Very nice piece, below a bare intro ...
The EV Battery Wish List Which automakers most want what in their ideal electric powertrain? by Lawrence Ulrich in IEEE Spectrum
Electric cars barely existed in 2010, when the Tesla Model S was still a glint in Elon Musk’s eye. Now more than 20 million EVs girdle the globe, according to BloombergNEF—and that count is expected to nearly quadruple to 77 million by 2025. A battery will be the high-voltage heart of each of those 77 million electric vehicles, and by far their most expensive component, setting off a worldwide race to ethically source their materials and crank up production to meet exploding demand.
EVs may have seized a record 5.8 percent of the United States market in 2022, according to J.D. Power, and could approach 11 percent of the global market this year. But experts still believe that better batteries, and many more of them, are a key to EVs reaching a market tipping point, even as Reuters projects automakers spending a whopping $1.2 trillion to develop and produce EVs through 2030.
IEEE Spectrum asked five industry experts to gaze deeply into their own crystal balls and outline what needs to happen in the EV battery space to wean the world off fossil-fueled transportation and onto the plug. Here’s what they said:
Emad Dlala, Lucid Motors, vice-president of powertrain
Upstart Lucid Motors hasn’t built many cars, but it’s built a reputation with the record-setting, 830-kilometer driving range of the Air Grand Touring Performance sedan. That range is a testament to Lucid’s obsessive pursuit of efficiency: The Air uses the same 2170-format cylindrical cells (supplied by Samsung SDI) as many EVs, but ekes out more miles via superior battery management, compact-yet-muscular power units and slippery aerodynamics. ...
