Early life and education

Hatzell studied economics at Swarthmore College and mechanical engineering at Pennsylvania State University. [1] She moved to Drexel University for her doctoral research, where she studied flowable electrodes for water and energy technologies with Yury Gogotsi. [2] Her research involved electrochemistry, materials and colloidal science to create new electrode structures. She developed carbon-based and manganese oxide materials for scalable solid-state energy storage systems. [2] After graduating, she moved to the Lawrence Berkeley National Laboratory, where she developed soft and hard x-ray techniques to understand the properties of polymers. [3]

Research and career

Hatzell was appointed an assistant professor at Vanderbilt University. [3] [4] Hatzell joined Princeton University in 2021.[ citation needed ] Her research considers new materials for sustainable technologies, with a focus on solid-state and redox flow batteries. She is particularly interested in why batteries fail. [5] She identified that irregularities in electrolytes impacted the movement of ions, which could cause battery failure if the ions all migrated to particular locations. [6] Hatzell has created inorganic membranes for high energy density batteries and grid storage. [7]

Hatzell has developed strategies to minimize the costs of direct air capture systems, which generally require energy-intensive operating protocols to reduce the impact of carbon emissions and remove them from the atmosphere. These systems conventionally rely on heat or pressure changes to release captured carbon dioxide into storage (e.g. solvents heated to high temperatures). Hatzell developed an ion-exchange resin, which efficiently capture carbon dioxide at low humidity and release it at high humidity – without the need for high temperatures. [8]

<span class="mw-page-title-main">Lithium-ion battery</span> Rechargeable battery type

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">Vanadium redox battery</span> Type of rechargeable flow battery

The vanadium redox battery (VRB), also known as the vanadium flow battery (VFB) or vanadium redox flow battery (VRFB), is a type of rechargeable flow battery. It employs vanadium ions as charge carriers. The battery uses vanadium's ability to exist in a solution in four different oxidation states to make a battery with a single electroactive element instead of two. For several reasons, including their relative bulkiness, vanadium batteries are typically used for grid energy storage, i.e., attached to power plants/electrical grids.

<span class="mw-page-title-main">Flow battery</span> Type of electrochemical cell

A flow battery, or redox flow battery, is a type of electrochemical cell where chemical energy is provided by two chemical components dissolved in liquids that are pumped through the system on separate sides of a membrane. Ion transfer inside the cell occurs across the membrane while the liquids circulate in their respective spaces.

A zinc-bromine battery is a rechargeable battery system that uses the reaction between zinc metal and bromine to produce electric current, with an electrolyte composed of an aqueous solution of zinc bromide. Zinc has long been used as the negative electrode of primary cells. It is a widely available, relatively inexpensive metal. It is rather stable in contact with neutral and alkaline aqueous solutions. For this reason, it is used today in zinc–carbon and alkaline primaries.

<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">Capacitive deionization</span>

Capacitive deionization (CDI) is a technology to deionize water by applying an electrical potential difference over two electrodes, which are often made of porous carbon. In other words, CDI is an electro-sorption method using a combination of a sorption media and an electrical field to separate ions and charged particles. Anions, ions with a negative charge, are removed from the water and are stored in the positively polarized electrode. Likewise, cations are stored in the cathode, which is the negatively polarized electrode.

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.

In materials science, MXenes are a class of two-dimensional inorganic compounds along with MBenes, that consist of atomically thin layers of transition metal carbides, nitrides, or carbonitrides. MXenes accept a variety of hydrophilic terminations. The first MXene was reported in 2011 at Drexel University's College of Engineering.

A dual carbon battery is a type of battery that uses graphite as both its cathode and anode material.

The piezoelectrochemical transducer effect (PECT) is a coupling between the electrochemical potential and the mechanical strain in ion-insertion-based electrode materials. It is similar to the piezoelectric effect – with both exhibiting a voltage-strain coupling - although the PECT effect relies on movement of ions within a material microstructure, rather than charge accumulation from the polarization of electric dipole moments.
