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 Ioniq blends familiar cues with futuristic design

Hyundai is preparing to unveil its first dedicated electrified vehicle. Called the Ioniq, it's set to launch at the Geneva Motor Show this March. Now, the Korean automaker is giving us an idea of what to expect with a series of teaser renderings. As you can see from the first image in the slideshow above, the exterior design of the Ioniq announces the environmentally friendly powertrain at its heart. That means an aerodynamically optimized shape to cut through the wind with a minimum of interference. The greenhouse tapers off to a high tail not unlike those seen on the Toyota Prius and Chevy Volt – whose drivers Hyundai will seek to attract with this new model. The wheels also appear to adopt an aero-focused design, but signature Hyundai design traits are still evident, from the hexagonal grille to the upward kink in the C-pillar. Inside the cabin promises a forward-looking but comfortable space with simple rounded surfaces. Cool blue trim sets the mood, and screens in the instrument cluster and the center of the dashboard reduce clutter and display vital information. The manufacturer says it's using "eco-friendly materials to convey a futuristic yet warm cabin ambiance that will appeal to a new generation of motorists." The Ioniq will offer a choice of three powertrain options with varying degrees of electrification: a gasoline-electric hybrid, a plug-in hybrid, and full electric propulsion. It's rare for an automaker to offer all three choices. Most electrified vehicles come in conventional and hybrid versions (like Hyundai's own Sonata), hybrid and plug-in hybrid (like the Prius), or even plug-in or fully electric variants (like the BMW i3). Hyundai is slated to unveil the Ioniq in Korea next month ahead of its auto show tour, so watch this space for more. CLASS-LEADING AERODYNAMICS AND STRIKING DESIGN DETAILS FOR HYUNDAI MOTOR'S NEW ALTERNATIVE-FUEL IONIQ - Teaser rendering highlights eye-catching silhouette and design details - Sleek and simple exterior reduces aerodynamic drag for greater efficiency - Elegant interior combines environmentally-friendly materials and flexible space December 16, 2015 – A new rendering of Hyundai Motor's all-new IONIQ hints at how the innovative, alternative-fuel compact vehicle, which is due for launch in early 2016, will combine head-turning good looks with class-leading aerodynamic performance.

Recharge Wrap-up: Hyundai H350 Fuel Cell van, Formula E in Brooklyn

Formula E's New York City e-Prix will take place in Brooklyn. With lower Manhattan and the Statue of Liberty as its backdrop, the race will play out on a 1.21-mile, 13-turn course on the streets of Red Hook. Formula E revealed the location at a press conference at the site of the circuit, at the Brooklyn Cruise Terminal on the New York Harbor. "New York City is where technology, sustainability and commerce collide," says NYC Mayor Bill de Blasio. "We are thrilled to be the new home of the ePrix." The race is scheduled for July 29, 2017. Watch the video above, and read more from Formula E. Hyundai is debuting its H350 Fuel Cell Concept at the 2016 IAA Commercial Vehicle Show in Hannover, Germany. The hydrogen-powered commercial van offers emissions-free (except for water vapor) driving without the lengthy recharge times of a plug-in vehicle. It has a driving range of 262 miles on a single tank, and refuels in just minutes. It can be configured with a cargo area of up to 456 cubic feet, or with seating for 14 passengers. Hyundai's fuel cell van concept draws from the automaker's experience with the Tucson Fuel Cell production vehicle. Read more from Hyundai. Mercedes-Benz says it will offer an electric delivery van again in 2018. The German automaker left the niche market in 2012 after slow sales of its Vito E-Cell, which it launched in 2010. "The future of urban deliveries will be electric," says Volker Mornhinweg, head of the company's vans division. "We at Mercedes-Benz Vans are convinced of this." While Mercedes has not said whether the EV will be a new model or an electric version of a current offering, it did say it would develop the powertrain in-house, and offer various battery capacities.
