Dyson has been publicly bullish on the technology, and has stated that it is “committed to investing £1bn in battery technology over the coming years, and Sakti3 is an essential and exciting part of that program.”[1][2] HistorySakti3 is a battery company co-founded by Dr. Ann Marie Sastry, regarded as a globally influential battery technology innovator,[3] in 2007 as a spin-out from University of Michigan in Ann Arbor, Michigan.[4] Publications by Sastry and her collaborators have been cited over 6,400 times.[5] She and her former students apparently formed the company; most have remained at the firm, according to a recently granted patent.[6] Work by this group, including Dr. Chia-Wei Wang, Dr. Yen-Hung Chen, Dr. Xiangchun Zhang, Dr. Myoungdo Chung, and Dr. HyonCheol Kim, has been cited extensively (collectively over 4100 times).[7][8][9] As reported in Scientific American,[10] Sakti3 claimed to achieve 1143 Wh/L in volumetric energy density in its prototype solid-state lithium battery cells in 2014. In 2015, Sakti3 was invited to the first ever White House Demo Day by President Barack Obama to showcase its innovations.[11] In 2015, Sakti3 was acquired by Dyson Ltd.[12] They initially paid $15m for an undisclosed stake,[13] this being Dyson's first outside investment. Later in the year, Dyson paid another $90m for the rest of Sakti3. Other investors had included Beringea, General Motors, Khosla Ventures and Itochu.[14] TechnologySakti3 has described methods for producing scalable solid-state batteries, using thin film deposition guided by numerical simulations and optimization[10][15] and apparently used multiple deposition techniques.[16] Sakti3 has been recognized with several technical awards, including MIT Technology Review's Top 50 Most Disruptive Companies in 2012,[17] and MIT Technology Revie Sakti3 has grown its intellectual property portfolio to 94 patents and patents pending.[1][2] In 2017, it abandoned its licenses of its early University of Michigan patents.[1][2] Workplace CultureSakti3 has been recognized multiple times for excellence in workplace culture. Sakti3 has won the AWE Workplace Excellence Seal of Approval Award for its for “exemplary commitment to building excellent places to work” in 2015,[20] 2016,[21] and 2017.[22] Sakti3 has been named 101 Best and Brightest Companies to Work For in 2015[23] and 2016[24] for its “commitment to excellence in their human resource practices and employee enrichment.” Sakti3 was also awarded Crain’s Detroit Cool Places to Work in Michigan in 2016.[25] CriticismSakti3 has been criticized for its secretive nature, a trait it apparently shares with its acquirer. Dyson takes great measures to protect its technology and is “as secretive” as Apple.[26] During a tour of Dyson’s facilities, a New York Times reporter observed that “employees remain tight-lipped, even among themselves, about their projects;” “prototypes were covered in tarps while large areas of the open-plan offices were off limits;” and “machinery in some of the research labs was obscured with black trash bags.”[26] Several months earlier, former employees (who were not on staff at the time of acquisition), have criticized the company. Fabio Albano, Marc Langlois, and Steve Buckingham claimed that the company’s early patents and methods were useless, and that Sakti3 was using an unscalable stacked cell configuration.[33] Claims made by the company over technological advances as well as its secretive behavior regarding sharing data have been criticized by former employees and media following the acquisition by Dyson.[27] The only independently verified data on Sakti3's prototypes by the United States Department of Energy show a capacity of 2.4 mAh, only capable of powering very small devices.[28] Steve Buckingham, a former employee, has publicly expressed his disappointment with the small area (1 cm²) of the best cell produced. Bob Kruse, formerly GM's most senior electric vehicle executive,[29] stayed on as COO for less than 2 years.[27] In November 2017 Ann Marie Sastry, Sakti3's founder, unexpected and quiet exit from the company stoked speculation that the company oversold their early successes.[30] SpeculationIn an interview by Car and Driver in 2015,[31] when asked the readiness of Sakti3’s batteries for automotive applications, Dr. Ann Marie Sastry responded that Sakti3 would first go to markets where their batteries can meet regulatory standards for the products and pointed out that durability standards for batteries in automotive applications are very different from phones or vacuums. The company has been praised for staying afloat and ultimately being acquired in a well-documented acquisition, amidst an intense period of bankruptcies in cleantech.[32] It has been pointed out that it takes a decade to invent a new hardware technology, and more than another decade for the invention to reach the hands of consumers.[32] It took James Dyson 15 years and 5,127 attempts to perfect his flagship vacuum.[33] References1. ^1 2 {{Cite web|url=https://cleantechnica.com/2017/04/04/promising-sakti3-battery-seems/|title=UPDATED: Sakti3 & Dyson Still Rolling|website=CleanTechnica|access-date=2017-07-31}} 2. ^1 2 {{Cite news|url=http://www.ibtimes.co.uk/dyson-electric-car-dreams-dashed-key-battery-patents-cast-aside-1615020|title=Out with the old, in with the new: Dyson drops old battery patents in solid state cell push|last=Charlton|first=Alistair|date=2017-04-03|work=International Business Times UK|access-date=2017-07-31|language=en}} 3. ^{{Cite book|title=Innovators in Battery Technology, Profiles of 93 Influential Electrochemists|last=Desmond|first=Kevin|publisher=McFarland|year=2017|isbn=978-0-7864-9933-5|location=|pages=194–197}} 4. ^{{Cite web|url=http://sakti3.com/?page_id=47|title=About {{!}} Sakti|website=sakti3.com|language=en-US|access-date=2017-07-31}} 5. ^{{Cite web|url=https://scholar.google.com/citations?user=kAHYv08AAAAJ&hl=en&oi=ao|title=Ann Marie Sastry - Google Scholar Citations|website=scholar.google.com|access-date=2017-07-31}} 6. ^United States Patent 9,627,709 7. ^{{Cite web|url=https://scholar.google.com/citations?user=WLE_WSkAAAAJ&hl=en|title=Chia-Wei Wang (汪家偉） - Google Scholar Citations|website=scholar.google.com|access-date=2017-07-31}} 8. ^{{Cite web|url=https://scholar.google.com/citations?user=iW_Dv8kAAAAJ&hl=en&citsig=AMstHGQWTgkAzCS7oTUx5euEYIVPLWAuoQ|title=Yen-Hung Chen - Google Scholar Citations|website=scholar.google.com|access-date=2017-07-31}} 9. ^{{Cite web|url=https://scholar.google.com/citations?user=EJF9b3gAAAAJ&hl=en&oi=ao|title=Xiangchun Zhang - Google Scholar Citations|website=scholar.google.com|access-date=2017-07-31}} 10. ^1 {{Cite news|url=https://www.scientificamerican.com/article/secretive-company-claims-battery-breakthrough/|title=Secretive Company Claims Battery Breakthrough|last=Fletcher|first=Seth|work=Scientific American|access-date=2017-07-31|language=en}} 11. ^{{Cite news|url=https://obamawhitehouse.archives.gov/the-press-office/2015/08/04/new-details-president-obama-hosts-first-ever-white-house-demo-day|title=New Details: President Obama Hosts First-Ever White House Demo Day|date=2015-08-04|work=whitehouse.gov|access-date=2017-07-31|language=en}} 12. ^{{Cite news|url=https://www.telegraph.co.uk/finance/newsbysector/industry/11941317/Dyson-buys-up-rest-of-solid-state-battery-company.html|title=Dyson buys up rest of 'solid-state' battery company|work=Telegraph.co.uk|access-date=2017-03-09|language=en}} 13. ^{{Cite news|url=https://www.telegraph.co.uk/finance/newsbysector/industry/engineering/11468735/Dyson-makes-first-external-investment-with-move-into-batteries.html|title=Dyson makes first external investment with move into batteries|work=Telegraph.co.uk|access-date=2017-03-09|language=en}} 14. ^{{Cite news|url=https://www.greentechmedia.com/articles/read/what-sucked-dyson-into-backing-battery-maker-sakti3|title=What Sucked Dyson Into Backing Battery Maker Sakti3?|access-date=2017-03-10}} 15. ^{{Cite web|url=https://www.youtube.com/watch?v=Z3TNRfS-8q8|title=Ann Marie Sastry {{!}} Solid state energy storage: Game-changing technology for the 21st century|website=YouTube|language=en|access-date=2017-07-31}} 16. ^United States Patents 9,127,344 and 9,240,584 17. ^{{Cite news|url=http://www2.technologyreview.com/tr50/2012/|title=50 Disruptive Companies 2012 - MIT Technology Review|last=Review|first=MIT Technology|work=MIT Technology Review|access-date=2017-07-31}} 18. ^{{Cite news|url=https://www.technologyreview.com/s/538511/survival-in-the-battery-business/|title=Big Prospects for a Small Battery|last=Martin|first=Richard|work=MIT Technology Review|access-date=2017-07-31|language=en}} 19. ^{{Cite news|url=http://www.crainsdetroit.com/article/20140629/NEWS/306299993/8-sakti3-inc-ann-arbor|title=8.
