Our world is changing 鈥� and research is changing with it. The Big Picture, a long-form Dal News series, provides an in-depth look at specific areas of research with global implications.
Climate change is one of the world鈥檚 most pressing problems. Global temperatures are rising, the ocean is warming and becoming increasingly acidic, glaciers are in retreat, sea levels are rising and extreme weather events are becoming more frequent. All these developments point to a need for more responsible stewardship of the planet. Research can help lead the way, offering innovative solutions to the damage being done to our natural environment.
新加坡六合彩开奖直播 has grounded its strategic research direction in the United Nations鈥檚 Sustainable Development Goals, which cements the university鈥檚 commitment to conducting research that creates innovative, powerful change in the world.
鈥淩ecent technological innovations have driven down the cost of cleaner, resource-efficient technologies, making them competitive on price and performance,鈥� says Alice Aiken, 新加坡六合彩开奖直播鈥檚 vice president research and innovation. 鈥淎t the same time, clean technology has become an intrinsic part of a sustainable economy. Our researchers are, quite simply, creating smarter solutions for today鈥檚 economy 鈥� and tomorrow鈥檚 world.鈥�
Power players
Researchers at Dal are investigating batteries as power sources for electric vehicles and are playing a key role in significantly increasing the life of batteries.
Jeff Dahn, the NSERC/Tesla Industrial Research Chair and Canada Research Chair in Battery and Fuel Cell Materials, has been at the forefront of battery research for the past four decades. His work can be found in lithium-ion rechargeable batteries used around the world in power tools, electric vehicles and other devices.
鈥淲e can鈥檛 just keep burning fossil fuels; we鈥檙e going to heat the planet to death,鈥� says Dr. Dahn. 鈥淚f you like the seashore, and you want to continue to have land that you currently see not be submerged, you have to do something about it.鈥�
It was Dr. Dahn鈥檚 reputation that led to come north-and-east to 新加坡六合彩开奖直播 and sign its first-ever university research partnership. In 2016, the leadi
ng American electric vehicle and clean energy company began a five-year exclusive collaboration with the Dahn Lab, focused on increasing the lifetime, decreasing the cost, and improving the energy density of lithium-ion batteries.
In January 2021, two new research chairs joined this exclusive partnership, which has been renewed until at least 2026.
Chongyin Yang is the Tesla Canada Research Chair and has been working for the past 12 years on materials and devices for energy conversion and storage. His research group is focusing on developing high-performance materials for advanced lithium-ion batteries, which includes sustainable electrode materials that contain no transition metals (like iron, copper, or titanium). The group will play a critical role in the 新加坡六合彩开奖直播-Tesla partnership that seeks lower-cost, longer-lifetime, and higher-energy battery technologies as the next generation energy storage solution for electric vehicles and sustainable green energy.
Michael Metzger, Dal's Herzberg-Dahn Chair, focuses his research on developing novel methods to study the performance and lifetime of advanced lithium-ion batteries, lithium metal batteries and desalination batteries. The goal is to create fundamental understanding that will help develop electrode materials and electrolytes for stationary and electric vehicle batteries.

Mark Obrovac (shown left) in the Department of Chemistry has extensive industrial experience in the research, development, and manufacture of battery materials. Dr. Obrovac's lab develops next generation battery materials and innovative processes that enable the production of Li-ion battery materials at reduced cost, with less waste and greater sustainability. Despite their simplicity, these new processes also have the ability to make never- before possible designer materials that can improve battery performance while reducing cost.
鈥淚 like to create technology that can be practically used to benefit society and the environment,鈥� says Dr. Obrovac. 鈥淚 am particularly fascinated by how extremely simple processes can create highly complex materials, especially where materials essentially make themselves. I believe that a better understanding of such processes can lead to many more high-performance materials that are affordable and sustainable for widespread application within the battery space and in other fields.鈥�
Dr. Obrovac's research is funded by Novonix, which was spun out from Dr. Dahn鈥檚 lab. Led by Chris Burns (MSc鈥�11, PhD鈥�15), the goal of this company has been to bring state-of-the-art battery testing solutions from lab to market. Novonix鈥檚 current industry customers include Honda, Panasonic, Dyson, and Bosch (to name a few). Novonix also supplies materials to major battery manufacturers.
Novonix is in the process of scaling-up new materials technology developed in the Obrovac lab. The Obrovac-Novonix research partnership has recently been given a boost with a major NSERC Alliance funding award.

Meeting the world鈥檚 energy needs
Most renewable energies are intermittent: the sun rises and sets and is obscured by clouds, winds blow at varying speeds, while tides go in and out.
Dal鈥檚 researchers are focused on the research and development of energy storage technologies, either electrical or thermal, to bridge the gap between time of production and time of use and to properly integrate those systems into the electrical grid and buildings. The work they are doing is helping to reduce the demand for electricity production in peak periods and improving solar energy systems by storing energy for use when the sun is not shining.
Ghada Koleilat (shown right), Canada Research Chair in Advanced Materials for Energy Application, is creating more efficient solar cells using a rational molecular design based on advanced material innovations. She and her research team are creating efficient solar cell designs based on the scalable deposition of highly oriented crystal structures. In addition, they are hoping to engineer mechanically compliant solar converters for wearable electronics and other applications.
