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 hydrogen vehicle visits CES, on sale in US in 2015

If there was ever any doubt that Toyota loves hydrogen vehicles, just listen to some of what Bob Carter, senior vice president of automotive operations for Toyota Motor Sales, USA, said today at the Consumer Electronics Show (CES) in Las Vegas: "Fuel cell electric vehicles will be in our future sooner than many people believe, and in much greater numbers than anyone expected." "Hydrogen works beautifully with oxygen to create water and electricity and nothing more." "This [hydrogen] infrastructure thing is going to happen." "I believe what I'm going to tell you about today is going to change our world." Sounds like love is in the air. In all seriousness, Toyota is incredibly bullish on the future of hydrogen as a part of the automotive landscape, and is now gearing up for the 2015 launch of its hydrogen sedan. The concept version of the car was shown for the first time at the Tokyo Motor Show last fall and is making its North American debut at CES today, alongside the still-under-camo engineering prototype. The reasons for Toyota's hydrogen confidence? The debut vehicle is supposed to be a "reasonably priced" car that has a range of 300 miles and a refueling time of about five minutes. Carter highlighted the engineering work that Toyota has done over the past decades to get the fuel cell system downsized while upping power output to over 100 kW. He also said the vehicle will have carry enough energy to power a house for a week, so company engineers are working on an export power supply device. The H2 Toyota sedan will start sales in California (the only state in the US where there are currently any hydrogen stations) next year. The automaker is working with the University of California Irvine's Advanced Power and Energy Program (APEP) to figure out where to build the next series of public hydrogen fueling stations. Today there are ten, but the model Toyota is using "is based on the assumption that owners want to reach a refueling station within 6-minutes" and shows that 68 stations would be able to serve around 10,000 hydrogen vehicles.
