She develops materials for electrochemical energy storage and conversion. Nazar demonstrated that interwoven composites could be used to improve the energy density of lithium–sulphur batteries. She was awarded the 2019 Chemical Institute of Canada Medal.

Early life and education

Nazar studied chemistry at the University of British Columbia, where she earned a bachelor's degree in 1978. [1] She was inspired to study chemistry after being inspired by her first year professor. [2] Her father had trained as a scientist and ran his own jewellery making business. [2] Nazar joined the University of Toronto for her graduate studies, and completed a PhD under the supervision of Geoffrey Ozin in 1984. After obtaining her degree, she worked as a postdoctoral researcher working with Allan Jacobson at Exxon Research and Engineering Company, [3] before joining the University of Waterloo in the late 1980s, when she became interested in electrochemistry and Inorganic chemistry. [2]

Research and career

Nazar works in materials chemistry at the University of Waterloo, where she designs energy storage devices and electrochemical systems. Her research group create new materials and nanostructures for lithium–sulfur batteries, including interwoven composites. She develops structural probes to understand how the morphology of materials that are capable of charge/ ionic redox processes impact their functions. These techniques include nuclear magnetic resonance (NMR), electrochemistry, AC Impedance Spectroscopy and X-ray diffraction measurements. [4] [5] Nazar was a founding member of the Waterloo Institute for Nanotechnology. [3] Nazar is recognised as being a "leading authority in advanced materials". [6] She was awarded a Canada Research Chair in 2004, which was renewed in 2008 and 2012. [7] [8] [9] In 2009 Nazar joined the California Institute of Technology as a More Distinguished Scholar. [3] [10] In 2013 she was awarded a $1.8 million fellowship from the National Research Council to investigate energy storage materials for automotive applications. [11]

Nazar is particularly interested in storage materials that go beyond lithium-ion batteries, sodium-ion batteries, zinc ion batteries and magnesium-ion batteries. [12] [13] [14] [15] Lithium-ion batteries are the battery of choice in hybrid electric vehicles, but concerns have arisen about the global supply of lithium. Her early work developed porous carbon architectures as frameworks for cathodes, enhancing their conductivity and discharge capacity. [16] She demonstrated that interwoven carbon composites could be used to improve the energy density of lithium–sulphur batteries. [4] She showed it was possible to create mesoporous carbon frameworks that constrain the grown of sulphur nanofillers, which improved energy storage and reversibility. [16]

Nazar calculated the low-cost lithium–sulphur batteries could take electric cars twice as far as current lithium-ion technologies. [2] Sulphur is an abundant material that can be used to replace cobalt oxide in lithium-ion batteries. [17] Unfortunately, sulphur can dissolve into the electrolyte solution, and be reduced by electrons to form polysulphides. [18] They are also susceptible to high internal resistance and capacity fading on cycling. [17] These challenges can be overcome by creating nanostructures in the electrodes. [17] Interwoven composites can also be made from manganese dioxide, which stabilise polysuplphides in lithium–sulphur batteries. [18] Manganese dioxide reduces sulphides via a surface-bound polythiosulphanates, and can withstand 2,000 discharge cycles without the loss of capacitance. [2] [18] [19] She has also developed lithium oxygen batteries, which are lightweight with high energy density. [20] [21] In lithium oxygen batteries, superoxide and peroxide can act to degrade the cells; limiting their lifetime. [21] If the electrolyte is replaced with a molten salt and the porous cathode with a bifunctional metal oxide, the peroxide does not form. [21] Nazar has worked on supercapacitors and polyanion materials. [22] [23]

She was made a Professor at the University of Waterloo in 2016 and holds a Tier 1 Canada Research Chair in Solid State Energy Materials. [24] Since 2014 Nazar has served on the board of directors of the International Meeting on Li-Batteries. [25] She serves on the editorial boards of the journals Angewandte Chemie, Energy & Environmental Science and the Journal of Materials Chemistry A. [26] [27]

<span class="mw-page-title-main">Lithium-ion battery</span> Type of rechargeable battery

A lithium-ion or Li-ion battery is a type of rechargeable battery that uses the reversible intercalation of Li+ ions into electronically conducting solids to store energy. In comparison with other commercial rechargeable batteries, Li-ion batteries are characterized by higher specific energy, higher energy density, higher energy efficiency, a longer cycle life, and a longer calendar life. Also noteworthy is a dramatic improvement in lithium-ion battery properties after their market introduction in 1991: over the following 30 years, their volumetric energy density increased threefold while their cost dropped tenfold. In late 2024 global demand passed 1 Terawatt-hour per year, while production capacity was more than twice that.

<span class="mw-page-title-main">Lithium metal battery</span> Non-rechargeable battery using lithium metal as anode

Lithium metal batteries are primary batteries that have metallic lithium as an anode. The name intentionally refers to the metal as to distinguish them from lithium-ion batteries, which use lithiated metal oxides as the cathode material. Although most lithium metal batteries are non-rechargeable, rechargeable lithium metal batteries are also under development. Since 2007, Dangerous Goods Regulations differentiate between lithium metal batteries and lithium-ion batteries.

<span class="mw-page-title-main">History of the battery</span>

Batteries provided the main source of electricity before the development of electric generators and electrical grids around the end of the 19th century. Successive improvements in battery technology facilitated major electrical advances, from early scientific studies to the rise of telegraphs and telephones, eventually leading to portable computers, mobile phones, electric cars, and many other electrical devices.

<span class="mw-page-title-main">Lithium-ion capacitor</span> Hybrid type of capacitor

A lithium-ion capacitor is a hybrid type of capacitor classified as a type of supercapacitor. It is called a hybrid because the anode is the same as those used in lithium-ion batteries and the cathode is the same as those used in supercapacitors. Activated carbon is typically used as the cathode. The anode of the LIC consists of carbon material which is often pre-doped with lithium ions. This pre-doping process lowers the potential of the anode and allows a relatively high output voltage compared to other supercapacitors.

<span class="mw-page-title-main">Lithium–sulfur battery</span> Type of rechargeable battery

The lithium–sulfur battery is a type of rechargeable battery. It is notable for its high specific energy. The low atomic weight of lithium and moderate atomic weight of sulfur means that Li–S batteries are relatively light. They were used on the longest and highest-altitude unmanned solar-powered aeroplane flight by Zephyr 6 in August 2008.

Michael Makepeace Thackeray is a South African chemist and battery materials researcher. He is mainly known for his work on electrochemically active cathode materials. In the mid-1980s he co-discovered the manganese oxide spinel family of cathodes for lithium ion batteries while working in the lab of John Goodenough at the University of Oxford. In 1998, while at Argonne National Laboratory, he led a team that first reported the NMC cathode technology. Patent protection around the concept and materials were first issued in 2005 to Argonne National Laboratory to a team with Thackeray, Khalil Amine, Jaekook Kim, and Christopher Johnson. The reported invention is now widely used in consumer electronics and electric vehicles.

A zinc-ion battery or Zn-ion battery (abbreviated as ZIB) uses zinc ions (Zn2+) as the charge carriers. Specifically, ZIBs utilize Zn metal as the anode, Zn-intercalating materials as the cathode, and a Zn-containing electrolyte. Generally, the term zinc-ion battery is reserved for rechargeable (secondary) batteries, which are sometimes also referred to as rechargeable zinc metal batteries (RZMB). Thus, ZIBs are different than non-rechargeable (primary) batteries which use zinc, such as alkaline or zinc–carbon batteries.
