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.

Toyota recalling 342k Tacomas due to faulty seatbelt pretensioners

Toyota is voluntarily recalling 342,000 Tacoma Access Cab pickups, produced between 2004 and 2011. The wide-ranging recall is due to faults in the screws that attach the belt pre-tensioner to the belt retractor. There are concerns that the screws can loosen themselves over time, especially if the access door is opened and closed with too much force. It's important to note that the recall only covers the driver and front passenger seat, and is limited to just the Access Cab trucks. Other body styles aren't affected.
If the screws come loose, the pre-tensioner and retractor spring could separate from the belt entirely, which would be bad news in a crash. There's no mention of injuries or accidents due to the faulty pre-tensioners. Owners affected by the recall will be notified soon, and asked to come in for recall service.

America was the unexpected theme at the 2017 Detroit Auto Show thanks to Trump

President-elect Donald Trump was not in attendance at this year's Detroit Auto Show, but it sure seemed like he was the target audience for many of the press conferences and announcements surrounding the event. Several manufacturers chose to play up existing and future commitments to the US in general and American jobs specifically in their presentations to the press, and we're pretty sure that has everything to do with Trump's recent targeting of automakers on Twitter. To us, it seemed automakers were going on the offensive to try and preempt any future tweet-shaming for investing in auto manufacturing anywhere but the US. The pro-America sentiment started the week prior to the auto show, with Ford announcing that it would build several future electrified vehicles at its Flat Rock Assembly Plant in Michigan and also cancel a $1.6 billion factory planned for Mexico. Ford announced the two items on the same day, but the reality is that they likely have no relation to each other; the Mexican plant is being skipped because the company doesn't need the extra capacity to build the Ford Focus right now. Trump was still happy to share the news on Twitter. Then, on Sunday, FCA announced it would invest $1 billion in manufacturing plants in Ohio and Michigan to produce the new Jeep Wagoneer, Grand Wagoneer, and Wrangler-based pickup. It's not as though those potential new jobs were on their way out of the US, necessarily, but FCA took the opportunity to mention that plant upgrades at the Warren Truck Plant would allow the company to build Ram heavy duty trucks, which are currently assembled in Mexico, there. CEO Sergio Marchionne confirmed that Trump and his proposed tariffs had nothing to do with the decision. We certainly believe that, but we also have to believe that the timing of the release, positive outcome for America, and zero gain for Mexico were all orchestrated. Again, Trump sent out a victory tweet as if this had been his doing. Ford then used its press conference at the show on Monday to reiterate the plans for Flat Rock and also confirm that the Ford Bronco and Ranger nameplates will be returning to the US market, and that both will be built at a plant in Michigan. Announcements of manufacturing locations are usually aimed at the UAW, which certainly has a stake in these things, but again this one was broadcast to the auto show crowd in general.
