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.

Daimler, Toyota, BMW to lead $10-billion hydrogen investment

Daimler, BMW, and Toyota are leading a group of 13 companies pledging to invest more than $10 billion during the next five years to spur enough infrastructure-building and technology advancements to get more of the general public to buy hydrogen fuel-cell vehicles. The automakers, which also include Honda and Hyundai, as well as companies such as Shell, AirLiquide, Linde Group, and Total SA, are part of what they're calling the Hydrogen Council. The group made its announcement in Davos, Switzerland, on Tuesday. The Hydrogen Council will pledge to accelerate its rate of hydrogen-related investments, which currently stand at about $1.5 billion annually. The coalition says its work represents a continuation of the 2015 Paris Agreement, in which many of the companies agreed to address the issue of climate change. The group says that hydrogen, which emits water vapor when used in fuel-cell vehicles, "can play an important role in the transition to a clean, low-carbon, energy system." The Hydrogen Council also vowed to push global governments to accelerate public investment in hydrogen-related infrastructure. Relative to other drivetrain technologies, hydrogen fuel-cell vehicles are in their relative infancy in terms of adoption because of the high cost of both building fuel cell vehicles and setting up a hydrogen-refueling infrastructure. Toyota is the only automaker that sells a production fuel-cell vehicle in the US. The Japanese company, which introduced its Mirai domestically in late 2015, sold 1,034 of them in the US last year. Daimler subsidiary, Mercedes-Benz, used Tuesday's announcement to remind people that it would start selling its GLC plug-in hydrogen fuel-cell crossover this year. There are only 33 publicly accessible hydrogen refueling stations in the US, including 30 in California, and one each in Connecticut, Massachusetts, and South Carolina, according to the US Department of Energy. By comparison, there are more than 15,000 electric-vehicle charging stations with almost 40,000 outlets in the US.

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.
