  2. 16. Stability Phenomena in Novel Electrode Materials for Lithium-ion Batteries

    Author : Mårten Stjerndahl; Torbjörn Gustafsson; John O. Thomas; Robert M. Kostecki; Uppsala universitet; []
    Keywords : Inorganic chemistry; Li-ion battery; electrode material; intermetallic; AlSb; lithium iron phosphate; lithium iron silicate; photoelectron spectroscopy; Oorganisk kemi;

    Abstract : Li-ion batteries are not only a technology for the future, they are indeed already the technology of choice for today’s mobile phones, laptops and cordless power tools. Their ability to provide high energy densities inexpensively and in a way which conforms to modern environmental standards is constantly opening up new markets for these batteries. READ MORE

  4. 17. Carbon Fibres for Multifunctional Lithium-Ion Batteries

    Author : Johan Hagberg; Göran Lindbergh; Dan Zenkert; Juan Vilatela; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical Engineering; Kemiteknik;

    Abstract : The transportation industry today faces many challenges because of the rapid movement towards electrification. One major challenge is the weight of the battery, which limits the effectiveness of the vehicles. READ MORE

  5. 18. State-of-Health Estimation of Li-ion Batteries: Cycle Life Test Methods

    Author : Jens Groot; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; EV; DVA; ICA; cycle life test; HEV; battery testing; State-of-health; battery model; PHEV; lithium-ion battery; impedance spectroscopy;

    Abstract : Despite a rapid development, cost, performance and durability of the energy storage system are still a hindrance for a wide commercialisation of heavy-duty hybrid electric vehicles (HEV). The purpose of the work presented in this thesis is to investigate how different load cycle properties affect the cycle life and ageing processes of Li-ion cells developed for use in HEVs. READ MORE

  6. 19. Wood-based Materials for Lithium-ion Batteries

    Author : Lu Huiran; Göran Lindbergh; Ann Cornell; Claudio Gerbaldi; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; binder; lignin; TEMPO-oxidized cellulose nanofibrils; flexible paper electrodes; lightweight; eco-friendly; Li-ion batteries; Chemical Engineering; Kemiteknik;

    Abstract : Lithium-ion batteries (LIB) have become very important recently as power sources for portable electronics and electric vehicles. Today non-renewable petroleum-based polymers are used as binders in state-of-the-art LIB. Therefore, it is essential to investigate alternative binders, which are environmentally friendly and inexpensive. READ MORE

  7. 20. Structural Changes in Lithium Battery Materials Induced by Aging or Usage

    Author : Rickard Eriksson; Kristina Edström; Torbjörn Gustafsson; Leif Nyholm; Marca Doeff; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Li-ion batteries; XRD; EXAFS; HAXPES; Chemistry with specialization in Inorganic Chemistry; Kemi med inriktning mot oorganisk kemi;

    Abstract : Li-ion batteries have a huge potential for use in electrification of the transportation sector. The major challenge to be met is the limited energy storage capacity of the battery pack: both the amount of energy which can be stored within the space available in the vehicle (defining its range), and the aging of the individual battery cells (determining how long a whole pack can deliver sufficient energy and power to drive the vehicle).
