Forskningsöversikt (refereegranskat)abstract
- This roadmap presents the transformational research ideas proposed by "BATTERY 2030+," the European large-scale research initiative for future battery chemistries. A "chemistry-neutral" roadmap to advance battery research, particularly at low technology readiness levels, is outlined, with a time horizon of more than ten years. The roadmap is centered around six themes: 1) accelerated materials discovery platform, 2) battery interface genome, with the integration of smart functionalities such as 3) sensing and 4) self-healing processes. Beyond chemistry related aspects also include crosscutting research regarding 5) manufacturability and 6) recyclability. This roadmap should be seen as an enabling complement to the global battery roadmaps which focus on expected ultrahigh battery performance, especially for the future of transport. Batteries are used in many applications and are considered to be one technology necessary to reach the climate goals. Currently the market is dominated by lithium-ion batteries, which perform well, but despite new generations coming in the near future, they will soon approach their performance limits. Without major breakthroughs, battery performance and production requirements will not be sufficient to enable the building of a climate-neutral society. Through this "chemistry neutral" approach a generic toolbox transforming the way batteries are developed, designed and manufactured, will be created.

Battery 2030+ Roadmap
- 2020

Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Climate change is the biggest challenge facing the world today. Europe is committed to achieving a climate-neutral society by 2050, as stated in the European Green Deal.1 The transition towards a climate-neutral Europe requires fundamental changes in the way we generate and use energy. If batteries can be made simultaneously more sustainable, safe, ultrahigh performing, and affordable, they will be true enablers, “accelerating the shift towards sustainable and smart mobility; supplying clean, affordable and secure energy; and mobilizing industry for a clean and circular economy” - all of which are important elements of the UN Sustainable Development Goals.In other words, batteries are a key technology for battling carbon dioxide emissions from the transport, power, and industry sectors. However, to reach our sustainability goals, batteries must exhibit ultra-high performance beyond their capabilities today. Ultra-high performance includes energy and power performance approaching theoretical limits, outstanding lifetime and reliability, and enhanced safety and environmental sustainability. Furthermore, to be commercially successful, these batteries must support scalability that enables cost-effective large-scale production.BATTERY 2030+, is the large-scale, long-term European research initiative with the vision of inventing the sustainable batteries of the future, to enable Europe to reach the goals envisaged in the European Green Deal. BATTERY 2030+ is at the heart of a green and connected society.BATTERY 2030+ will contribute to create a vibrant battery research and development (R&D) community in Europe, focusing on long-term research that will continuously feed new knowledge and technologies throughout the value chain, resulting in new products and innovations. In addition, the initiative will attract talent from across Europe and contribute to ensure access to competences needed for ongoing societal transformation.The BATTERY 2030+ aims are:• to invent ultra-high performance batteries that are safe, affordable, and sustainable, witha long lifetime.• to provide new tools and breakthrough technologies to the European battery industrythroughout the value chain.• to enable long-term European leadership in both existing markets (e.g., transport andstationary storage) and future emerging sectors (e.g., robotics, aerospace, medical devices, and Internet of things)With this roadmap, BATTERY 2030+ advocates research directions based on a chemistry-neutral approach that will allow Europe to reach or even surpass its ambitious battery performance targets set in the European Strategic Energy Technology Plan (SET-Plan)3 and foster innovation throughout the battery value chain.

Automatic Cable Harness Layout Routing in a Customizable 3D Environment
- 2024
-
Ingår i: CAD Computer Aided Design. - 0010-4485. ; 169
-
Tidskriftsartikel (refereegranskat)abstract
- Designing cable harnesses can be time-consuming and complex due to many design and manufacturing aspects and rules. Automating the design process can help to fulfil these rules, speed up the process, and optimize the design. To accommodate this, we formulate a harness routing optimization problem to minimize cable lengths, maximize bundling by rewarding shared paths, and optimize the cables’ spatial location with respect to case-specific information of the routing environment, e.g., zones to avoid. A deterministic and computationally effective cable harness routing algorithm has been developed to solve the routing problem and is used to generate a set of cable harness topology candidates and approximate the Pareto front. Our approach was tested against a stochastic and an exact solver and our routing algorithm generated objective function values better than the stochastic approach and close to the exact solver. Our algorithm was able to find solutions, some of them being proven to be near-optimal, for three industrial-sized 3D cases within reasonable time (in magnitude of seconds to minutes) and the computation times were comparable to those of the stochastic approach.

An Investigation of the Relationship between Personality, Cognitive Ability, and Work Engagement in Intellectually Gifted Individuals

Tidskriftsartikel (refereegranskat)abstract
- Do personality traits in highly intelligent individuals relate to their work engagement? Seemingly little is known about the relationship between personality and work engagement for gifted individuals. In what may be the first study to do so, a Swedish Mensa sample (n = 353) was explored with a two-part aim: to assess psychometric personality properties and to investigate the relationship between personality traits (Mini-IPIP6) and work engagement (UWES-9). The results of the Mensa members and the Mturk sample (1.4 SD lower in cognitive ability based on ICAR-16) were compared using a confirmatory factor analysis (CFA) and a regression. The findings indicated that the Mensa sample had higher openness (d =.50) and honesty-humility (d =.65) and that personality traits were similarly related to work engagement in both groups, with the exception that neither openness nor honesty-humility were related to work engagement in the Mensa sample. The characteristics of intellectually gifted individuals are further discussed.

Lithostratigraphy and alteration at the Rävliden North VMS deposit, Skellefte district, Sweden
- 2024
-
Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Technological and societal developments in the past century have greatly increased our society’s demand for metals, many which occur in polymetallic ores mined in the Skellefte district, northern Sweden. Near-surface deposits are becoming depleted and as such targeting of deep deposits is needed, which places special demand on effective management, processing and interpretation of geological data obtained from exploration drill holes. New exploration tools and software solutions utilizing machine learning to assist data analysis are becoming increasingly important. However, to get the most of these new tools, a solid geological understanding of prospective areas must first be established.This thesis uses the Rävliden North Zn-Pb-Ag-Cu volcanic massive sulphide (VMS) deposit as a study location to understand its lithostratigraphy and enveloping alteration. The Skellefte district VMS deposits are mainly located at the lithostratigraphic contact between the metavolcanic 1.89 – 1.88 Ga Skellefte group (SG) and the stratigraphically overlying metasiliciclastic 1.89 – 1.87 Ga Vargfors group (VG) rocks. The VMS deposits are commonly enveloped by a zoned alteration with variable alteration intensity and mineral assemblages of quartz, sericite, chlorite and talc at different distance to mineralisation. Sixteen lithofacies and eight precursors can be defined in the Rävliden North host succession, where the SG dominantly contains coherent and volcaniclastic facies of rhyolite, dacite and andesite. The VG contains graphitic phyllite interbedded with polymict breccia-conglomerates, andesitic turbidites and mafic mass-flow deposits. Immobile element lithogeochemistry reveals four rhyolitic (Rhy I – IV), two dacitic (Dac I and II), an andesitic (And I), and a basaltic (Bas I) precursors. The VMS deposits are hosted by graphitic phyllite Tr-rich calc-silicate rock, and a Chl>Ser±Tlc±Qz-altered rock in the contact between the SG and VG. Four alteration types are recognised and spatially associated to mass changes of mobile elements. The Tr-rich calc-silicate and calcitic rocks are related to gains in CaO and occur proximal to mineralisation. Chlorite>Ser±Tlc±Qz alteration is related to gains in MgO and FeO and also occur proximal to mineralisation. The choice of least-altered volcanic rocks, needed for modelling fractionation, is found to have effect on the resulting mass-balance calculation; however, qualitative recognition of mass changes related to the ore-hosting alteration types is still possible. The uncertainty ranges of mass changes are determined to be ±0.5 wt.% for MgO, FeO and CaO.This thesis demonstrates that geological understanding and quantification of error and uncertainty in mass balance calculations are necessary prerequisites to advanced exploration techniques.
