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 crashes two Sonatas in public to prove a point about safety

According to The Korean Car Blog, Hyundai has a quality perception gap in the minds of its domestic customers, but it's not with another brand: some South Koreans think US-market Hyundai products are safer than those sold in South Korea. For example, home-market consumers think the US gets more advanced airbag systems than they do. Hyundai decided that the best way to combat that idea was to ram two 2015 Sonata 2.0 Turbos into one another, each one traveling at 34 miles per hour, in front of a live audience. From what we can glean from a Google-translated version of the backstory, the company had a local university professor secure two vehicles, a Lakeside Blue model from South Korea and a Venetian Red model manufactured in the company's US plant and flown over. It invited buyers of the 30th Anniversary Sonata and members of the local media to a drive-in movie premiere on August 22, the show actually being the crash test. In addition to the two Sonatas that would autonomously throw themselves at one another, the company had a Tucson Fuel Cell use its hydrogen fuel cell stack to make popcorn and 119 various emergency vehicles emergency services on standby in case anything went wrong. When guests were asked which car they thought would fare better, 74 percent of the crowd said the US-spec car. In interviews conducted on the street, 81 percent of respondents said they believe the US car is safer. The video above is in Korean, but car crashes are a universal language.

Honda scores big in Automobile Advertising of the Year Awards [w/videos]

This year the Detroit Auto Show didn't just celebrate the automobile, it celebrated how we find out about the automobile, too. Partnering The One Club, this year introduced the 2014 One Show Automobile Advertising of the Year Award to Cobo Hall, celebrating winners in five different categories of advertising: broadcast television, online, interactive, experiential, and print/outdoor. Winners in those categories were judged by 50 creative directors and journalists, while a Public Choice category was chosen from among nearly 20,000 online votes.
Honda walked off with three of the six awards, its Hands spot taking Broadcast honors, its Sound of Honda getting the Online category and Illusions winning Public Choice. Hyundai made the grade in Interactive with Driveway Decision Maker, Fiat captured Print/Outdoor with its "Letters" ad, and Toyota's Tundra Endeavor Campaign spot and BMW's A Window into the Near Future were co-winners for Experiential.
You can watch all of the press release and winning videos below or check out all of the finalists, announced last month, for a refresher.
