  2. 1. The dynamic behavior of the NiMH battery – Creating a versatile NiMH battery model

    Author : Jenny Börjesson Axén; Göran Lindbergh; Henrik Ekström; Erika Widenkvist Zetterström; Paul Albertus; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NiMH batteries; Battery Modeling; OCV hysteresis; NiMH gas phase; P2D model; NiMH batterier; Batterimodellering; OCV hysteres; NiMH gasfas; P2D modell; Chemical Engineering; Kemiteknik;

    Abstract : To facilitate the shift from fossil to renewable energy sources, energy storage is needed to cope with the intermittent nature of technologies such as solar, wind, and wave power. One storage alternative is battery-based stationary energy storage. READ MORE

  4. 2. Characterization and Dissolution of HEV NiMH Batteries

    Author : Kristian Larsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Materials Recycling; Nickel tetracarbonyl; Selective dissolution; Nickel metal hydride; Characterization; Mond; Batteries;

    Abstract : The recycling of batteries is an important issue in a sustainable society where materials recycling of complex products is a necessity. Without an efficient recycling there will be an unnecessary loss of both materials and energy due to inefficient or non-existent recycling. READ MORE

  6. 4. Development of metal hydride surface structures for high power NiMH batteries : Also extended cycle-life and lead to more effective recycling methods

    Author : Yang Shen; Dag Noréus; Andreas Züttel; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Metal hydrides; NiMH batteries; Surface treatment; Ni clusters; Rare earths hydroxides; Oxygen; Hydrogen; Inorganic Chemistry; oorganisk kemi;

    Abstract : By combining alkaline etching of hydrogen storage alloys or their hydrides with a controlled oxidation, it was possible to improve reaction kinetics and accelerate activation of MH-electrodes. Both AB5 and AB2 alloys were studied where A is mixtures of rare earth elements for AB5 alloys and titanium and/or vanadium, zirconium for AB2 alloys; nickel contributes the major part of B.

    Abstract : Nickel metal hydride (NiMH) batteries are used today for applications that can assist in the adaptation toward carbon-neutral energy sources (i.e. hybrid vehicles and smart grids). Recovery of metals such as nickel, cobalt and rare earth elements (REEs) from discarded NiMH batteries is important for economic and/or technological reasons. READ MORE
