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.

Vote to unionize Toyota Canada plant faces delay

Volkswagen isn't the only automaker with high-profile unionization efforts afoot at one of its North American factories. Unifor, Canada's largest private-sector union, is attempting to organize Toyota's factories in Ontario, reports Reuters. A vote was originally set for next week, but Unifor has apparently found more workers eligible to vote, delaying the proceedings. It hasn't rescheduled the ballot yet, but claims there are 7,500 employees with the right to vote, with over 3,000 having already signed union cards.
Toyota is pushing against organizing, saying that workers already have a payment and benefits near the top of the industry, and noting that it has never laid off a permanent employee in Canada. Unifor has reportedly countered by saying that about a quarter of the workforce is operating under a temporary contract, which receives lower benefits.
The automaker has three factories in Ontario - two in Cambridge and one in Woodstock. To form a union, a majority of eligible employees must vote to join Unifor. If successful, they would be the first wholly owned Toyota plants in North America to be organized. Previous attempts to unionize the Japanese automaker's Canadian factories in 2001 and 2008 failed due to lack of support.

Question of the Day: What (non-Skyline) JDM car to import?

I have been looking into the idea of bringing a four-wheel-drive kei van over from Japan, something like a Honda Street or perhaps even a Mitsubishi Minicab Bravo Route 66, and so I have been researching the various bureaucratic hoops I must jump through in order to bring such a car into my state (Colorado). When I finally tracked down the state official who knew the answers, his very first words were "OK, so what year Skyline do you want to register here?" Yes, Nissan's not-sold-over-here factory-hot-rod of the 1980s and 1990s is what gets shipped over most often, but there are other worthy JDM vehicles. Say, for example, a stunning 1990 Mitsuoka Le Seyde (above), which was far classier than the Excalibur and based on the sporty S13 Nissan Silvia, aka 240SX. Of course, the king of JDM cars is the mighty Toyota Century, and you can get nice legal-to-import examples for reasonable prices. No, you can't get the V12 Century legally – yet; the V12-powered cars don't hit the 25-year-old mark until 2022. So, what's your choice for a 1991 or earlier Japanese-market car to import, assuming that the Skyline is off the table? Related Video: Auto News Honda Nissan Toyota Car Buying nissan skyline questions
