Worldwide Battery Developments

Worldwide, batteries are getting a great deal of backing, but probably not at the level of China’s push to rule over world electric vehicle markets.  Recently, China awarded BYD $3.7 billion to enable it to pursue dominance of the world EV market.  According to Bloomberg.com, “Virtually all of China’s listed companies received direct handouts in 2022, the Kiel Institute [for the World Economy] said, flagging support for wind, solar and railway rolling stock companies. Industry aid in China is “at least three to four” times higher than in large EU and OECD countries, the group said.” The European Union is busy investigating China’s underwriting of its own auto industry in what the EU sees as an anti-competitive advantage in an ongoing EV price war.  America, for the most part, and aside from relatively minor Advanced Research Project Agency – Electric (ARPA-E) funding, does not seem to encourage EV development. What usually starts with automotive advancement eventually finds its way skyward.  …

A123/Solid Power Partnership – A Safe Bet?

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 mild hybrid applications.   Solid Power, a startup based on research done at University of Colorado Boulder, combines (“an exceptionally”) high-capacity cathode with a high-capacity lithium metal anode and a high ionic capacity solid separator.  This combination produces, according to …
