Amy Prieto is a Professor of Chemistry at Colorado State University and the Founder and Chief Technical Officer of Prieto Battery.
Prieto received her Bachelor of Arts degree in chemistry and philosophy from Williams College in 1996. There, she undertook an honors thesis entitled "The Synthesis and Characterization of Precursors to Zirconium-Containing Liquid Crystals" under the mentorship of Lee Young Park. Before beginning her doctoral work, she was a summer research fellow at Bell Labs, which she credits with fostering an appreciation for cross-disciplinary collaboration. [1] She then attended the University of California, Berkeley, where she received her PhD in inorganic chemistry in 2001. For her graduate work, she worked in the laboratory of Angelica Stacy on her thesis entitled Electrodeposition of Nanostructured Thermoelectric Materials working to synthesize solid-state materials. [1]
Following her PhD, she began a postdoctoral fellowship at Harvard University, working in the Nanoscale Science and Engineering Center in Hongkun Park's research group, where she studied and characterized the electronic properties of single molecules and nanoparticles. [1]
In 2005, Prieto joined the faculty at Colorado State University as a synthetic chemist and materials scientist. Prieto's research program focuses on Lithium-ion batteries, as well as developing nanoparticles and nanowire structures for a variety of applications.
In 2009, she founded Prieto Battery. [2] The company is geared towards developing and commercializing a rechargeable battery that will last longer, charge faster, and be free of toxic or flammable materials that make up traditional batteries. [1] It took her four years to form the company and an additional five to develop a working prototype. [3] By 2014, Prieto and collaborators had created a small pilot production line in her laboratory at CSU to demonstrate their viability to larger investors.
Unlike traditional batteries, Prieto's battery is solid-state, meaning the battery uses solid electrodes and a solid electrolyte, rather than liquid or polymer gel electrolytes. [4] The battery makes use of a three-dimensional copper foam that undergoes a coating process through two electroplating steps: one to create a positively charged electrode (anode made of copper antimonide) and one to create the negatively-charged electrode (cathode). [1] Because the foam is a porous 3-dimensional material, the electroplating coats both the foam's outer surface and its pores, creating a high surface area for ion transfer. The company claims that ions travel shorter distances than in conventional batteries, increasing power density (20C) [5] and reducing charging times. This makes Prieto's battery charge faster and store more energy than lithium-ion batteries. [6] [7] The batteries are lightweight, flexible, use non-toxic materials, can come in a variety of shapes, and do not overheat or catch fire. [8] [5]
Investors in Prieto Battery include Stanley Ventures and Intel Capital. [7] In 2016, Prieto demonstrated her batteries to Stanley Black & Decker, using one of their 3D printers. [7]
Electrochemistry is the branch of physical chemistry concerned with the relationship between electrical potential difference and identifiable chemical change. These reactions involve electrons moving via an electronically-conducting phase between electrodes separated by an ionically conducting and electronically insulating electrolyte.
An electrode is an electrical conductor used to make contact with a nonmetallic part of a circuit. Electrodes are essential parts of batteries that can consist of a variety of materials depending on the type of battery.
In chemistry and manufacturing, electrolysis is a technique that uses direct electric current (DC) to drive an otherwise non-spontaneous chemical reaction. Electrolysis is commercially important as a stage in the separation of elements from naturally occurring sources such as ores using an electrolytic cell. The voltage that is needed for electrolysis to occur is called the decomposition potential. The word "lysis" means to separate or break, so in terms, electrolysis would mean "breakdown via electricity."
Electroplating, also known as electrochemical deposition or electrodeposition, is a process for producing a metal coating on a solid substrate through the reduction of cations of that metal by means of a direct electric current. The part to be coated acts as the cathode of an electrolytic cell; the electrolyte is a solution of a salt of the metal to be coated; and the anode is usually either a block of that metal, or of some inert conductive material. The current is provided by an external power supply.
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: within the next 30 years, their volumetric energy density increased threefold while their cost dropped tenfold.
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.
Nanodot can refer to several technologies which use nanometer-scale localized structures. Nanodots generally exploit properties of quantum dots to localize magnetic or electrical fields at very small scales. Applications for nanodots could include high-density information storage, energy storage, and light-emitting devices.
A nanowire battery uses nanowires to increase the surface area of one or both of its electrodes, which improves the capacity of the battery. Some designs, variations of the lithium-ion battery have been announced, although none are commercially available. All of the concepts replace the traditional graphite anode and could improve battery performance. Each type of nanowire battery has specific advantages and disadvantages, but a challenge common to all of them is their fragility.
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.
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.
A solid-state battery is an electrical battery that uses a solid electrolyte to conduct ion movements between the electrodes, instead of the liquid or polymer gel electrolytes found in conventional batteries. Solid-state batteries theoretically offer much higher energy density than the typical lithium-ion or lithium polymer batteries.
Nanoarchitectures for lithium-ion batteries are attempts to employ nanotechnology to improve the design of lithium-ion batteries. Research in lithium-ion batteries focuses on improving energy density, power density, safety, durability and cost.
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. It was invented by the Iranian/American chemist Ali Eftekhari in 2004.
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 cost.
In materials and electric battery research, cobalt oxide nanoparticles usually refers to particles of cobalt(II,III) oxide Co
3O
4 of nanometer size, with various shapes and crystal structures.
Lithium–silicon batteries are lithium-ion battery that employ a silicon-based anode and lithium ions as the charge carriers. Silicon based materials generally have a much larger specific capacity, for example 3600 mAh/g for pristine silicon, relative to the standard anode material graphite, which is limited to a maximum theoretical capacity of 372 mAh/g for the fully lithiated state LiC6.
Silicon nanowires, also referred to as SiNWs, are a type of semiconductor nanowire most often formed from a silicon precursor by etching of a solid or through catalyzed growth from a vapor or liquid phase. Such nanowires have promising applications in lithium ion batteries, thermoelectrics and sensors. Initial synthesis of SiNWs is often accompanied by thermal oxidation steps to yield structures of accurately tailored size and morphology.
