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.

2013 Hyundai Elantra GT

GT Stands For "Generous Trunk"
If ever there were an award for the most bastardized label in the automotive world, the Gran Turismo/Grand Touring/GT moniker would be an easy frontrunner. Once reserved solely for sporty coupes, the GT letters have taken a big hit over the years, but things got downright embarrassing with the BMW 5 Series Gran Turismo. For 2013, Hyundai is helping to muddy the waters even further by slapping a GT badge onto the hatchback version of its top-selling model, the Elantra.
In the case of the 2013 Hyundai Elantra GT, though, this name is just recycling the Elantra GT name from the early 2000s, albeit on a more stylish, modern and all-around better five-door. Hyundai has created quite a competitive lineup since its Fluidic Sculpture design language hit the market, but one area that it has paled in comparison to rival automakers is in the hatchback department. With a plethora of budget-minded compact cars currently on sale, Hyundai now finds itself in the unique position of being the only automaker to offer a compact sedan, coupe and hatchback with the 2013 Elantra. Still, with the compact segment more crowded than a public school classroom, we spent a week with the new Elantra GT to see how it stacks up against the hatchback competition.

2014 Hyundai Azera gives you more for less

The Azera is sort of the forgotten Hyundai. Despite just having rolled out the new version a couple of years ago, the Korean automaker hasn't been able to move them very quickly. Where the smaller Sonata and Elantra sell in the tens of thousands each month, the fullsize Azera barely reaches that in a year. In fact it's Hyundai's second slowest-selling model, behind the flagship Equus. But Hyundai's not resigning itself to letting Azeras sit around on dealer lots. Thus, the company is actually reducing the car's price while increasing the array of standard equipment.
Now starting at $31,000, the base 2014 Azera now comes with a six-inch color LCD, backup camera, blind-spot mirror and three years of Assurance Connected Care services. Spring for the $34,750 Azera Limited and you get an eight-inch display, electroluminescent gauges, LCD trip computer and power folding mirrors.
Despite the increased level of specification, the Azera is now $1,250 cheaper than the previous-year model, while still offering the highest specific output and most front-seat room in its class. Scope out the details in the press release below and the fresh batch of images in the gallery above for a closer look.
