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 offers three free years of Blue Link safety tech [w/videos]

As of now, the Assurance Connected Care service that Hyundai introduced at the New York Auto Show with the 2014 Genesis sedan is complimentary for three years on any vehicle equipped with the company's Blue Link telematic systems. It's the third service package to join the Blue Link suite, after Essentials and Guidance.
Assurance Connected Car provides owners with monthly vehicle reports, maintenance alerts, notification of diagnostic trouble codes and safety features like SOS emergency assistance and automatic collision notification sent to Blue Link agents. The service can also be transferred to new owners within the three-year timeframe. Owners who already have Blue Link can add Assurance Connected Care "at a reduced price," but Hyundai hasn't said what that price is yet.
There's a press release below with more details and four commercials to show you just what you could be missing out on.

Hyundai sued in Korea over inflated fuel economy claims

Hyundai remains in hot water in its home market after the South Korean Ministry of Land, Infrastructure and Transport alleged that the country's largest automaker, along with Ssangyong, misstated fuel economy numbers on some of its crossovers. Now, though, the country's consumers are going after Hyundai, with a lawsuit from 1,500 Santa Fe owners.
The suit was filed in Seoul Central District Court by a firm called Yeyul. Its spokesperson, Kim Woong, said the suit was a sign that angry consumers could go after the manufacturer if they're wronged by a company's product.
"It is essential that as many affected consumers as possible take part in this lawsuit to show not just the carmaker but the rest of the companies in Korea that you can get a red card if you mess with your customers," Kim told Bloomberg.
