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's rakish HND-9 concept has lots of Seoul

Hyundai has unwrapped the HND-9 Sports Coupe Concept at the 2013 Seoul Motor Show. The design study is intended to give the world a glimpse at what Hyundai has planned for the look of its future products - an evolution of the automaker's current Fluidic Sculpture design language.
With classic front-engine, rear-wheel-drive proportions, the HND-9 looks great, and engineers graced the concept with a 3.3-liter turbocharged, direct-injection engine good for 364 horsepower. An eight-speed automatic transmission shuttles that thrust to the rear wheels, while touches like butterfly doors give the machine a bit of flair.
Indoors, the HND-9 features seats built with a special mesh that changes colors depending on the viewer's angle. Designers modeled the cabin after a cockpit for a close, sporty feel. You can check out the full press release below for more information.

2018 Hyundai Sonata Sport Quick Spin Review | Returning to the revolution

The 2018 Hyundai Sonata represents a course correction of the sort that just wasn't needed with the previous-generation model. Besides a few added features here and there, that car really didn't change much during the course of its lifetime, and frankly, it didn't need to. When something works, don't screw it up. It arrived at a time when Honda and Toyota were pretty much phoning it in, and boasted a revolutionary design that quite literally changed the way midsize family sedans look to this day. Toyota designer Ian Cartabiano told me that Sonata was one of the few cars over the years that made his fellow designers wake up a bit and realize the game was changing. Then, after staging a revolution, Hyundai played it safe. The Sonata introduced three years ago was conservative to the point of anonymity outside, while not really moving the needle on the vehicle dynamics front. If there was one, clear area where that revolutionary Sonata fell short -- and indeed virtually every Hyundai -- it was in the sophistication and poise it demonstrated out on the road. Well, after the cool reception to the model redesign, Hyundai got a wake up call of its own. This 2018 Hyundai Sonata gets a rather significant facelift, adopting the curvy trapezoidal grille found on more recently introduced models, and ditching its conservative anonymity for a more organic overall appearance certainly in keeping with its "Fluidic Sculpture" predecessor. The rear was also redone with more tapered, dare I say "aggressive" taillights and the license plate relocated to the bumper. Is the end result a great-looking car? Shoulder shrug, but it's sure better than before.

I was quite frankly not expecting it to drive different, because when you review cars long enough, you start to know what a particular brand's cars feel like behind the wheel. There'll be subtle changes over the years, but the language remains the same. Well, the Sonata has been hitting the Rosetta Stone. The change is immediately apparent. The on-center steering feel is crisp, the turn-in more immediate and effort is consistent. It just feels "right" now whereas before turning the Sonata was one of numb indifference.
