DOE SELECTS WESTINGHOUSE TO DEVELOP ZINC-AIR CAR BATTERY

 PITTSBURGH, Dec. 15 /PRNewswire/ -- The U.S. Department of Energy's (DOE) Sandia National Laboratories have awarded a contract to Westinghouse Electric Corporation's (NYSE: WX) Science & Technology Center here for research on an electrically rechargeable zinc-air vehicular battery.
 Goal of the two-year, $1.9-million effort -- partially cost-shared by Westinghouse -- is to develop an advanced battery system that is simple to manufacture and uses low-cost materials while providing vehicles with better acceleration and about four times the range of today's lead-acid batteries.
 The award gives Westinghouse the U.S. lead in metal-air battery development, a company official said, building on more than two decades of investigation that had emphasized iron-air battery systems.
 "The zinc-air system has always had energy and power densities inherently higher than iron, which translates into greater range and acceleration," said Westinghouse advanced batteries manager Howard E. Saunders. "But we had serious concerns about zinc-air's life-cycle prospects until recent work on long-life zinc electrodes reported by the Lawrence Berkeley Laboratory."
 Dr. Saunders said that the critical component of the Westinghouse zinc-air battery will be an electrically rechargeable air electrode that the company developed for its iron-air program, which was also supported by DOE. "Most air electrodes in use today cannot be recharged and must be discarded after a single use," he said.
 Like internal combustion engines, metal-air batteries work by drawing oxygen from the air to consume fuel. In the case of the batteries the fuel is the metal, which comprises the positive electrode, or anode.
 In the Westinghouse design, air is blown over the negative electrode, or cathode, made of carbon with special catalysts. Current is produced by the electrochemical reaction of oxygen from the air with zinc ions dissolved in the battery's potassium hydroxide electrolyte, forming zinc hydroxide. The reaction is reversed upon recharging.
