Life and career

Takeuchi is the daughter of Mary (Marija) and Rudolf Sans (Rūdolfs Sāns), Second World War refugees from Latvia. Rudolf and Mary fled Soviet-occupied Latvia for Germany in 1945, living in a refugee camp for several years, ultimately immigrating to the United States.

Takeuchi graduated from the University of Pennsylvania in 1975 having majored in chemistry and history. She then worked on her Ph.D. in organic chemistry at the Ohio State University until 1981, under the direction of Dr. Harold Shechter. Her graduate research focused on the reactions of alkoxides with (chloromethyl)trisubstituted silanes.

While working on her Ph.D., she met Kenneth J. Takeuchi and the two married on May 15, 1982.

After completing post-doctoral training in electrochemistry at the University of North Carolina at Chapel Hill and the University of Buffalo, she worked at Greatbatch Inc. in Clarence, New York for 22 years. It was here, under the funding of Wilson Greatbatch, that Takeuchi continued development of the Li/SVO battery. She has also worked on batteries for neuro stimulators, drug delivery systems, pacemakers, and also industrial batteries for environments concerning high temperatures, vibrations, and need of reliability.

In 2007, she joined academia at the University of Buffalo as the Greatbatch Professor of Advanced Power Sources. She is currently a distinguished professor at Stony Brook University in the departments of chemistry, and material science and engineering. She was selected as the 2013 recipient of the E.V. Murphree Award in Industrial and Engineering Chemistry, sponsored by Exxon Mobil. Takeuchi is also a Fellow of The Electrochemical Society and served as the organization's president from 2011–2012.

Current/recent

On July 16, 2018, Takeuchi’s company has been awarded a $12 million grant from the Department of Energy. They aim and want to focus on the development of batteries that are high energy and high power, which has traditionally been complicated and unfeasible. These batteries could be used in electric vehicles or in combination with renewable solar energy systems and renewable energy farms. The company also has several projects funded by the DOE and supported by partners such as Mercedes-Benz. One particular project is focused around increasing the energy content of the negative electrode within electric vehicles and a secondary project is centered around increase the energy content of the positive electrode. A third program is focused around enabling electric vehicles to charge faster. Together, they will be able to increase the range of current electric vehicles and make EVs a much more feasible and enticing option/competitor to traditional gasoline vehicles.

Vision

Takeuchi visions to create an entity bringing together Stony Brook, Brookhaven National Lab, federal funding, state funding, industry, and philanthropy, creating an institute focused on energy and the environment.

Innovation

Takeuchi has been primarily recognized and awarded for her innovation regarding implantable cardiac defibrillators. Millions of people around the world rely on these devices. For these devices to be easily miniature and reliable, they needed to be connected to an energy source that was also characteristically similar. Takeuchi’s innovation allowed for such devices to effectively function. The innovation is a new type of battery technology regarding a new cathode material, highly conductive electrolyte, and a novel cell design enabling high power and resulting in the creation of a silver vanadium oxide battery. These batteries are highly powerful, miniature in size, and have a long life. All of these characteristics greatly benefit ICD’s and their ability to help people with irregular rhythms and beating frequencies within their hearts. Every year, there are more than 300,000 ICDs implanted, and every year, the silver vanadium oxide battery is the dominant battery used by these devices. These SVO batteries are able to last for around five years, compared to the life of around a year for the other forms of batteries. Being implanted into the body, the life of such an implant is crucial. If traditional forms of batteries are used, patients usually have to go through surgery every year to replace the devices and ensure the functionality of the implant. With the SVO batteries, the batteries last much longer, over five times, and therefore patients don’t have to have their devices replaced as frequently. Initially launched into the marketplace it the late 1980s and early 1990s, these SVO batteries are still prevalent and widely used today.
