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.

This Hyundai commercial may be the weirdest of Super Bowl 50

It happens every year at the Super Bowl. For every headline-making, Twitter-breaking commercial, there's an ad like this one, simply titled "Better," from Hyundai. An ad that's so odd, people will focus not on its message, but the overarching weirdness of the spot. The ad in question follows the life of a man born with an exposed V8 engine where his heart should be (it's actually a little high, but we're nitpicking). Yes, it's as strange as it sounds. According to Hyundai, the man "strives to make the world a better place," but the only time we see anything approaching that is when he opens a jammed umbrella for a woman. For most of the ad, it's hard to tell you're even seeing a car commercial. It's not until the end, where the man is shown working in a Hyundai design studio alongside people with similar anatomical features, that the ad begins to make sense. Perhaps part of our disappointment with Hyundai's latest Super Bowl spot is that the NFL's official automotive sponsor has done so well otherwise. The brand has become a fixture during the big game over the years, and will likely see some success in 2016 with spots featuring both Ryan Reynolds and Kevin Hart. Those successes aside, though, we'll be surprised if there's a great response to this particular Super Bowl 50 commercial from Hyundai.

You can now Uber a Ford F-150 for tailgating at NFL games

The Ford F-Series has been named as the official truck of the NFL, whatever that means. To kick things off, the automaker is giving fans in New York the ability to order a "Built Ford Tough Tailgate Truck" on demand through Uber. The NFL-backed tailgate F-Series trucks will bring fans tailgate food, tickets, and merchandise. The ability to get a tailgate truck through Uber is currently limited to New York, but Ford will also offer a tailgate tour in various cities where NFL fans can win tailgate parties, tickets to games, and access to their own Ford tailgate truck. The sponsorship is for three years and includes America's best-selling truck, the Ford F-150, along with the automaker's Super Duty trucks. Ford is also giving NFL fans the ability to enter the "Built Ford Tough Toughest Ticket" sweepstakes for a chance to win Super Bowl LI tickets, along with a new 2017 Ford F-Series Super Duty decked out to showcase the winner's favorite football team. The NFL has partnered with various automakers in the past, with the most recent being a four-year deal with Hyundai in 2015. The Korean automaker is currently the official car, SUV, and luxury vehicle of the NFL, which conveniently leaves a spot for Ford's F-Series trucks to slot into. Hyundai took the sponsorship from General Motors, which had been a sponsor since 2001. Ford's new sponsorship comes at the perfect time as the new season official starts tomorrow with the Carolina Panthers taking on the Denver Broncos.
