Commercialization of used vehicle batteries - Battery 2nd life business opportunities for the heavy duty vehicle sector
The purpose of this thesis was to determine how a heavy duty vehicle manufacturer can create an economical viable business model for used batteries from electric buses and trucks. Heavy duty vehicles are responsible for 30% of on-road CO2 emissions in the European Union, but could be decreased if this sector would be electrified. One major barrier for this transition is the large cost for the batt
How overdischarge destabilizes NCM cathodes : A combined study on structural evolution and chemical states
Overdischarge poses severe challenges to the structural integrity and electrochemical performance of layered LiNixCoyMn1-x-yO2 (NCM) cathodes in lithium-ion batteries, yet the underlying degradation mechanisms remain insufficiently understood. Through a combined experimental and theoretical approach, this study systematically investigates how overdischarge destabilizes NCM cathodes with varying tr
Energy Stored by Radiating Systems
Though commonly used to calculate Q-factor and fractional bandwidth, the energy stored by radiating systems (antennas) is a subtle and challenging concept that has perplexed researchers for over half a century. Here, the obstacles in defining and calculating stored energy in general electromagnetic systems are presented from first principles as well as using demonstrative examples from electrostat

LED Lighting with a Photovoltaic System and Energy Storage for a Jogging Track in the Countryside
Our research aims to develop an intelligent control system for optimizing the operation of lighting systems for a jogging track in the countryside by using adaptive control methods, and optimization of built-in lighting control. Through this, lighting systems will be optimized, energy consumption will be minimized and the lighting system will be adapted to be able to handle a larger amount of loca
Helical tomotherapy for total marrow and total skin irradiation : Optimisation, verification, and clinical results
In modern cancer therapy, radiotherapy (RT) is a vital part of most treatments. Most RT treatments in Sweden are performed using intensity-modulated radiotherapy (IMRT) with fixed or dynamic arc delivery. The dose gradients outside the target are steep, the margins are small, and the treatment delivery is complicated. Complicated treatments increase the requirement for control of the uncertaintiesIn modern cancer therapy, radiotherapy (RT) is a vital part of most treatments.

Energy balance closure, water balance, carbon exchange, and water use efficiency : observed and modeled outcomes for a managed, hemiboreal forest in Southern Sweden
The claims for the potential of boreal and sub-boreal forests to combat negative effects of climate change have been substantial with over half of Earth’s primary forests found within boreal and temperate regions of the Northern Hemisphere. Given the likely occurrence of more extreme climate events in the future, ascertaining a better understanding of how climate effects, such as profound fluctu

LTH profilområde: Energiomställningen
Det finns lösningar för att göra samhället oberoende av fossil energi. Men för att kunna tillämpa dem behövs tvärvetenskaplig forskning och samverkan inom områden som hållbara bränslen och termisk energi, systemstudier, samt elektrifiering och energilagring – där profilområdet har spetskunskap.
AdTherM: Advanced Computing for Sustainable Thermal Management in Industry
Kompetenscentret AdTherM inriktar sig på analyser av termiska processer i industriella tillämpningar, inklusive termo- och elektrokemisk energiomvandling. De flesta utmaningar för industrin inom detta område är generiska och baseras på samma fysiska mekanismer. För att utveckla detta forskningsfält måste både experiment och modeller förbättras och samordnas. AdTherM är en plattform som är centreraAdTherM targets analyses of thermal processes in industrial applications, including thermo- and electrochemical energy conversion activities. Most challenges for the industry in this area are generic and based on the same physical mechanisms. To develop this field, both experiments and models need to be improved and coordinated. AdTherM is a platform centered around the models and methods used t
Wavy Surface Cathode Gas Flow Channel Effects on Transport Processes in a Proton Exchange Membrane Fuel Cell
The flow field design of current collectors is a significant issue, which greatly affects the mass transport processes of reactants/products inside fuel cells. Especially for proton exchange membrane (PEM) fuel cells, an appropriate flow field design is very important due to the water balance problem. In this paper, a wavy surface is employed at the cathode flow channel to improve the oxygen mass
Järnväg och kollektivtrafik
Vi studerar järnvägen ur ett antal olika perspektiv, med fokus på att höja dess kapacitet och punktlighet. Gruppens utgångspunkt är att klimatförändringar vår generations stora utmaning, och transportsektorn står för ungefär en tredjedel av utsläppen. Järnvägen är ett grönt och kapacitetsstarkt transportmedel som har stor potential att bidra positivt i omställningen till ett fossilfritt och energiWe study the railway from several different perspectives, with a focus on increasing its capacity and punctuality. The group's starting point is that climate change is our generation's major challenge, and the transport sector accounts for approximately one third of emissions. The railway is a green and high-capacity means of transport that has great potential to make a positive contribution to th
Perceived research needs for Battery and Hydrogen Safety : A Nordic Perspective
Changes in the energy landscape relating both to the ambitions of a green energy transformation as well as increasing global security concerns, have led to increased attention to new energy carriers. These can serve the role of allowing for the electrification of transport and decarbonization of industries as well as to reduce the effects of variation in many sustainable energy sources such as winChanges in the energy landscape relating both to the ambitions of a green energy transformation as well as increasing global security concerns, have led to increased attention to new energy carriers.
