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.

U.S. VP Harris pledges to consult S. Korea over EV subsidy concerns

TOKYO/SEOUL — U.S. Vice President Kamala Harris told South Korea's prime minister on Tuesday that Washington will work to address Seoul's concerns over recently enacted electric vehicle (EV) subsidies that could disadvantage Asian automakers. The $430 billion "Inflation Reduction Act" bill enacted in August includes a host of U.S. President Joe Biden's priorities, including investments to roll back climate change and make Washington a world leader in the EV market. Among the law's provisions are requirements that EVs be assembled in North America to qualify for tax credits. The law also ends subsidies for other EV models and requires that a percentage of critical minerals used in those cars' batteries come from the United States or an American free-trade partner. Harris, visiting Japan, met with South Korea's Han Duck-soo and "underscored that she understood (Korean) concerns regarding the Act's tax incentives for electric vehicles, and they pledged to continue to consult as the law is implemented," the White House said. A senior Biden administration official said extensive conversations have already taken place within the U.S. government over how to address South Korea's concerns. "She listened very carefully and made clear our commitment to work within the U.S. government — the U.S. Trade Representative, the Treasury Department — as we look ... to help address that issue," the official said. Biden has sought to deepen business with South Korea as part of a bid to increase U.S. manufacturing jobs and build a united front against China, who he views as the country's key ideological and economic competitor. Korean officials see the new requirements as a betrayal after South Korean companies agreed to make major investments and build factories in the United States. Heavily industrialized South Korea worries the new subsidies will set back Hyundai Motor Co and its affiliate Kia Corp in the world's largest consumer market. Cars are South Korea's third-largest export.

2013 Hyundai Veloster Turbo: May 2013

Although I went on the Portland launch of the regular-strength Veloster back in late 2011, my time in the Turbo model was previously limited to one very brief commuting experience, so I was glad to get some time in our long-term matte gray model this month. In a way, I lucked out, grabbing the key fob to our Hyundai just as the weather in mid-Michigan finally acknowledged spring's existence. The temperature change afforded us the chance to swap out the all-season Kumho Solus KH25 rubber that it arrived with in January for its optional ($1,200) Michelin Pilot Super Sport tires (215/40ZR18), an almost absurdly major-league, high-dollar set of shoes for what is actually only a hottish hatch.
You might have expected the Veloster Turbo to slide under the radar in such high-performance and shouty company, but the truth is it was a little magnet for attention.
With the new footwear freshly installed, I made a beeline for South Bend, Indiana for the start of this year's One Lap of America, an event I've been staffing for well over a decade. I rolled into the Tire Rack headquarters' expansive parking lot, parking the VT alongside the competitors, whose vehicles appeared "cunningly disguised as racecars," covered with all manner of sponsorship stickers and graphics. You might have expected the Veloster Turbo to slide under the radar in such high-performance and shouty company, but the truth is it was a little magnet for attention.
