Zinc-Oxygen Batteries

Matsi, Inc.

Atlanta, GA

High performance, limited (<100) cycle life, sealed rechargeable zinc-oxygen cell

• Developed 10 cycle, sealed zinc-oxygen cell with specific energy nearly equivalent to nickel-cadmium
• Two-layer bifunctional cathode evolved into a two-layer, high-power, single-use cathode
• Individual recyclable single-use cells have delivered 500 Wh/Kg and 1000 Wh/Kg in U.S. Army tests

• In notebook computers, potential for a $30, two pound, 300Wh, single-use battery delivering 20-50 hours of computing power
• 100 million notebooks in use by 2000 means potential retail market of $5 billion
• Negotiated letter of intent with securities broker/dealer for $3-5 million public stock offering
• Also $550,000 grant from DOE to build pilot production line for the improved cathode

• For NASA, potential “life of mission” batteries for the Wireless Crew Communications System (WCCS), video camcorder and a custom astronaut “universal power pack”
• For Navy, potential mission extension (4x) replacements for silver-zinc batteries in unmanned underwater vehicles
