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.

Hyundai Tucson Fuel Cell CUV deliveries running behind schedule

Things are running a little bit behind on Hyundai's hydrogen-powered Tucson Fuel Cell CUV program in the US. The last time we checked in with the South Korean automaker's H2 project, we heard that the first deliveries were supposed to happen by the end of March. Speaking with Hyundai's Kevin Lee at the Hyundai booth at the SAE World Congress this week, we learned that deliveries are now going to happen closer to a month from now. Globally, there are roughly 70-100 of these hydrogen CUVs running in customer hands today. Lee told AutoblogGreen that the first US-bound units will be shipped from South Korea at the end of April or beginning of May but there is no actual date set for the first customer delivery. He said he expects 100 or fewer H2 powered Tucson CUVs to be operating in the US by the end of this year, all of them in Southern California. He said the customers in this first batch are being selected based on the location of the nearest hydrogen fuel station. While the number of stations is small today, more are on the way. Globally, there are roughly 70-100 of these hydrogen-powered CUVs (also known as the ix35) running in customer hands today, in places like South Korea, Germany, Norway, Austria and Italy. Some H2 stations charge Hyundai a flat rate per fill while others charge the automaker a general station maintenance fee. In the US, the Tucson Fuel Cell CUV leases for $499 a month (with $2,999 down) for 36 months, and comes with unlimited hydrogen refueling as well as Hyundai's Valet Maintenance. Lee told us that one reason for the "free" hydrogen is that even the small number of public hydrogen stations out there (nine in SoCal) does not have a cohesive set of rules for how to sell H2 to the public. The stations are not yet certified to charge customers based on dollar per kilogram in California, Lee said, since that regulation has not yet been set by the Division of Measurement Standards (DMS). Currently, "each station is different," he said, with some charging Hyundai a flat rate per fill and others charging the automaker a general station maintenance fee. This situation will likely change by the end of the year, he said. Lee said Hyundai is already busy working on the next-gen fuel cell vehicles and trying to reduce costs but was not able to share any details.

2019 Hyundai Veloster Turbo caught uncovered at video shoot

Here's the fully revealed Hyundai Veloster Turbo, and it appears to be moving pretty quickly based on the blur in the photos. That's understandable because our spy photographer got these shots during a video shoot of the Hyundai's latest hatchback in which it was probably being driven aggressively for good footage. Despite the blur, we can tell quite a bit from the images. First off, we know it's a Turbo model because of its large, round, center exhaust tips. We can also see that the Veloster is hopping on the contrast roof bandwagon, but at least to this editor's eye, the design seems well-suited to the paint scheme. The roof line itself also looks as though it drops down more drastically than the previous model. The rear window is notably wider than the old model, and the slimmer, wider taillights are flush with the glass. We're focusing more on the tail since we already got a good look at the front of the Veloster when Hyundai released official images of the car in snazzy multi-colored camouflage. The car's frown does look more pronounced in a single color, though. It seems the Turbo version also gets a small additional intake inlet in the bottom of the front bumper compared with the normal version. We expect to see the fully uncovered car in person at the 2018 Detroit Auto Show. It will likely appear alongside the less-powerful version. There's also an N version in the works, but it's possible Hyundai won't reveal that until later in the year. Related Video:
