Future : Lead-Carbn = Firefly (Advanced Lead- Acid Battery) Firefly s revlutinary battery technlgy was brn in the Research and Develpment labratry f Caterpillar, Inc., a wrld-renwned manufacturer f heavy equipment Caterpillar has lng been a cnsumer f batteries fr its many heavy equipment prducts. These, by their very nature, put a severe strain n batteries. Ht and cld extreme temperatures, severe vibratin, and prlnged perids f disuse are standard perating cnditins fr heavy equipment batteries. With a new crprate fcus n imprving batteries, CAT electrnics turned the issue ver t their R&D arm.
FireFly Carbn Fam Technlgy (Advanced Lead Acid Batteries) Thrugh material innvatin, Firefly succeeded t ffer Higher Efficiency & Cycle life which brings dwn the ttal cst f wnership Firefly's gal is t manufacture the lwest-cst-f-wnership, energy-strage systems in the wrld This revlutinary technlgy was invented by Mr Kurt Kelly. He was able t cnfigure the material in such a way that it thrived in the harsh lead acid chemistry envirnment Mr. Kurt Kelley
Abut the cmpany Firefly was started in 2003 by Kurt Kelley (Technical) & Few Others Kurt Kelley is the inventr f the technlgy This technlgy was develped in the labs f Caterpillar Cnsidering the ptential f the technlgy, Caterpillar spun f this technlgy t frm Firefly In 2010 New Management bught assets f Firefly Energy
Lead Acid Battery Prblems Crrsin Shedding Sulfatin Cst Effective Slutin Use f Carbn as envisaged by Experts
Kurt is a gelgist, by training. He wanted t use carbn fr slving the prblems f lead acid batteries in 1998. He fund that the Pb acid battery literature is discussing the same in detail.

The Result : Cycle Life
Objective f Research - Firefly 1) Maximize specific energy (energy strage per unit f weight, measured in watthurs per kilgram) ver designated discharge scenaris 2) Maximize the specific pwer (pwer per unit f weight, measured in watts per kilgram) ver designated high rate discharge scenaris 3) Maximize battery life, nt nly in envirnmental durability but mst imprtantly in cycle life (number f pssible charges and discharges) 4) D it all at extremely lw csts
