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.

Reprising The Recipe For A Perfect Slice Of Toast
My toaster broke the other week. Halfway through the process of cooking my gourmet Pop-Tart breakfast, the thing crapped out with a small bang, leaving my delicious morning treats trapped inside. To rectify the situation, I ventured out to a big box store, located the toaster aisle, and ran a couple of questions through my mind. Do I need two slots or four? Do I need to spend more than 20 bucks on this thing? Should I just buy a toaster oven to give me a wider range of bachelor-pad cooking functionality? After no more than two minutes of contemplation, I grabbed the cheapest one on the shelf, paid and left the store. The new toaster works just fine.
This sort of unemotional shopping experience is how I suspect people decide to purchase the Toyota Corolla. It's a perfectly fine appliance, and to a good number of people in the world, the bond between a car and a driver is no more important than the connection I feel to my toaster. Does it seat four people relatively comfortably? Does it get decent fuel economy? Is it easy to drive? Reliable? Safe? The Corolla checks all of these boxes, and because of that, Toyota managed to move just under 300,000 examples of the tenth-generation car in 2012 (though that number does include sales of the Corolla-based, now-deceased Matrix) - a vehicle that, at the time, was already six years old.

Toyota expects hybrids will soon reach 20-percent sales volume globally

Hybrids have come quite a long way from their roots as dull, slow, boring ecomobiles. Today, Porsche sells three hybrid models, one of which is the amazing 918 Spyder. BMW will soon sell four, including a low-slung, two-seat sports car. Even Ferrari and McLaren, full-fledged hypercar manufacturers, are embracing the tech. And all of these cars are sold alongside the same sort of boring cars that popularized hybrids in the first place. According to Toyota Chairman Takeshi Uchiyamada, though, we should see an even bigger increase in the number of hybrid vehicles in the coming years.
"I foresee hybrid models pretty soon reaching 20 percent of global sales from about 13 percent to 14 percent now," Uchiyamada-san told Automotive News. Uchiyamada is the man behind the original Prius, which gives him some degree of authority on making predictions about hybrid adoption.
What's remarkable, though, is that the 20-percent figure doesn't include plug-in hybrids, just gas- and diesel-electric models. "Suppliers need higher volumes to slash costs of components specific to plug-in models, including batteries that should be bigger and more capable than the ones used in traditional hybrids," Uchiyamada told AN.
