  • Patent number: 7083876
    Abstract: A lead-acid battery superior in high-efficiency charging characteristic to conventional lead-acid batteries and a carbon material used in the lead-acid battery having excellent charge acceptability are disclosed. The lead-acid battery uses, as an additive to the anode active material, a simple substance and/or compound thereof, both having a catalysis for desulfurization or a catalyst for SOx oxidation by adding to, or loading on, a carbon material such as active carbon, carbon black, or the like. When the lead-acid battery with an anode containing carbon material is applied to electric cars, various hybrid cars, power storage systems, elevators, electromotive tools and power source systems such as uninterruptible power source, distributed power source and the like, all having high input and output requirements, stable control can be obtained.

  • Publication number: 20050153173
    Abstract: An energy device having high input-output performance, in particular being excellent in low temperature performance. An energy device characterized by storing and discharging electric energy by both a faradaic reaction mechanism wherein mainly the oxidation state of an active material changes and electric charge transfers inside said active material and a non-faradaic reaction mechanism wherein mainly ions are physically absorbed and desorbed on the surface of an active material and resultantly electric charge is accumulated and discharged. Further, output performance at a low temperature is improved by providing an energy device characterized by storing and discharging electric energy by at least two kinds of reaction mechanisms that show low and high reaction rates respectively in faradaic reaction wherein mainly the oxidation state of an active material changes and electric charge transfers to said active material through an electrode interface.
