Marca Doeff is Division Deputy of the Energy Storage and Distributed Resources Division (ESDR), a Senior Scientist and member of the Energy Storage Group (ESG) at Lawrence Berkeley National Laboratory. She has worked on materials for electrochromics, lithium and sodium polymer batteries, lithium ion batteries, solid-state lithium batteries, and sodium ion batteries with aqueous or organic electrolytes. This work has resulted in publication of approximately 150 peer-reviewed journal articles, book chapters, and extended abstracts as well as six patents.
Marca is currently Secretary of the Electrochemical Society. She has co-organized several symposia on batteries for the International Conference on Advanced Ceramics and Composites (American Ceramics Society) and the Electrochemical Society including a recent one on room temperature sodium batteries.
Additionally, Marca has been invited to speak at numerous prestigious international conferences:
- American Chemical Society meetings in Boston (Fall 2011) and New Orleans (Spring 2013)
- Pacific Rim Meeting on Electrochemical and Solid-State Science/222nd Meeting of the Electrochemical Society (October 2012)
- Power Our Future conference in Vitoria-Gasteiz, Spain (March 2012)
- Pacific Power Symposium in Waikoloa, HI (January 2010 and 2012)
- International Conference on Materials for Advanced Technologies in Singapore in July 2007 and 2009.
Marca was a finalist in the Center for Entrepreneurship and Technology CleanTech Innovation Awards, April 2008. She served on the Technical Affairs committee of the Electrochemical Society from 2003-2007 and as a member-at-large of the Battery Division of the Electrochemical Society from 2010-2012. Also, she has served on review panels for the National Science Foundation Materials Research Science and Engineering Centers (MRSECs) and for the Department of Energy ARPA-E.
Marca has been married to Douglas Taube since October 1990, and enjoys participating in outdoor activities such as hiking, bicycling, and skiing as well as traveling to exotic locales like Indonesia and Peru with him. She also participates in yoga and dance and is very fond of cats.
2020 R&D 100 Award: Solid Lithium Battery - October 05th 2020
Solid Lithium Battery (SLiB) Using Hard and Soft Solid Electrolytes
The lithium battery market is expected to grow from more than $37 billion in 2019 to more than $94 billion by 2025. However, the liquid electrolytes used in most commercial lithium-ion batteries are flammable and limit the ability to achieve higher energy densities. Safety issues continue to plague the electronics markets, as often-reported lithium battery fires and explosions result in casualties and financial losses.
In Berkeley Lab’s solid lithium battery, the organic electrolytic solution is replaced by two solid electrolytes, one soft and one hard, and lithium metal is used in place of the graphite anode. In addition to eliminating battery fires, incorporation of a lithium metal anode with a capacity 10 times higher than graphite (the conventional anode material in lithium-ion batteries) provides much higher energy densities.
The technology was developed by Berkeley Lab scientists Marca Doeff, Guoying Chen, and Eongyu Yi, along with collaborators at Montana State University.
