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.

Ford barely edges surging Chrysler for Canadian sales crown in best year ever

The auto industry in the US showed strong results through much of 2014 with sales regularly growing year-over-year for many brands. That same trend carried over in the Great White North, as well. Canada posted its best numbers ever with 1.85 million units sold, up about 100,000 vehicles over 2013. The country nearly had a new market leader, too. The big winner among our neighbors to the north in 2014 was Ford with 291,951 vehicles sold, up 3 percent from 2013, according to Reuters. That success also handed the company the sales crown for the fifth consecutive year. In large part, the strong result came from the company's popular trucks, which represented about 80 percent of overall sales. "Ford moved into the number one position in September and didn't look back," said a note to clients by DesRosiers Automotive Consultants quoted by Reuters. However, the Blue Oval didn't exactly take an overwhelming lead for the year. The company nearly had to hand over the sales trophy to FCA after the company rallied in the latter part of the year. The Italian-American conglomerate had its best results ever to nip at the Ford's heels and move 290,004 units for 2014, a 12-percent improvement from last year. Jeep especially helped the bottom line with over 50-percent growth, according to Reuters. Only two other brands were able to break the 200,000-vehicle barrier in Canada for 2014. General Motors came in third place overall with 249,800 sales, up 6.3 percent. The combined Toyota and Lexus also barely jumped the hurdle with 200,851 units moved, a 2.8 percent improvement.

Toyota C-HR hybrid crossover coupe concept leak ahead of Paris

Last week, Toyota previewed an upcoming concept called the C-HR and promised it would debut at the upcoming Paris Motor Show. It didn't say much more or give us anything beyond a silhouette and the shape of the lights, but here we have the first images of the finalized form.
The C-HR envisions a hybrid crossover coupe with angular styling that looks ready to take on the Nissan Juke. It's far sportier than a RAV4, and looks closer to how we'd imagine the next-generation Scion FR-S would look like if it were riding on a jacked-up suspension - with some show car elements thrown in for good measure, like a gloating roof, radical lighting and the usual absence of door handles and usable wing mirrors.
Of course, this being a Toyota concept, it packs a hybrid powertrain, although specifications did not leak out along with the images. Overall the form looks pretty striking, if decidedly unsubtle. We'll look forward to bringing you more as the Paris show rapidly approaches.
