Low Power Methanol-Air Battery.
Abstract
An increased need for low power, long life power supplies has become apparent with the development of transistorized military communications and surveillance equipments. In view of this, a set of test specifications approximating characteristic performance requirements was defined in order to establish the feasibility criteria for a low power methanol-air-battery. An energy density of 88 Wh/lb was set as a goal, at a continuous drain of 45 mW for 2,000 hours, with the capability of response to 15 W pulses for 6 seconds at 10-minute intervals. A 9-cell battery stack was fabricated in-house for test and evaluation under the 45 mW/15 W load profile. The teflon-bonded anode was catalyzed with 75% Palladium/25% Platinum and the cathodes catalyzed with silver. The total weight of the battery stack, activated with 655 ml of methanol-electrolyte mixture, was 5.6 lb. Performance is reported.
