A123/Solid Power Partnership – A Safe Bet?

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

A123 Systems has worked with buffering chemistries to reduce the volatility of lithium batteries for the last decade.  Solid Power Inc. has taken a set of interesting new technologies to make batteries more energy dense and safer.   The two companies are combining efforts to make a more powerful, less-volatile battery, according to recent press releases. A123 produces nanophosphate (lithium iron phosphate – LiFePO4) and ultraphosphate batteries.  Their nanophosphate batteries are used in Porsche’s 919 hybrid, a LeMans Prototype (LMP1) endurance racer that was outright winner of the event this year.  They also power Eva Hakansson’s Killajoule and Bill Dube’s Killacycle – both record-holding electric motorcycles.  Their Ultraphosphate line is designed to work at low voltages and low temperatures, including 48-Volt …

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 …
