  1. 11. State-of-Health Estimation of Li-ion Batteries: Ageing Models

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

    Abstract : Significant research efforts are being made to understand, and ultimately mitigate, thedegradation of Li-ion batteries upon usage. Currently, battery ageing models are used inorder to optimise the battery usage and to achieve robust battery solutions. READ MORE

  2. 12. Sustainable recycling of Li-ion batteries

    Author : Jędrzej Piątek; Adam Slabon; Tetyana Budnyak; Reza Younesi; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; batteries; recycling; metal recovery; adsorption; electrochemistry; oorganisk kemi; Inorganic Chemistry;

    Abstract : Lithium-ion batteries (LIBs) play a key role in today’s energy storage sector, finding applications in everyday use electronic devices, like smartphones, laptops or electric vehicles. Despite very good properties, such as high electric capacity and high number of charge-discharge cycles, eventually each battery in the world will be disposed and stored in a landfill, waiting for the opportunity to be recycled.

  3. 13. A scalable furnace technique to grow silicon nanoparticles for high-performance Li-ion battery anodes

    Author : Rohan Patil; Jonas Örtegren; Shizhao Xiong; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Li Ion Battery; Aerogel-Based Anodes; Novel Method; silicon nanoparticles; Nanographite; High Capacity;

    Abstract : Lithium-ion batteries are one of the key technologies to address the global climate challenge. Higher battery capacity could also be seen as indirectly influencing the entire value chain. One way to increase capacity is to add silicon to the graphite anode, since silicon can store much more lithium ions than graphite. READ MORE

  4. 14. Methods for Testing and Analyzing Lithium-Ion Battery Cells intended for Heavy-Duty Hybrid Electric Vehicles

    Author : Pontus Svens; Göran Lindbergh; Mårten Behm; Søren Juhl Andreasen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Li-ion; battery; hybrid electric vehicle; Chemical Engineering; Kemiteknik;

    Abstract : Lithium-ion batteries designed for use in heavy-duty hybrid vehicles are continuously improved in terms of performance and longevity, but they still have limitations that need to be considered when developing new hybrid vehicles.               The aim of this thesis has been to study and evaluate potential test and analysis methods suitable for being used in the design process when maximizing lifetime and utilization of batteries in heavy-duty hybrid vehicles.

  5. 15. Assessment of safety characteristics for Li-ion battery cells by abuse testing

    Author : Carl Fredrik Larsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; overcharge; Lithium-ion; toxic gases; abuse test; thermal runaway; short circuit; safety; battery; fire;

    Abstract : Despite the many advantages with lithium-ion batteries there can be disadvantages in form of safetyissues. In an abuse situation a Li-ion cell can undergo a thermal runaway releasing excessive heat,flammable and toxic gas emissions and eventually accompanied by dissembling/explosion and fire. READ MORE
