Fisker’s Plans for Cars and Patents for Solid-State Batteries

Dean Sigler Batteries, Sustainable Aviation 0 Comments

Is there a Fisker battery in the future of electric vehicles?  The latest proclamations from Henrik Fisker indicate he is ready to launch a lovely four-seat car for CES 2018, and that it will have LG Chem batteries capable of powering the vehicle for 400 miles.  Charging the batteries for nine minutes will add 125 miles range.  That’s definitely competitive, but Fisker promises more for a future EMotion supercar. Fisker claims that machine will have newly-patented solid-state batteries that charge in a minute, have 2.5 times the energy density of currently available lithium batteries, and will be far cheaper to manufacture than today’s cells.  That’s in 2023, five years out. Five Years Out “Five years out” has been the refrain …

Yi Cui and team Devise a 10X Anode

Dean Sigler Batteries, Electric Aircraft Components, Sustainable Aviation 0 Comments

Batteries are complex things to design and make, with materials scientists and chemists facing unlimited numbers of options for materials choices, formulations and proportions, and manufacturing techniques that will make hoped-for performance attainable on a commercial level. Yi Cui and a distinguished array of undergraduate and graduate students at Stanford University have written 320 academic research papers since 2000, with the rate of publication seeming to increase every year. To put icing on that multi-layered cake, Dr. Cui has helped found his own battery company, Amprius, using his depth of knowledge to take batteries in directions interesting enough to draw the attention of well-known investors – including Stanford.  The only recent information on the web site today shows the firm …

Deformable Flexible and Conductive – A Great Solid Electrolyte

Dean Sigler Batteries, Electric Aircraft Materials, Electric Powerplants, Sustainable Aviation 0 Comments

Reporting on a new material that doesn’t seem real, a joint research team from Ulsan National Institute of Science and Technology (UNIST) and Seoul National University in Korea says it has developed a “highly-conductive, highly deformable, and dry-air-stable glass electrolyte for solid-state lithium-ion batteries.  If those characteristics seem mutually exclusive, the electrical performance helps dispel skepticism. Assisted by colleagues at Lawrence Berkeley National Lab and Brookhaven National Lab, the researchers prepared the electrolyte using a “homogenous methanol solution,” and wetting exposed surfaces of the electrode active materials with the solidified electrolyte. Eureka Alert! quotes Professor Yoon Seok Jung  (UNIST, School of Energy and Chemical Engineering) , “The research team also developed a material for the solid electrolyte by adding the iodized lithium …

Bosch Doubles Down on Solid-State Batteries

Dean Sigler Electric Aircraft Components, Electric Powerplants, Sustainable Aviation 0 Comments

Bosch, the German electronics giant, is making a strong showing at the Frankfurt Motor Show (IAA), and showing off its solid-state Li-ion battery technology.  It recently acquired Seeo, Inc., an American startup that has been developing such a battery for several years, and will add Seeo’s research to its own expertise and exclusive patents. Encouragingly, the company says it will be able to double the energy density of Li-ion batteries while cutting prices by half.  Perhaps discouragingly, Bosch says this will take until 2020 to bring to production. Green Car Congress quotes Dr. Volkmar Denner, chairman of the board of management for Robert Bosch GmbH, claiming a breakthrough.  “Bosch is using its knowledge and considerable financial resources to achieve a …

Dr. Yi Cui’s Latest, a Solid-state Electrolyte

Dean Sigler Electric Powerplants, Sustainable Aviation 0 Comments

Green Car Congress reports that, “Stanford researchers led by Professor Yi Cui have used ceramic nanowire fillers to enhance the ionic conductivity of polymer-based solid electrolyte by three orders of magnitude. The ceramic-nanowire filled composite polymer electrolyte also shows an enlarged electrochemical stability window.” With solid-state batteries coming to the fore through efforts by Ann Marie Sastry at Sakti 3 and Qichao Hu at Solid Energy Systems, an improved solid electrolyte would seem to offer greater battery safety and stability “when compared with conventional liquid electrolytes. The abstract for the Stanford researchers’ paper in the journal ACS Nano Letters explains that “Currently, the low mobility of lithium ions in solid electrolytes limits their practical application. The ongoing research over the past few …

We tend to think of batteries as being inanimate objects, even though they expand, contract and flex their electric muscles within their cylindrical or pouch forms as they charge and discharge.  This type of internal wiggling helps reduce and finally destroy the battery’s ability to make our remotes change channels or keep our airplanes flying. Researchers at the Beijing Institute of Technology have found a way to use the product of much internal and external wiggling, natural silk that is “biomass-derived” and processed to form carbon-based nanosheets that might be used in lithium-ion batteries and other energy storage devices. The American Chemical Society reports that Chuanbao Cao and his researchers worked with the idea that carbon is a key component …

Boeing and Embraer Embrace on Biofuels

Brazil may become a central research and manufacturing site for biofuels, with Boeing and Embraer opening a joint sustainable biofuel research center, something that will rely on Brazil’s fertile land to supply non-food plants with which to make jet fuel.  Working in the Boeing-Embraer Joint Research Center in the São José dos Campos Technology Park, opened in January 2014, the companies are continuing to “focus on technologies that address gaps in creating a sustainable aviation biofuel industry in Brazil, such as feedstock production, techno-economic analysis, economic viability studies and processing technologies.” Boeing’s Research & Technology-Brazil (BR&T-Brazil) Center, one of the company’s six international advanced research centers, leads the collaboration with Embraer and works with Brazil’s research-and-development community “to grow Brazil’s …

Will VW Take on Tesla?

Volkswagen just bought a five-percent stake in a startup company called QuantumScape, a commercial spinoff of work done at Stanford University’s Nanoscale Prototyping Laboratory for Energy Conversion and Storage.  The Labroratory’s head, Fritz B. Prinz, Finmeccanica Professor of Engineering and Robert Bosch Chairman of Mechanical Engineering, explains: “Our team creates, models, and prototypes nanoscale structures to understand the physics of electrical energy conversion and storage. We are exploring the relation between size, composition, and the kinetics of charge transfer. We are also interested in learning from nature, in particular by studying the electron transport chain in plant cells.” (Note that the QuantumScape web site is curiously without detail, showing only four pretty pictures and making three or four non-controversial statements. …

Transformative EV Range Expansion?

Dean Sigler Electric Powerplants, Sustainable Aviation 2 Comments

In what may be eventual good news for future electric aviators, the U. S. Department of Energy (DOE) Advanced Research Projects Agency – Energy (ARPA-E) will award approximately $36 million to 22 projects to develop transformational electric vehicle (EV) energy storage systems using innovative chemistries, architectures and designs.  ARPA-E also uses the term, “revolutionary.” The series of awards is part of the RANGE program (Robust Affordable Next Generation Energy Storage Systems), intended “to enable a 3X increase in electric vehicle range (from ~80 to ~240 miles per charge) with a simultaneous price reduction of > 1/3 (to ~ $30,000). If successful, these vehicles will provide near cost and range parity to gasoline-powered ICE vehicles, ARPA-E said.” “Transformational” comes straight from the CAFE …
