Solid-state batteries: Why Toyota's plans could be a game-changer for EVs

Word out of Japan today is that Toyota is working on launching a new solid-state battery for electric vehicles that will put it solidly in the EV game by 2022. Which leads to a simple question: What is a solid-state battery, and why does it matter? Back in February, John Goodenough observed, "Cost, safety, energy density, rates of charge and discharge and cycle life are critical for battery-driven cars to be more widely adopted." And risking a bad pun on his surname, he seemed to be implying that all of those characteristics weren't currently good enough in autos using lithium-ion batteries. This comment is relevant because Goodenough, professor at the Cockrell School of Engineering at the University of Texas at Austin - it so happens, he turns 95 today - is the co-inventor of the lithium-ion battery, the type of battery that is pretty much the mainstay of current electric vehicles. And he and a research fellow at U of T were announcing they'd developed a solid-state battery, one that has improved energy density (which means a car so equipped can drive further) and can be recharged more quickly and more often (a.k.a., "long cycle life") than a lithium-ion battery. (Did you ever notice that with time your iPhone keeps less of a charge than it did back when it was shiny and new? That's because it has a limited cycle life. Which is one thing when you're talking about a phone. And something else entirely when it involves a whole car.) What's more, there is reduced mass for a solid-state battery. And there isn't the same safety concern that exists with li-ion batteries vis-a- vis conflagration (which is why at airplane boarding gates they say they'll check your carryon as long as you remove all lithium-ion batteries). Lithium-ion batteries may be far more advanced than the lead-acid batteries that are under the hood of essentially every car that wasn't built in Fremont, Calif., but as is the case with those heavy black rectangles, li-ion batteries contain a liquid. In the lithium-ion battery, the liquid, the electrolyte, moves the lithium ions from the negative to the positive side (anode to cathode) of the battery. In a solid-state design, there is no liquid sloshing around, which also means that there's no liquid that would freeze at low operating temperatures. What Toyota is using for its solid-state battery is still unknown, as is the case for the solid-state batteries that Hyundai is reportedly working on for its EVs.

Lexus gets new boss, and he's a designer

A reshuffle in the uppermost ranks of Lexus could see the Japanese luxury brand further energize its recent focus on design. Tokuo Fukuichi, Toyota's global design boss, is the new head of Lexus International.
Fukuichi will retain his role as the overall head of design for Toyota, Lexus and Scion, and will assume his new position at the head of Lexus and on its board on April 1 (no fooling). This is going to be an interesting move for fans of design to watch, as Fukuichi has repeatedly been mentioned as a designer that enjoys pushing the edge of the envelope and experimenting. He is, after all, the man responsible for designing the most awesomely odd minivan of the 1990s, the mid-engined, rear-drive Toyota Previa, and more recently, he signed off on the controversial Lexus LF-NX concept, which is said to presage a new production small crossover.
"Regarding changes in design, no one has 100 percent confidence," Fukuichi told Forbes back in January 2013. "No one can really say with pure certainty that, 'In two years, this will sell well.'" As Akio Toyoda continues to demand more assertive, edgier designs, it's that point of view that should make Fukuichi a valuable addition to Lexus, as it continues to challenge the competition from Germany.
