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.

Hurricane Sandy cost automakers 15,000 vehicles, may have ruined up to 200k

Hurricane Sandy was the largest Atlantic storm in US history, and its total economic impact is just now coming into view. According to Automotive News, Toyota, Chrysler, Nissan and Honda are set to scrap around 15,000 new vehicles ruined by the storm. Nissan alone accounts for about 40 percent of those, with 6,000 Nissan and Infiniti models deeded "un-saleable" due to damage. The company saw 56 dealerships shuttered due to the storm, but 51 of those have since reopened.
Toyota, meanwhile, had some 4,000 vehicles at its Newark port facility, and of those, 3,000 may be scrapped. An additional 825 were dealer inventory when they were ruined. Honda and Acura dealers are reportedly sending 3,440 vehicles to the salvage yard. By comparison, Chrysler weathered the storm fairly well with 825 units destroyed, while Hyundai suffered only 400 lost units and Kia scrapped around 200.
As you may recall, Fisker also suffered some losses, and Automotive News reports the manufacturer saw 320 Karma models damaged beyond repair. Ford and General Motors have yet to come up with estimates, and no automaker has commented on the full cost of replacing the vehicles.

Hyundai leased 70 Tucson fuel-cell vehicles in first year

Since going on sale in the early summer of 2014, Hyundai has leased around 70 of its hydrogen fuel-cell-powered Tucson CUVs. That's the number that Mike O'Brien, Hyundai's vice president of corporate and product planning, revealed at a green vehicle event in Huntington Beach, CA, this week. There's a reason for the low number, O'Brien said. "Of course, everybody asks 'Why 70?' and it's basically tied to the number of fuel stations that are available," he said. "We were the first to actually pass over ownership of the vehicle, it's not a test program. It helps people put their money on the table, and they lease the car from us and it's their car. The customers that we've leased the vehicle to are ones that live close to a fuel station. "Right now there is less than 10 in the state of California. By the end of this calendar year, there should be in the mid-20s. And then, of course, under Gov. Jerry Brown's $200 million towards construction, I believe about 100 stations [will come online] through the end of the next couple of years. As those stations get built out, we're taking more and more applications for vehicle sales." In January 2014, O'Brien told AutoblogGreen that 88,000 people had expressed an interest in owning a fuel-cell Tucson. O'Brien said that Hyundai needs the customers to be close to a hydrogen station so that driving the car feels similar to what they're used to doing. "We just want to make sure there is a satisfying experience of ownership, and that's the most important thing, to make that their ownership experience matches what they've experienced with a gasoline car," he said. The Hyundai Tucson Fuel Cell can be leased for $499 a month, which includes free refueling. For the 2016 model year, the Tucson FCV gets HomeLink connectivity in the rear-view mirror and two new exterior colors, Hydro Blue and Chromium Silver, in addition to the already available Winter White. 2016 Hyundai Tucson Fuel Cell Continues To Attract Zero-Emissions-Focused Customers With New Colors And Features World's First Mass-Produced Fuel Cell Vehicle Available For $499 per month Lease Includes Unlimited Free Hydrogen Refueling and At Your Service Valet Maintenance FOUNTAIN VALLEY, Calif., May 22, 2015 /PRNewswire/ -- Hyundai's zero-emissions, hydrogen-powered Tucson Fuel Cell vehicle continues to satisfy and attract new customers focused on high-versatility and clean transportation.
