1. 1. Optimisation of a Powder Dosing Equipment

   Master-uppsats, KTH/Kemiteknik

   Författare :Andrea Codo Morales; [2023]
   Nyckelord :mixing; slurry; production; cycles; equipment; blandning; slurry; produktion; cykler; utrustning;

   Sammanfattning : Klimatförändringar är en av de viktigaste problemen som påverkar framtida generationer. För att bekämpa detta införlivar Northvolt hållbara metoder genom hela batteriproduktionsprocessen. Ett avgörande steg i elektrodtillverkningen är slurryblandningen, vilket innebär att man kombinerar flera pulver inklusive det aktiva materialet. LÄS MER

3. 2. Design of a vacuum chamber for cathode testing and low power Hall Effect Thrusters : Collaborative project with OHB Sweden AB

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Andrea Martinez Sanz; [2023]
   Nyckelord :Vacuum chamber; adaptability; hollow cathode test; fluid ground support equipment; low power Hall Effect Thrusters test; Vakuumkammare; anpassningsförmåga; ihålig katod testa; flytande markstödutrustning; låg effekt Hall Effect Thrusters testa;

   Sammanfattning : Testing of hardware to be used in space sometimes involves using vacuum chambers. The need to test hollow cathodes, used as neutralizers for some Electric Propulsion Thrusters, and low power Hall Effect Thrusters at OHB Sweden requires a vacuum chamber to be upgraded. LÄS MER

4. 3. Application of electrodes with redox mechanisms for the desalination of water

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Pablo Moreno Cerezo; [2023]
   Nyckelord :Activated Carbon Cloth ACC ; Capacitive Deionization CDI ; Cyclic Voltammetry CV ; Electrochemistry; Polyaniline PANI ; Prussian Blue PB and Redox Reactions; Aktivt koltyg ACC ; Kapacitiv avjonisering CDI ; Cyklisk voltammetri CV ; Elektrokemi; Polyanilin PANI ; Preussisk blå PB och Redoxreaktioner;

   Sammanfattning : Capacitive deionization is a promising technology for purification and desalination of brackish water with great advantages over current technologies due to its low operating cost and high-water recovery ratio. Most of the system studied relies on the adsorption/desorption capacity of activated carbon electrodes due to its high surface area. LÄS MER

5. 4. Numerical modeling of airflow on the cathode-side of a bipolar flow plate : How the formed geometry affects the pressure drop and flow distribution in a hydrogen fuel cell

   Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

   Författare :Olivia Johansson; [2023]
   Nyckelord :Performance; Cross-sectional geometry; Computational fluid dynamics;

   Sammanfattning : Climate change and rising temperatures is a well-known problem. To tackle global warming a transition from fossil fuels to renewable and reliable energy sources is necessary. Hydrogen, in fuel cells, is proposed to replace diesel and gasoline in the transport sector. LÄS MER

7. 5. Battery Storage as Grid Reinforcement for Peak Power Demands

   Master-uppsats, Linköpings universitet/Energisystem

   Författare :Jesper Hilleberg; [2023]
   Nyckelord :Battery Storage; Battery Energy Storage System; Grid Reinforcement; Flexibility; Lithium-ion battery; li-ion battery; Large Scale Grid Storage; BESS; Energy Storage; Peak Power Demand; Batterilagring; Batterilagringsystem; Nätförstärkning; Nätförstärkningsåtgärd; toppeffektlaster; Flexibilitet; Flexibilitetslösning; litiumjonbatteri; li-ion batteri; BESS; energilagring;

   Sammanfattning : An increased amount of intermittent electricity production, more electric vehicles (EV), and an overall electrification of society may all cause a higher variability between the balance of supply and demand on the electric grid. Battery storage has been identified as a solution to the emerging problem asit can be charged during hours of low power demand and then discharged to help meet the power demand during peak loads.
