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 …

ORNL and Solid Power Sign Lithium-Sulfur Agreement

Solid-state batteries are becoming the next big thing in energy storage, with the promise of low volatility, high energy density and lower-cost manufacturing.  With academia, industry and government collaborating on the next wave of development, we may see progress in this realm. Recently, the Department of Energy’s Oak Ridge National Laboratory and Solid Power Inc. of Louisville, Colo., signed an exclusive agreement licensing lithium-sulfur materials for next-generation batteries. A team of current and former ORNL researchers including Chengdu Liang, Nancy Dudney, Adam Rondinone, Jong Keum, Jane Howe, Wujun Fu, Ezhiylmurugan Rangasamy, Zhan Lin and Zengcai Liu developed the technology.  This included designing and testing an all-solid lithium-sulfur battery “with approximately four times the energy density of conventional lithium-ion technologies.”  It featured a …

First Seeo, Now Sakti3

Bosch’s acquisition of Seeo Inc. is followed within seven weeks by news that an innovator in another area has acquired a battery developer. Electric-vehiclenews.com announced that “Dyson, the U.K. company famous for its bagless vacuum cleaners, has acquired Michigan-based solid-state battery startup Sakti3 for $90 million and announced plans to build an important $1 billion battery factory to mass produce the next generation battery technology.” The report noted this was the second recent purchase of a promising start-up company by a larger, richer firm.  Bosch acquired Seeo Inc. to benefit from its solid-state technology, which like most solid-state batteries would, among other benefits, reduce or eliminate fire hazards – something brought to the fore by recent FAA rulings on shipping of lithium …

ORNL Makes It Two for Two

Oak Ridge National Laboratory has announced that their researchers have built and demonstrated a high-voltage (5 V) lithium, solid-state battery with a usable life of more than 10,000 cycles, at the end which test the battery retains more that 90-percent of its original capacity.  That makes two such claims in a week, with ORNL’s battery comparable to that developed by Nanyang Technology University (NTU) and reported on in this blog last week. ORNL points out that, “For a given size of battery, the energy stored in a battery is proportional to its voltage. Conventional lithium-ion batteries use organic liquid electrolytes that have a maximum operating voltage of 4.3 V. Operating a battery above this limit causes short cycle life and …

2X Solid State Batteries?

Applied Materials, located in Sunnyvale, California, designs and makes equipment used in the manufacture of computer chips and other miniature electronic devices.  Your editor worked there on assignment from his engineering firm for six months 15 years ago, documenting and verifying the equipment and control systems for their newest facility.  Even then, miniature was wild understatement, with the company crafting machinery that could produce 0.18 µm lines in silicon chips.  In the last two decades, line widths have shrunk to 0.03 µm, and the number of elements on chips has increased proportionally.  This makes nano manufacturing a highly precise endeavor, and one which seems to defy credulity with lower costs for the ever-increasing number of chips being made. It’s this …

Transformative EV Range Expansion?

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 …
