Title: Thermal Management of Automotive Lithium-Ion Batteries

 

Abstract: Advanced Li-ion battery technology is presently receiving huge attention worldwide for applications to electric vehicles and hybrid electric vehicles that aim to significantly boost fuel efficiency and reduce carbon emission. In this revived pursuit of vehicle electrification, grand challenges lie in cycle life, cost and highly dynamic operation requirements under harsh ambient temperatures of automotive Li-ion batteries. Heat generation and thermal transport plays major roles in understanding and solving these challenges. This talk will unravel critical thermal phenomena involved in automotive Li-ion batteries and elucidate how the thermal phenomena impact degradation processes at the nanoscale interface between electrode and electrolyte as well as interact with electrochemical and mass diffusion processes occurring at a myriad of length scales. Specific problems will be discussed of: 1) Li plating in the carbon anode under high-rate charging and subzero temperatures, 2) metal ion dissolution from cathode materials and subsequent migration into the anode to catalyze solid-electrolyte interphase (SEI) formation at elevated temperatures, and 3) thermal runaway and explosion. Needs and practice of thermal management will be highlighted. Current efforts to link thermal and electrochemical phenomena via experimental diagnostics and fundamental modeling will be shared [1-7].

Title: Effect of Impurities in Coal-Syngas on the Performance of Solid Oxide Fuel Cells

 

Abstract: High temperature solid oxide fuel cells (SOFC) are amenable for utilization of various fuels including synthetic gas produced from coal by gasification. However, coal gas inevitably contains many impurities, such as species of Sulfur, Arsenic, Phosphorus, etc. which can be detrimental to the operation of the cell even when only trace amounts of are present. Experimental and numerical results will be presented from an ongoing study aiming at understanding the degradation mechanisms of various contaminants in a typical SOFC. Experiments show that a typical SOFC could loose up to 80% of its power within several hundred minutes when exposed to 5-10 ppm of PH3. Detailed measurements have revealed that PH3 reacts with Ni to form secondary phase hence leading to loss of active sites in the anode. Modeling results indicates that the severest degradation occurs when PH3 reaches the anode–electrolyte inter-phase and starts to deactivate electrochemical reactions.

Title: How to Develop a Sustainable Fossil Fuel Free Country

 

Abstract: Starting from the national energy balance of today actions are discussed on how to drive towards a fossil fuel free society. The available renewable energy resources are identified and how these can be utilised is discussed. This includes both investigation of the possibility to use crops with a higher yield from an energy point of view, as well as to localise spots where the wind is high enough for wind power plants. Hydro power already gives 70 TWhel/y in Sweden, but new resources and enhancements of the existing are reviewed. The possibility to use solar power in combination with other resources for both heat and power is investigated, where TPV, Thermo Photo Voltaic is as interesting as PV-technique in a country with little sun-shine winter time. The use of waste like household waste and crops like straw for both poly-generation and bio-gas production are described. Actions to save energy in industry are discussed for process industries and manufacturing industries, as well as for offices and households. LED lamps instead of conventional lamps have a high potential which is also relatively easy to implement. Next step is to make a scenario for how to reach a consumption that is less the available resources, and here different consumption patterns as well as ways to change these are handled. Different political actions, like information, taxes and incentives like subsidies are discussed. Introduction of new price models for energy and power is another tool that is being evaluated. By implementing these we can avoid the need for building new peak power capacity to compensate for the intermittent production from sources like wind and sun power. Energy efficient buildings and smart homes can give major impact on one of the major needs as heating is of major importance winter time, and cooling summer time. The pros and cons for different solutions are discussed.

Title: Redox Flow Battery for Energy Storage

 

Abstract: Energy storage technologies have long been recognized to have significant potential to promote renewable energy (such as solar and wind etc.) and smart grid program. The use of energy storage in smart grid for load leveling and peak shaving can improve the utilization of generation, transmission, and distribution assets, and can allow utilities to defer investment in additional capacity. Energy storage can also be of use in dynamic operation of the grid when renewable energy involved, providing frequency regulation and spinning reserve.

 

Compared with other energy storage technologies, redox flow battery (RFB) have some competitive advantages – long life, high energy convention efficiency, active thermal management, and independence of energy and power ratings – make them particularly well-suited for relatively large-scale utility applications. For more than 20 years’ research, there are several flow battery types, including Fe-Cr, zinc-chlorine, zinc-bromine (Zn-Br2), polysulfide-bromide (PSB) and vanadium redox flow battery (VRB). Of these, VRB have special advantages in design simplicity and ease operation because the same electrolyte is used for both the positive and the negative side, make VRB becoming the focus of R&D of RFB. Due to its outstanding advantages of VRB, it is well suited for a variety of applications, firming the intermittent renewable energy output power, peak shaving to the grid, effective power in the remote area, energy storage for electricity vehicle rapid charge station, back-up power for substation and telecommunication sites.

 

So far, there are some research organizations and corporations focusing on the R&D of VRB, including University of New South Wales (UNSW) and V-fuel Ltd. in Australia, Sumitomo Electrc (SEI) in Japan, Dalian Institute of Chemical Physics (DICP) and Rongke Power Ltd. in China, Cellennium Company, Ltd. in Thailand. The demonstrated VRB system ranged from kW to MW of power and kWh to MWh of capacity, with the demonstrated fields in wind farm, solar power station, electricity vehicle charge station, remote telecommunication station and peak shaving for grid.

 

In this presentation, current progresses and issues, future development trend of RFB will be described in detail.

Title: Non-noble Metal Electrocatalysis: A sustainable solution for PEM Fuel Cells

Abstract: Electrocatalysts have large responsibility to both high cost and insufficient durability in today’s PEM fuel cell technology, hindering its commercialization. Developing new electrocatalysts is the priority research work across the fuel cell community. With respect to high costly Pt-based electrocatalysts, non-noble metal catalysts are considered the most cost-effective and feasible way to permanently resolve the cost issue for PEM fuel cell commercialization. Although the activity and stability are still large challenges for state-of-the-art non-noble metal catalysts in practical PEM fuel cell applications, great progress has been made in recent years. In this presentation, we review the historical and current R&D status of non-noble metal catalysts towards the ORR for PEM fuel cells, with focus on analyzing and discussing the challenges and perspectives of non-noble metal catalysts development. We summarized three ways to approach the success of non-noble metal catalysts: (1) Understanding the ORR mechanism and active sites to know how to achieve high intrinsic activity; (2) Exploring new synthesis techniques to control catalyst structure for high active site density; and (3) Optimizing catalyst layer to achieve high performance MEAs. Based on our own work on heat-treated transition metal (Fe and Co) macrocycles, some detailed research results and future directions towards non-noble metal catalyst development will be disclosed.

Title: Energy Sustainability: A Key to Addressing Environmental, Economic and Societal Challenges

 

Abstract: Sustainability is a critically important goal for human activity and development. Energy sustainability is of great importance to any plans for overall sustainability given the pervasiveness of energy use, its importance in economic development and living standards, and the significant impacts that energy processes and systems have on the environment. Many factors that need to be considered and appropriately addressed in moving towards energy sustainability are examined in this presentation. These include appropriate selection of energy resources bearing in mind sustainability criteria, facilitation of the use of sustainable energy resources, enhancement of the efficiency of energy-related processes, and a holistic adoption of environmental stewardship in energy activities. In addition, other key sustainability measures are addressed, such as economics, equity, land use, lifestyle, sociopolitical factors and population.

 

The objective is to help identify sustainable energy solutions and ways to overcome the barriers, so that sustainable energy can better contribute to sustainable development. The challenges and opportunities of sustainable energy are global in extent, and greatly affect developed and developing countries alike. But the objective of sustainable energy is difficult to attain, due to economic and other pressures, and much effort is needed to overcome such barriers. Since climate change poses one of the greatest challenges facing humanity and is greatly affected by energy utilization, it will receive special attention in the presentation. To avoid climate change and its potential disruptive impacts, energy use need to become more sustainable in all respects, including production, utilization, distribution, storage and waste disposal. Conclusions are provided related both to options and pathways for energy sustainability and to the broader ultimate objective of sustainability.

Title: Photovoltaic Energy Conversion: Future Directions and Role of the Research Community

 

Abstract: The global photovoltaics production has been steadily growing over the last two decades and the trend is expected to continue into the foreseeable future. The growth has also seen sharp increase in the manufacture of the base semiconductor material - silicon, for the PV market. Current industrial manufacturing processes are mainly dominated the traditional, time-tested technologies. On the other hand, new device and material concepts based on nano-technologies show tremendous promise in terms of performance of the PV devices. Most of these new concepts are at an early stage of research. Once these scientifically-unchallenged concepts are realized experimentally at a larger scale, and after their safety, reliability, manufacturability are proven, the new technologies are expected to make headway into the PV manufacturing in the medium-to-long term.
