Electric vehicle battery advances (IEEESpectrum)

Companies report a rush of electric vehicle battery advances in anodes, cathodes, and electrolytes suggest tomorrow’s EV power train may be quite different from today’s.

Electric vehicles have recently boasted impressive growth rates, more than doubling in market penetration every two years between 2014 and 2018. And batteries play a key role in EV performance and price. That’s why some companies are looking to new chemistries and battery technologies to sustain EV growth rates throughout the early 2020s.

Three recent developments suggest that executives are more than just hopeful. They are, in fact, already striking deals to acquire and commercialize new EV battery advances. And progress has been broad—the new developments concern the three main electrical components of a battery: its cathode, electrolyte, and anode.
