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 amalgamates motorsports divisions under Gazoo Racing

Toyota has more racing divisions than we could wave a checkered flag at, with the company's various motorsport activities all coordinated by different operations. But the Japanese industrial giant is now bringing most (if not all) of them under one roof. From here on in, any racing that was done under the Toyota Racing, Lexus Racing or Gazoo Racing banners will now be united under the latter. That includes the LFAs it races around the Nurburgring, the TS040 Hybrid it fields at Le Mans and in the World Endurance Championship, the Yaris it will soon throw at the World Rally Championship, the Lexus racers that compete in the Super GT championship back in Japan... the works. The move does not appear to affect Toyota Racing Development, the automaker's American arm that handles its NASCAR racing activities, but from here on out, any Toyota or Lexus you see racing on most anything but a speedway will be competing under Gazoo Racing. The move appears to be more than symbolic and semantic, putting its racing vehicle development, technical support and marketing activities in the hands of the new Motor Sports Group. In announcing the consolidation, Toyota highlights in particular the benefit its various racing programs bring to its talent pool, if not the direct effect they have on the company's vehicles themselves. Toyota Racing, Lexus Racing and GAZOO Racing Unite Under GAZOO Racing Toyota City, Japan, April 9, 2015-Starting April 11, Toyota will unite all motorsports activities under GAZOO Racing. The move will clarify the role of Toyota's motorsports in its efforts to make ever-better cars and foster new generations of car enthusiasts. Until now, Toyota has participated in competitions around the world-including the World Endurance Championship (WEC), the Super GT in Japan, and the Nurburgring 24 Hours endurance race-through the separate Toyota Racing, Lexus Racing and GAZOO Racing teams. Of those, GAZOO Racing in particular was created to expand the role of promoting motorsports beyond that of traditional automakers, and carry out grassroots activities aimed at creating new and ever-growing generations of car enthusiasts. Concerning today's announcement, Toyota President Akio Toyoda said: "Our founder Kiichiro Toyoda once said that motorsports are vital to the evolution of car making and the entire auto industry.

Toyota Prius remains best-selling vehicle in California, wireless charging tests underway

About one in every nine new cars in the US are sold in the California. If we're just looking at the four Toyota Prius hybrid variants, then the number becomes closer to one in three. Tesla Model S battery-electric vehicle sales? Try one in 2.7. For the second straight year, the Prius was the best-selling car in the Golden State. Toyota sold 69,728 Priuses there, almost a third of the more than 234,000 sold in the US in 2013. Prius sales in California alone were up almost 13 percent. And Toyota's ready to build upon that momentum with a new version of the Prius Plug-in Hybrid, saying that it's testing a wireless recharging system in Japan's Aichi Prefecture and will start similar tirals stateside later this year. We'll make the wild prediction that some of those tests, which involves magnetic resonance, will be in California. Meanwhile, Tesla's numbers were, in their own way, were more impressive. The California-based automaker sold 8,347 of its Model S units in the Golden State out of about 22,300 nationwide in 2012, Bloomberg News reports. In all, advanced-powertrain vehicles accounted for 9.3 percent of California new-vehicle sales, compared to 3.8 percent for the country, Bloomberg says, citing Hybrid Cars and Baum & Associates. Check out Toyota's press release on its California sales below. Prius Medals In The Golden State Toyota Prius is best-selling vehicle line in California Wireless charging testing for Prius Plug-in TORRANCE, Calif., Feb. 18, 2014 /PRNewswire/ -- The Prius took home the gold in 2013 as the most popular vehicle-line in California for the second year in a row. The Prius Family (Prius Liftback, Prius v, Prius c and Prius Plug-in) took the podium in both 2012 and 2013 as the best-selling California vehicle name plate. 69,728 drivers hit the road in 2013, according to the California Auto Outlook Report, while 61,893 Californians joined the family in 2012. In the Golden State, the Prius Family outsells all other hybrid competitors combined. California drivers lead the country in adoption of vehicles powered, either wholly or partially, by electricity. 9.3% of vehicles sold in the state run on some form of electricity, according to the report. But despite the growing number of hybrid competitors, Toyota's hybrid leadership remains unmatched. In fact, one out of every two hybrids in California carries the Prius name plate.
