(July 2006)Power Technology receives patent to it core battery technology. The Power Technology’s invention is a battery comprised of electrical current collectors constructed of reticulated vitreous carbon, covered with a thin layer of lead tin alloy. The current collectors create up to four times higher surface area for electrochemical reactions to take place, compared to those in a typical Lead-acid battery, which results in a battery with higher efficiency and higher capacity, meaning more electricity is stored and delivered. Joey Jun, Chief Technology Officer of Power Technology, is an inventor and developer of the technology.
