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 adds tech to Blue Link, offers it free for 3 years

Hyundai has not only thrown more technology at its 2018 lineup, the tech will be less expensive. At the New York Auto Show, the South Korean automaker announced that Blue Link remote services will be free for three years on the 2017 Ioniq and on all 2018 models, starting with the Sonata, Elantra GT, and Santa Fe Sport. The remote services include all three packages currently offered as options with a Blue Link subscription: Connected Care, Remote, and Guidance. Among the included features are automatic collision notification, a monthly vehicle health report, remote lock and unlock, stolen vehicle recovery assistance, and remote start with climate control. That last function gets an update for 2018 that allows control of the rear defroster and heated side mirrors on the coming Sonata and Elantra GT. The whole shebang tallies 10 features in the Connected Care Package, 12 features in the Remote Package, and 3 features in the Guidance Package. But wait, there's more: the SD-card-based navigation maps get free downloads for three years. Blue Link subscribers can already access remote functions with a smartphone and a smartwatch. For 2018, Amazon Alexa (via the Tap, Echo, and Echo Dot) and Google Assistant (via the Google Home speaker) become control devices. You can tell either gadget to start your car and set the climate control, to send an address to the navigation system, or start and stop the charging of an Ioniq. Right now, if a new buyer subscribes to Blue Link, he gets three free months of the Remote and Guidance packages, and a free year of the Connected Care Package. After the trial, each package costs $99 per year. By offering the packages free for three years, Hyundai dangles a savings of nearly $750 in front of those who can wait for the new models. Be sure to read this accompanying post about the Sonata's design. Related Video:

2015 Hyundai Sonata configurator powers up

Eager to get your hands on a new Hyundai Sonata? We could hardly blame you. With more mature styling and better equipment for less than the model that preceded it, the new Sonata makes a compelling case, even in a market segment this competitive that includes such rivals as the Nissan Altima, Toyota Camry, Honda Accord, Mazda6, Ford Fusion, Chevy Malibu, Chrysler 200, Volkswagen Passat and Kia Optima.
The first units are just arriving at dealers now, but if your local showroom doesn't have one for you to check out just yet, we've got good news for you as Hyundai has just launched the car's online configurator. The system lets you choose from four trim levels, nine exterior colors, a couple of equipment packages and an assortment of accessories to make your Sonata yours.
Pictured here is the top-of-the-line Sonata Sport 2.0T that starts at $29,385 (inclusive of delivery), but the base Sonata starts under $22k. Spec yours (or any new Hyundai, for that matter) in the online configurator linked here.
