Firefly Energy Receives Additional $3.3 Million Army Contract for Further Enhancement of Microcell Lead Acid Technology
1 October 2009
Firefly Energy has signed a $3.3 million contract extension for continuing enhancement of its first two advanced battery technology designs. This funding comes in addition to more than $7 million the company has received to date under its original contract to adapt the company’s next-generation microcell foam battery technologies for military applications.
Firefly’s microcell battery technology delivering 4-6 times the lifetime energy compared with traditional Valve Regulated Lead Acid (“VRLA”) batteries. Building on Firefly Energy’s current technology design that enables military equipment to utilize batteries for extensive cycling and energy discharges, Firefly Energy will now significantly increase the power and further enhance the available energy in the military “6T” battery case; the 6T is the vehicular battery used across the US and NATO militaries.
This Army contract extension continues development support of Firefly’s “3D” and “3D2” technologies. The 3D technology replaces traditional lead acid battery negative lead metal electrodes with a three dimensional high surface area microcell foam negative electrode, that exploits the historically unrealized high power potential of lead acid chemistry.
Firefly’s second generation 3D2 battery technology replaces both negative and positive lead metal electrodes with the microcell foam material, providing the potential to match energy density numbers (energy per unit weight) at a delivered pack level that are currently only realized in less environmentally-friendly (and much more expensive) lithium and nickel chemistries, Firefly says. (Earlier post.)
Firefly is developing a portfolio of lead-acid battery technologies and products to enhance performance within major portions of the $30 billion worldwide battery marketplace. The company’s first applied technology is a microcell foam-based battery technology, which can deliver a combination of high performance, low weight and low cost, all within a battery that unleashes the full power potential of lead acid chemistry while overcoming its performance drawbacks.
Firefly is backed by companies such as Caterpillar, BAE Systems and Husqvarna. Additional investors include Chicago-area Venture Capital firm KB Partners, Quercus Trust, Khosla Ventures, Infield Capital, and the Illinois Finance Authority.
