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.

Next Lotus Elise to draw from its roots

Recently-appointed Lotus CEO Jean-Marc Gales told Autocar that work on the new Lotus Elise, which is coming in 2020, is already underway, and thanks to growing sales, the automaker is set to make a profit for the first time in 20 years. Gales also dropped some details about the new sports cars' design philosophy and underpinnings. According to the report, the new Elise will utilize the same aluminum chassis technology found in the original Elise and won't bear any resemblance to the 2010 Elise concept. Instead, the upcoming vehicle will uphold its roots with a lightweight design that emphasizes driver involvement at an affordable price. The new Elise is rumored to weigh in at roughly 1,984 pounds, almost 384 pounds more than the original Elise. In order to meet US crash ratings, the Elise will most likely be wider, but have the same length as the current model. Power will probably come from a Toyota unit producing between 134 horsepower and 245 horsepower. The Elise is expected to come to the US where it will be offered with a manual and automatic transmission, which will both come from Toyota as well. Gales claims Lotus has more orders now than in any year in the last 10 years, with the US being one of the automaker's most important markets. Related Video:

Lexus GX, Toyota Land Cruiser Prado facelifts leaked

The Lexus GX and the Toyota Land Cruiser Prado, which isn't sold in the US, have gone without visual updates since the current generation was launched in 2009. But what appear to be patent filing sketches and pictures of the sibling sports utility vehicles' mid-cycle updates have been leaked on a Russian Land Cruiser Club forum.
Major changes to the GX's front end will be made to incorporate Lexus' signature grille. Gone are the awkwardly shaped headlamps and the soft-looking triple-slat grille. The sketch shows the Lexus with a new bumper, lower-profile headlights and a more aggressive, angular grille with one more slat and a gaping lower air-intake opening. The vehicle's profile looks unchanged, but the rear bumper will be reshaped slightly to fit new, better-integrated horizontal reflectors.
The Toyota gets a handful of styling updates as well, including a new front bumper with higher-profile headlamps that look a bit out of place to us. The Prado's profile also looks unchanged, but the rear end gets restyled taillights and a reshaped license-plate enclosure.
