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 Sienna Swagger Wagon rides again with Busta Rhymes

Let's face it: there are few things less "gangsta" than a minivan (which goes a long way towards explaining why crossovers have been gradually taking their place as the family-hauler of choice across America, but we digress). The point here is not lost on Toyota, which has embraced the uncool image of the minivan with the Swagger Wagon campaign.
We first saw the suburban-goes-urban campaign pop up with the introduction of the new Sienna back in 2010. And now that the Sienna's been updated for 2015, the campaign is back again, featuring none other than Trevor Tahiem Smith, Jr. himself... better known to most as Busta Rhymes. The decidedly white-bread video spot that follows may make you cringe, but you've got to admit that it's well done, even if it doesn't have the charm and freshness of the original.

Toyota bringing updated Avensis to Geneva

The upper end of Toyota's sedan lineup in America may be all about the Camry and Avalon, but that's not the case everywhere in the world. Back home in Japan, Toyota offers the Crown and the Mark X. But in Europe, it all comes down to the Avensis. And the Japanese automaker is about to roll out an updated version at the upcoming Geneva Motor Show. The Avensis, for those unfamiliar, is Toyota's challenger to the likes of the Ford Mondeo (which we know as the Fusion) and the Volkswagen Passat, available in both sedan and wagon forms. It was first introduced in 1997 and is currently in its third iteration, but what you see here is not the fourth-generation model but an update on the MkIII that hit the European market in 2009. Full details on the refreshed model have yet to be disclosed, but the new Avensis clearly benefits from revised styling – carried out at the company's design studio in the South of France, with production to continue at the Burnaston plant in the UK. Expect a revised interior, updated equipment and a new engine range to also be part of the mix when the new Avensis is revealed in full early next month in Switzerland. TOYOTA TO REVEAL NEW AVENSIS AT THE GENEVA MOTOR SHOW Toyota will reveal the new Avensis at the Geneva motor show (3 – 15 March), the latest development of its contender in the European mid-size (D-segment) car market. New Avensis has been styled at Toyota's ED2 design studio in the South of France and developed by the company's R&D centre in Brussels. It will be built by Toyota Manufacturing UK at the Burnaston car plant, near Derby. The new model will deliver innovations in comfort and safety and will feature a new range of engines that promise both performance and efficiency. Avensis has been designed to appeal to fleet and private customers alike. Toyota will present new Avensis and host a press conference on its stand at the Geneva motor show at 12:15 on 3 March.
