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 …

Business Insider reported, “But Håkansson and Dube knew their creation could go even faster.

KillaJoule is the world’s fastest electric motorcycle with a top speed of 241 mph (388 km/h) so far.  About 80 percent of this sleek bullet is the design and work product of co-owner and driver Eva Håkansson, who has graced the stage at two Electric Aircraft Symposiums, the last appearance with her husband and crew chief, Bill Dube’.  Their web site explains, “KillaJoule is really eco-activism in disguise. The only purpose of this 19 foot, 400 horsepower, sleek, sexy motorcycle is to show that eco-friendly doesn’t mean slow and boring.” Over the Labor Day weekend, Eva lowered her petite frame (she’s about five feet tall) into the cockpit of her speedy sidecar to break her old world record and set …
