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.

Recharge Wrap-up: Couple wins Toyota Mirai; Tesla Gigafactory wages reported

A couple who won a Toyota Mirai at the Los Angeles Auto Show are among the first people to own the new fuel-cell sedan. Marianne Ellis bought the winning ticket - auctioned off by the Environmental Media Association to fund environmental programs - as a possible 30th anniversary gift for her husband, David. The excited couple picked up their ceremonial keys at the LA Auto Show on Wednesday. "For us, it's about being at the cutting edge of change," says Marianne Ellis. "It's a chance to support environmental causes and clean energy, while showing it's possible to make a car like this part of your lifestyle." The Mirai will go on sale in California in the fall of 2015. Read more in the press release below. The salaries for 6,500 full-time employees at Tesla's Gigafactory battery production facility have been reported. According to the Reno Gazette-Journal, the 4,550 production associates and 200 material handlers will be paid $22.79 an hour. 460 equipment technicians and 360 quality technicians will get $27.88 an hour. 930 engineers and senior staff will earn $41.83, or $87,000 a year. Tesla plans to staff 6,500 people at the Reno, Nevada-based Gigafactory by 2020. Read more at the Reno Gazette-Journal or at Teslarati. The National Biodiesel Board (NBB) has elected its governing board members. The board leaders include Sprague Operating Resources Chairman Steven J. Levy, Minnesota Soybean Processors Vice Chair Ron Marr, American Soybean Association Treasurer Mike Cunningham and Nebraska Soybean Board Secretary Greg Anderson. NBB also filled four more spots on the board, discussed federal policies, began program planning and recognized outstanding member involvement in the biodiesel industry.

The DOE calls electrolysis, photoelectrochemical, biological and solar-thermochemical key areas of hydrogen production and has made advances in each. The DOE is looking into technological advancements in making the clean fuel and ways to reduce production costs. The DOE has also outlined various plans for the 2015 fiscal year with regard to advancing hydrogen technology, with the goal of getting hydrogen prices in line with other fuels.

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.
