  1. 1. Pulse Charging of Li-ion Batteries for Enhanced Life Performance

    University essay from KTH/Kemiteknik

    Author : Josefin Strandberg; [2023]
    Keywords : Li-ion battery; Pulse charging; Cyclic aging; Capacity fade; Internal resistance; Battery impedance; Litiumjonbatteri; Pulsad laddning; Cyklisk åldring; Kapacitetsminskning; Inre resistans; Batteriimpedans;

    Abstract : Det överhängande behovet av att minska utsläppen av växthusgaser för att uppfylla Parisavtalet har väckt ett ökat intresse för elektrifiering som en strategi för att mildra klimatförändringarna. Litiumjonbatterier spelar en central roll vid elektrifiering och har framträtt som det primära alternativet för batteridrivna elfordon. READ MORE

    Abstract : The rate of degradation of a lithium-ion battery depends on its use i.e. how it is charged and discharged. Physics-based models are used to represent the processes inside a cell as well as the degradation mechanisms. READ MORE

  4. 3. Monitoring of crack growth and crack mouth opening displacement in compact tension specimens at high temperatures : Development and implementation of the Direct Current Potential Drop (DCPD) method

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Philip Malmqvist; [2016]
    Keywords : DCPD; Crack Growth; Compact Tension Testing; CMOD;

    Abstract : The mechanical engineering department at the University of Idaho is conducting a project with the purpose of developing a complete system for investigating creep-, creep-fatigue- and fatigue properties of metallic materials at elevated temperatures up to 650 ˚C with Compact Tension (CT) specimens. Considerable efforts have been made to study and understand these phenomena, although numerous problems still exist. READ MORE

  5. 4. Scanning Tunneling Microscopy and Spectroscopy of the GaSb(111)B surface

    University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Author : Pontus Littow; [2016]
    Keywords : Physics and Astronomy;

    Abstract : In this thesis the III-V semiconductor material GaSb (111) was studied using Scanning Tunneling Microscopy and Scanning Tunneling Spectroscopy. To characterize the surfaces of semiconductors has become more relevant in today society. When semiconductors become so small that they are in the micro scale the surface must be taken into consideration. READ MORE
