QuantumSphere Announces Two Key Patent Applications Leveraging QSI-Nano® Catalysts for Large Primary Battery Market
Third-Party Validation Confirms 320% Increase in Power for Zinc-Air Battery Cathodes

QuantumSphere is excited to announce the filing of two groundbreaking patents covering composition of matter and a paper-thin electrode device responsible for achieving a 320% increase in power and efficiency for zinc-air battery cathodes. These filings follow our recently published summary results for low-cost, efficient hydrogen production and complement a consistent stream of recent technology innovations and intellectual property as we continue our development focus on disruptive solutions for portable power and other clean-energy applications.

“In order to accelerate the adoption of these highly-active nano catalyst materials in disruptive solutions for portable power and clean-energy applications, it is critical that significant strides be made in the performance, cost effectiveness and environmental benefits of these devices and processes,” stated Kevin Maloney, CEO, QuantumSphere, Inc. “These are the fundamental requirements that will enable all participants throughout the value chain to gain tangible advantages from the commercialization of portable power and other clean, renewable energy sources. We are actively working with some of the world’s largest corporations to collaborate on achieving those goals, and these filings are the latest step in that ongoing process.”

With these latest patent applications, QuantumSphere is tapping into a potential multi-billion dollar battery market with the goal of delivering significant performance enhancement to disposable zinc-air batteries. Primary zinc-air batteries offer 3-6 times the energy of equivalent size alkaline and rechargeable batteries. Expert electrochemist and lead scientist on the air electrode project, Robert Dopp of DoppStein Enterprises, Inc. (DSE), conducted the electrode development effort and validated the effectiveness of our nano catalysts. “These improvements unlock higher power applications previously viewed as impractical for this class of battery,” commented Robert Dopp. “QSI and DSE collaborated to find the most effective catalyst and several successful ways to implement it into gas-diffusion electrodes. The resulting performance improvement is unambiguous.” Moreover, this dramatic improvement can be achieved with little increase in cost. In addition, this innovation further supports the elimination of mercury and is a direct reflection of the Company’s commitment to the development of environmentally-friendly, portable power solutions. The European Union has recently mandated that all batteries must remove this toxic substance, and the EPA is expected to follow shortly.
