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.

Judge reduces damages in fatal Hyundai crash to $81M

Hyundai no longer has to pay $248 million as part of a court ruling from a fatal accident in Montana that killed two cousins in a 2005 Tiburon. The judge hearing the appeal revised the amount down to a total of about $81 million. She upheld the original $8.1 million in actual damages but reduced the punitive damages to $73 million from the previous $240 million.
According to Bloomberg, the judge refused Hyundai's desire to reduce the amount even further. She said in her court order that the company showed "an indifference to or reckless disregard of the health and safety of the motoring public."
In the original case, the families' attorneys alleged that the cracking of a faulty steering knuckle caused the fatal accident. Hyundai argued that fireworks had been let off inside the vehicle, which caused the driver to swerve and crash. In a statement released after the ruling, the automaker claimed that evidence supporting its defense was barred from the trial. According to Bloomberg, had the original amount of damages been upheld, it would have been the sixth-highest amount awarded by a jury in the US this year.

Hyundai dealerships getting global makeover

In the near future, almost no matter where you're at in the world - whether in Mexico or France - you may not be able to tell an immediate difference between Hyundai dealers. The Korean brand plans to remove some of the diversity from its showrooms in favor of a unified design everywhere outside of the US by about 2020.
The plan is called the Global Dealership Space Identity, and the end result features a modern, open showroom with floor-to-ceiling glass to look in and a bronze-colored roof section (pictured above). The goal of the unified design "is to strengthen our Modern Premium brand consistency across all dealerships, proving premium emotional experiences related to our brand and increase interaction with customers," said Hyundai spokesperson Sookjin Hwang to Autoblog via email.
The ball is already rolling on the plan with the cues being implemented at new dealers in Mexico and about 42 other showrooms worldwide. In the future even Canada may use it, according to Automotive News. "Hyundai Motor plans to fully implement the new identity worldwide within five years (2014~2018). The exact timing for each country will be different."
