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]

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.

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

The lithium iron phosphate battery or LFP battery is a type of lithium-ion battery using lithium iron phosphate as the cathode material, and a graphitic carbon electrode with a metallic backing as the anode. Because of their low cost, high safety, low toxicity, long cycle life and other factors, LFP batteries are finding a number of roles in vehicle use, utility-scale stationary applications, and backup power. LFP batteries are cobalt-free. As of September 2022, LFP type battery market share for EVs reached 31%, and of that, 68% were from EV makers Tesla and BYD alone. Chinese manufacturers currently hold a near monopoly of LFP battery type production. With patents having started to expire in 2022 and the increased demand for cheaper EV batteries, LFP type production is expected to rise further and surpass lithium nickel manganese cobalt oxides (NMC) type batteries in 2028.

<span class="mw-page-title-main">Nanobatteries</span> Type of battery

Nanobatteries are fabricated batteries employing technology at the nanoscale, particles that measure less than 100 nanometers or 10−7 meters. These batteries may be nano in size or may use nanotechnology in a macro scale battery. Nanoscale batteries can be combined to function as a macrobattery such as within a nanopore battery.

<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.

The lithium–air battery (Li–air) is a metal–air electrochemical cell or battery chemistry that uses oxidation of lithium at the anode and reduction of oxygen at the cathode to induce a current flow.

A potassium-ion battery or K-ion battery is a type of battery and analogue to lithium-ion batteries, using potassium ions for charge transfer instead of lithium ions.

A lithium ion manganese oxide battery (LMO) is a lithium-ion cell that uses manganese dioxide, MnO
2, as the cathode material. They function through the same intercalation/de-intercalation mechanism as other commercialized secondary battery technologies, such as LiCoO
2. Cathodes based on manganese-oxide components are earth-abundant, inexpensive, non-toxic, and provide better thermal stability.

Research in lithium-ion batteries has produced many proposed refinements of lithium-ion batteries. Areas of research interest have focused on improving energy density, safety, rate capability, cycle durability, flexibility, and reducing cost.

Lithium hybrid organic batteries are an energy storage device that combines lithium with an organic polymer. For example, polyaniline vanadium (V) oxide (PAni/V2O5) can be incorporated into the nitroxide-polymer lithium iron phosphate battery, PTMA/LiFePO4. Together, they improve the lithium ion intercalation capacity, cycle life, electrochemical performances, and conductivity of batteries.

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.
