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.

Hyundai details its five Super Bowl ads, Santa Fe is MVP [w/video]

If the Super Bowl were Las Vegas, Hyundai would be considered one of its whales. The South Korean automaker will be advertising for the sixth straight year during The Big Game, and this time it's rolling up with five spots, four of them new. The new 2013 Santa Fe gets the star treatment, featuring in three of the spots, but the theme throughout is using "a Hyundai vehicle as the ultimate sidekick and partner-in-fun."
The four brand new commercials are:
Epic PlayDate - the headliner, uses the Santa Fe for "an unforgettable and epic play date" and features a brand new song from "a legendary alternative rock band."

Recharge Wrap-up: Uber app for Apple Watch, Hyundai brings ix35 Fuel Cell to Australia

Uber has updated its app to support the upcoming Apple Watch. Users will be able to hail a car with a single tap directly from the wearable device. The Uber app for the Apple Watch will also let the user check on the driver's progress. The Apple Watch launches on April 24. Read more at iPhone Hacks. The Place at Terracina in Austin, Texas will offer Car2go services onsite. Through a partnership with real estate group MC Companies, the carsharing service will have six dedicated parking spots at the community's entrance for residents and other nearby users. "We know our residents will benefit from the Car2Go service and hope it helps them share the good life with others," says MC Companies Vice President of Marketing Eric Brown. Read more in the press release from MC Companies below. Hyundai has debuted the ix35 (Tucson) Fuel Cell in Australia. Along with giving Australia its first hydrogen vehicle, Hyundai is also unveiling a solar hydrogen refueler. The refueling station, located at Hyundai's Sydney headquarters, uses solar power to run the electrolyzer to make hydrogen from water onsite. Hyundai's Bill Thomas told 3AW that a future where most vehicles on the road are powered by hydrogen is "a way off. We're working on our next-generation fuel cell vehicle which we're hoping to bring out in 2018, but even at that stage, we're only talking in small numbers."

MC Companies Partners with Car2Go Brings Innovative Service to The Place at Terracina with Car2Go SCOTTSDALE, Ariz., March 31, 2015 /PRNewswire/ -- Cars are a costly investment. We can't all buy our own and we understand that life can get in the way of being financially stable enough to purchase one. Living expenses, bills and unexpected costs pop up all the time. Car 2 Go is making it easy to have access to a car no matter what life throws at you. MC Companies is teaming up with Car2Go to bring this convenient service to The Place at Terracina. Car2Go now has six spaces for cars to be dropped off and picked up at the entrance of the community and this is the furthest North location that Car2Go has in the city. This provides residents, and people in the area, with shared vehicles to help them navigate through their days with ease.
