Title:
BATTERY PACK DESIGN FOR METAL-AIR BATTERY CELLS
Document Type and Number:
WIPO Patent Application WO2000036690
Kind Code:
A3
Abstract:
A high capacity primary (single-use; non-rechargeable) battery pack for high current portable appliances such as cellular phones employs electrochemical cells that use ambient oxygen for one of the electrodes. The pack makes possible a simple low cost design by providing for oxygen supply in a completely passive yet compact configuration. To provide for compactness while providing the high gas exchange rates required of high current devices in a passive air management design, a variety of design tactics are developed and applied in various embodiments. Many types of disposable cells are not rechargeable and can cause dangerous problems in appliances that contain hands-free adapters or chargers, such as cell phones. A protective device is disclosed which either limits charging to the degree that charging can be accepted or prevents charging entirely. Various mechanisms for achieving this result are disclosed.
