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.

Gladiators, Pilots, and Palisades, plus a couple boring crossovers | Autoblog Podcast #562

On this week's Autoblog Podcast, Editor-in-Chief Greg Migliore is joined by Consumer Editor Jeremy Korzeniewski. The duo discuss the leaked Jeep Gladiator, Ford's Baby Bronco, the Aston Martin DBX, and then touch on other reborn names like the Honda Pilot. They also discuss how boring crossovers have taken over as the family car of choice in the United States and debate the merits of turbocharged V6 engines versus the classic American V8.

Hyundai N 2025 Vision Gran Turismo Concept looks ready for Le Mans

It's Bugatti versus... Hyundai? Yes, the revered hypercar manufacturer is facing some stiff competition for coolest car at the 2015 Frankfurt Motor Show from the affordable South Korean brand, and it's because both companies chose the German show to introduce their Vision Gran Turismo Concepts. While we'll leave Bugatti's entry to another scribe, we're going to spill plenty of ink on the new N 2025 Vision Gran Turismo, Hyundai's entry to the eponymous video game's well-received Vision program. While so many of these concepts have some basis in reality, Hyundai has tossed out its production vehicles in favor of a far racier concept. Yes, the N 2025 looks better suited to the 24 Hours of Le Mans prototype class than an auto show stage. Details are scarce – automakers don't usually give out a lot of info on powertrains and the like in these Vision GT cars – but Hyundai says it "highlights sustainable technology," which makes us think that there's some kind of hybrid drivetrain underneath that aerodynamic body. Perhaps the coolest thing about the N 2025, though, is that it's not hard to imagine it on a race track of the future. Hyundai has only ever really played around in the World Rally Championship, but with this Vision GT car, it shows the South Korean brand may have the chops for a much higher tier of racing. Check out the photos from Frankfurt and let us know what you think about this latest Vision Gran Turismo car. Hyundai Motor's New High Performance Sub-brand 'N' Takes Center Stage at Frankfurt Motor Show - The sub-brand N will build new momentum for an exciting driving performance and provide emotional driving experience for customers - The latest motorsport challenger and two dynamic concepts will also be introduced at the Motor Show August 26, 2015 – Hyundai Motor will showcase its high performance sub-brand N at the Frankfurt International Motor Show 2015. The result of intensive testing and product development, the sub-brand N builds on Hyundai Motor's successful motorsport experiences and technology capability to drive future performance-oriented and race-track-capable models forward and bring 'the most thrilling winding road' fun to customers who truly love cars. The N builds on not just Hyundai Motor's continued advancement as a primary competitor in World Rally Championship (WRC) but also on the company's dedication and investment to create striking and pioneering high performance cars.
