    Author : Priyank Gupta; Peter Gudmundson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lithium-ion batteries; constitutive modeling; U-shape bending tests; electrochemistry; multi-scale modeling; three-dimensional laminate theory.; Solid Mechanics; Hållfasthetslära;

    Abstract : Over the last few decades, rechargeable lithium-ion batteries have been extensively used in portable instruments due to their high energy density and low self-discharge rate. Recently, lithium-ion batteries have emerged as the most promising candidate for electric vehicles and stationary energy storage. READ MORE

  5. 13. 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

  6. 14. Wood-Based Nanocellulose In Lithium Ion Batteries and Electrochemical Coatings
