  2. 6. Diagnosis of the Lifetime Performance Degradation of Lithium-Ion Batteries : Focus on Power-Assist Hybrid Electric Vehicle and Low-Earth-Orbit Satellite Applications

    Author : Shelley Brown; Göran Lindbergh; Robert Spotnitz; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; lithium-ion battery; LixNi0.8Co0.15Al0.05O2; LixMn2O4; LiyC6; ageing; three-electrode measurements; impedance modelling; surface film characterisation; hybrid electric vehicle; low-earth-orbit satellite; litiumjonbatteri; åldring; treelektroduppställning; impedansmodell; ytfilmskarakterisering; hybridfordon; satelliter; Electrochemistry; Elektrokemi;

    Abstract : Lithium-ion batteries are a possible choice for the energy storage system onboard hybrid electric vehicles and low-earth-orbit satellites, but lifetime performance remains an issue. The challenge is to diagnose the effects of ageing and then investigate the dependence of the magnitude of the deterioration on different accelerating factors (e.g. READ MORE

  4. 7. 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
