QuantumSphere a developer of advanced catalyst materials, electrode devices, and related technologies for portable power and clean-energy applications, has filed a patent for technology that extends the capacity of rechargeable lithium ion batteries up to five times. The patent filing covers a novel electrode structure enriched with nano lithium particles that increases the fuel source in a rechargeable lithium ion battery, thus increasing battery life.
QuantumSphere intends to commercialize the technology to improve next-generation batteries for energy storage, consumer, and transportation applications.
This news follows a previous QuantumSphere battery announcement highlighting the development of a high-rate, paper-thin, nano-enabled electrode for disposable batteries. This earlier breakthrough patent pending air-electrode design increased power output by 320% in zinc-air cells, providing roughly 4x more power than equivalent sized alkaline batteries, and is expected to be commercialized in 2009.
"The electrodes our company is developing will expand battery capacity in a profound way, without a sacrifice in safety. Instead of four hours of operating time on a laptop computer, a single charge could last up to 12 hours and provide users with enough computing time for a complete round-trip flight between Los Angeles and New York," said Kevin Maloney, president and CEO of QuantumSphere. "We believe this is a commercially viable technology that will have a major impact in a variety of consumer, industrial, and transportation applications."
