Oxygen-consuming battery with improved high rate capability

摘要

An oxygen-consuming battery, such as a metal-air cell or fuel cell battery using oxygen from outside the battery as an active material, and having an improved high rate capability is disclosed. After the battery has been put into use, a light sacrificial drain is placed on the battery during periods when the battery is not being used to provide power in order to reduce degradation in rate capability that can occur over time, particularly when the battery is being used intermittently. Also disclosed is a combination of the oxygen-consuming battery and an electronic device that can be powered by the battery.
