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.

New Ford Mustang incoming; driving the Tesla Model S Plaid | Autoblog Podcast #746

In this episode of the Autoblog Podcast, Editor-in-Chief Greg Migliore is joined by Road Test Editor Zac Palmer. We're fast approaching the reveal of the 2024 Ford Mustang, and we talk about what we know so far. We also discuss what's next for the Chrysler 300, McLaren is mulling an electric crossover, we've got more Civic Type R details, and Mitsubishi's Ralliart sub-brand is making its return to America. We've been driving a Tesla Model S Plaid, Kia Sportage X-Pro and Kia EV6, and we give our final thoughts on our long-term loan of a Hyundai Palisade.

2019 Hyundai Kona Electric gets 250-mile range rating in the U.S.

Let's get the most salient details out of the way: The Hyundai Kona Electric will show up in California in the fourth quarter of 2018, and other "ZEV-focused states" will soon follow. We'd expect to see the Kona EV in dealerships along the East and West Coasts and in New England in early 2019. It'll have an estimated range of 250 miles from its 64 kWh lithium ion battery pack. Its electric motor sends 201 horsepower and 291 pound-feet of torque to the front wheels. Other markets get a lower-cost, entry-level model with less power and range, but the U.S. will only get this lone range-topping version. View 15 Photos Those specs put the U.S. Kona EV squarely into the thick of the burgeoning electric vehicle market, where it will compete with cars like the Chevy Bolt EV (238-mile range) and Tesla Model 3 (up to 220-mile range). The Nissan Leaf has a much lower 151-mile range. The Kona EV can be fully charged at Level 2 in in a little less than 10 hours. DC fast charging capability is standard on the Kona, and it can go from zero to an 80 percent charge in less than an hour. Cargo capacity stands at 19.2 cubic-feet, which is identical to the gas-powered Kona. The EV also benefits from a standard multi-link rear suspension setup in place of the standard gas-powered, front-wheel-drive model's low-tech torsion beam system. Normal, Eco, and Sport drive modes alter the steering feel and powertrain programming to either emphasize acceleration and performance or maximize range. Hyundai didn't make sweeping changes to the look of the standard Kona in its conversion into an electric vehicle. The helmet-shaped grille of the standard car gives way to a more aerodynamically efficient design with lightly debossed slashes and dashes. The door covering the charging port is also housed in the grille. Split lighting units remain front and rear, and thick plastic cladding lends a utilitarian look to the lifted hatchback profile. It doesn't scream 'electric vehicle' like the Toyota Prius or Hyundai's own Ionic, but differs sufficiently from the gas-powered Kona to make it easy to spot on the road. The rest of the Kona EV package is well-sorted for daily driving duties. A full suite of active and passive safety systems come standard as part of the Hyundai Smart Sense package, including forward collision avoidance with pedestrian detection, rear cross-traffic collision avoidance, blind-spot warning, and lane-keeping assist.
