1. 1. State of charge and heat impact on Li-ion batteries during calendar aging

   University essay from Uppsala universitet/Signaler och system

   Author : Martin Jonsson; Tobias Karlsson; [2023]
   Keywords : State of charge; SoC; calendar aging; heat impact; Li-ion;

   Abstract : Rechargeable batteries that are powering our everyday electronics go through their lifetime with countless charge/discharge cycles, after a few years the capacity has dropped noticeably. But how about batteries that are working as a back-up power system for when connection to the AC mains is not possible, they might only perform a handful of cycles but does this mean they last forever? On behalf of Getinge AB, this bachelor thesis aims to explore the subject named as ‘calendar aging’. READ MORE

3. 2. Electrochemical Characterisation of LiFePO4-Coated Carbon Fibres: A Comparative Electrochemical Analysis of Three Coating Methods

   University essay from KTH/Tillämpad elektrokemi

   Author : Julia Szecsödy; [2023]
   Keywords : Structural battery composite; Carbon fibres; Lithium-ion battery; Electrophoretic deposition; Spray coating; Powder impregnation; Strukturella batteri kompositer; Kolfiber; Litiumjon batteri; Elektroforetisk beläggning; Sprutbeläggning; Pulverimpregnering;

   Abstract : Kolfiber CF kan användas som positiv elektrod i strukturella batterier om de beläggs med ett aktivt material, såsom litiumjärnfosfat LFP. Fördelen med att använda kolfibrer som elektroder är att de samtidigt kan bära mekanisk belastning och lagra elektrisk energi. Det finns flera tekniker för att belägga kolfibrerna. READ MORE

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

   Author : Diana Cristina Culincu; [2023]
   Keywords : Augmented Reality; Electric Vehicle Batteries; Lithium-Ion Batteries; Battery Dismantling; Battery Disassembly; Battery Recycling; Photogrammetry; 3D modelling; 3D Reconstruction; Vuforia; Unity; Blender; Figma; Polycam; Sustainability; Förstärkt verklighet; Batterier för elektriska fordon; Litiumjonbatterier; Batteriavmontering; Batteriuppdelning; Batteriåtervinning; Fotogrammetri; 3Dmodellering; 3D-rekonstruktion; Vuforia; Unity; Blender; Figma; Polycam; Hållbarhet;

   Abstract : The increasing adoption of electric vehicles (EVs) brings forth the challenge of effectively managing the second-life and end-of-life cycles for lithium-ion batteries. Augmented Reality (AR) offers a promising solution to sustainably and efficiently dismantle these batteries. READ MORE

5. 4. Development of a High Current Charger for Small Electric Boat Commuting

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

   Author : Axel Back Enoksson; Axel Boström; [2023]
   Keywords : ;

   Abstract : Electrification of the transport system is an important societal project which we are currentlyundergoing. With improvements in battery technology it is now possible to construct quite powerfulpersonal vehicles to replace combustion engines in not only cars but also motorcycles and boats. READ MORE

6. 5. Electrochemical Behavior of the High Entropy Oxide (Mg,Co,Ni,Zn)1-xLixO (x=0,35)

   University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Author : Rasmus Sandström Kinnane; [2022]
   Keywords : high entropy oxides; lithium-ion battery; x-ray diffraction; scanning electron microscopy; cyclic voltammetry;

   Abstract : Today's society is currently developing lithium-ion batteries to eventually replace the use of fossil fuels. High entropy oxides is a new type of material to use as an anode in the lithium-ion battery. These high entropy oxides may consist of a few different transition metals including lithium and oxygen.
