ALUMINUM-AIR (SALT WATER) BATTERY FOR VEHICLES

This report discusses the development of a 12 volt, 250 watt aluminum-air (salt water electrolyte) battery and its use to demonstrate the concept of range extension in electric vehicles using two types of battery. Two 12-v 20-a multicell aluminum-air batteries were constructed and tested in a 24-v series configuration. They yielded 100 wh/kg and 15 w/kg. The problems of heat removal, hydrogen dispersal and by-product management were resolved. The batteries were then placed in parallel with lead-acid batteries in a 24 volt golf cart. A device was developed for the aluminum-air battery to trickle charge the lead acid battery. The hybrid system more than doubled vehicle range as compared to that obtained using lead-acid batteries only, with an equal mass and a similar capacity rating. (a)
