1. 6. Open-Circuit-Voltage hysteresis measurement and modelling of LiFePO4 Batteries : Master Thesis Report - 2023

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Guillaume Larrat; [2023]
   Keywords : Open-Circuit-Voltage OCV Hysteresis - Voltage relaxation - Galvanostatic Intermittent Titration Technique GITT - Hysteresis modelling; Öppenkretsspännings OCV hysteres - Spänningsrelaxation - Galvanostatisk intermittent titreringsteknik GITT - Hysteresmodellering;

   Abstract : In a context of an expected increasing use of Lithium-ion batteries in the transportation sector, Volvo AB is developing its own solutions for large electric vehicles. It is then beneficial to reduce the costs, the energy demand and the raw materials demand by improving the battery systems’ performances. READ MORE

3. 7. 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

4. 8. Investigation of Ion Extraction Anomalies at TwinEBIS

   University essay from Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

   Author : Niek van Woudenberg; [2023]
   Keywords : CERN; ISOLDE; Ion Source; EBIS; REXEBIS; TwinEBIS; Ion losses; Charge Breeding; Ion Extraction; CST Studio Suite; Physics and Astronomy;

   Abstract : The electron beam ion source REXEBIS at CERN-ISOLDE delivers highly-charged ra- dioactive ions for post-acceleration in the HIE-ISOLDE LINAC. Research and develop- ment of components for electron beam ion sources is carried out at the TwinEBIS test stand, currently equipped with a Brillouin electron gun called MEDeGUN. READ MORE

5. 9. Fast deep discharging using a controllable load as pretreatment for EV battery recycling : A study on efficacy, speed, and safety

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Lucas Van Genechten; [2023]
   Keywords : Recycling; lithium-ion battery; deep discharging; external short-circuit; internal pressure; thermal stability; Electrochemical impedance spectroscopy; Återvinning; litiumjonbatteri; djupurladdning; extern kortslutning; internt tryck; termisk stabilitet; electrochemical impedance spectroscopy;

   Abstract : In response to the present and projected growth of the EV industry, the development of a large-scale, reliable and efficient lithium-ion battery recycling sector is vital to ensure circularity of the embedded valuable metals and ensure overall sustainability of the technology. One of the main recycling procedures under development is based on hydrometallurgy. READ MORE

6. 10. Automatic Interpretation of Ion Beam Measurements of Walls in Fusion Machines

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Daniel Lundberg; Ludvig Johansson; [2023]
   Keywords : ;

   Abstract : The purpose of this study is to investigate whether it is possible to automatically interpret theresults of Time-of-flight Elastic Recoil Detection Analysis (ToF-ERDA). And if so, find out if the automaticinterpretation is quicker and/or more accurate than the current approach that consists of manualanalysis. READ MORE
