Firefly Energy Inc., developer of an innovative carbon-graphite foam lead acid battery for commercial and military applications (earlier post), announced its second major battery manufacturing partnership in less than two weeks. (Earlier post.)
Crown Battery Company will provide prototype and production support of Firefly battery technology to serve the commercial deep cycle markets. Specific terms were not disclosed.
Firefly’s carbon-graphite lead acid battery technology uses a three dimensional high surface area foam material that enhances the high power potential of lead acid chemistry that was impossible in the past. The porous, conductive nature of the foam electrode enables faster, deeper and more reliable discharges and recharges. Battery life is extended since sulfation is reduced, the carbon-graphite foam makes the battery more environmentally friendly, and the battery is less expensive than lithium and nickel battery chemistries.
Examples of end-use commercial deep cycle applications may include lawn and garden care equipment, electric material handling systems, floor care equipment, renewable energy systems, and marine equipment.
The carbon-graphite foam replacing much of the lead content also enables the battery to perform at cooler temperatures—a key feature considering that the corrosion rate of lead doubles for every 15 degrees the temperature rises above 70-degrees Fahrenheit.
Crown Battery Manufacturing Company is a lead-acid battery manufacturer with more than 75 years of experience.
