected based on information from a voltage detection terminal (9) is equal to or less than a predetermined value.
