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 GT86 convertible on 'indefinite hold'

Bad news, sportscar fans. According to a new report from What Car?, Toyota has cancelled plans to produce a GT86 convertible, a model based on the FT-86 Open Concept that debuted at the 2013 Geneva Motor Show. In truth, Toyota never actually confirmed it would produce the budget-friendly droptop in the first place, but rumors have been flying since last year and Toyota reportedly showed its embattled Scion dealers a FR-S version of the convertible in August. Presumably, this means that a lidless variant of the Subaru BRZ is not in the cards, either.
The reason for the move is unknown, though What Car? reports "one possible cause is weight; Toyota did say that further work would be required on rigidity before the convertible could be launched, and that could have added extra bulk that conflict with the regular GT86's ethos of light weight and agile handling." It doesn't look like that work will happen anytime soon, as "sources now say that the car has now been delayed indefinitely, with no place in Toyota's product plan in either 2014 or 2015." Still holding out hope? What Car? says the project could be "fast-tracked" if management decides it wants to reboot the program down the road.

Honda, Subaru airlifting parts to bypass port labor diputes

It should be abundantly obvious that a vital element in building cars is actually having the components on hand to assemble them. A labor dispute on the West Coast between the International Longshore and Warehouse Union and management is not making that quite so easy for some Japanese automakers. Work slowdowns at the ports have pushed Honda and Subaru parent Fuji Heavy Industries into flying some parts into the country. The two automakers began shipping by airplane late last month to avoid production delays, according to Bloomberg, but it has been an expensive solution. Subaru's chief financial officer said the decision cost around $60 million more per month than sending components by cargo ship. They aren't the only companies dealing with the problem, either. Toyota reportedly stopped overtime assembly at some of its factories here because of the delays in getting parts, according to Bloomberg. The dockworkers have been negotiating on a new contract since May 2014, and the current offer on the table to them has offered a 3 percent raise, according to Bloomberg. Although, the union is reportedly considering another slowdown at 29 ports along the West Coast in the coming days.
