Abstract
A battery, such as an alkaline battery, that can provide a high energy output at a high rate and that has a relatively high ratio of manganese dioxide to cathode volume is disclosed. The battery can provide high energy output at a high rate when the battery is intermittently subjected to a high energy load.
Claims23
A AA battery, comprising:
- an outer insulating layer;
- an outer wall on the inside of the insulating layer and having an inner surface;
- a conductive layer on the inner surface;
- a cathode adjacent the conductive layer and containing at least 2.8 grams of manganese dioxide per cubic centimeter of cathode volume;
- an anode inside the cathode;
- and
- a separator disposed between the cathode and the anode, wherein the battery takes at least 1.6 hours to discharge from 1.6 Volts to 1.1 Volts according to the pulsed test.
