Toyota reveals Tokyo Motor Show concepts

Toyota is getting ready for the Tokyo Motor Show later this month, and to tease us, the Japanese automaker has released photos and information about the concept vehicles it'll be bringing to the show. In all, there'll be five world premieres from Toyota (six if you split the Voxy and Noah minivan concepts), including some vehicles that'll be released in the near future, and others that need more time to incubate.
Let's get the world premieres out first. Toyota is a pioneer of gasoline-electric hybrids, but it's also pursuing hydrogen fuel cell-powered vehicles. The clearest indication of this is the FCV concept, a hydrogen-powered sedan in the same vein as the the FCV-R that will bow at the auto show. (Read more about the FCV, here.)
Other world debuts include the FV2 concept (pictured), a unique, one-seat future vehicle that emphasizes the "Fun to Drive" philosophy; the JPN TAXI concept, a next-generation taxi concept designed with Japanese hospitality in mind; and the Voxy and Noah concepts, next-generation minivans that differ most in exterior design cues and are scheduled to launch in the Japanese market in early 2014.

Toyota reveals new customizable Camatte57s kid-friendly concepts

Toyota plans to follow up last year's kid-friendly Camatte concept with two new versions: the Camatte57s and Camatte57s Sport (right). Like the original Camatte, the two new concepts will make their debut at the International Tokyo Toy Show, which is happening this weekend.
Not much has changed with these two new Camatte models. Like their predecessor, they both feature detachable body panels (the count is up to 57), a 1+2 seating array and reconfigurable pedals that allow children to operate the gas and brakes while Mom or Dad steers. What is new is an open-top roadster design that even eschews doors in favor of easier ingress/egress. They look like something a tourist would rent to get around a Hawaiian island, though we dig the distinct personalities of each model's design.
Both cars are all-electric, though Toyota hasn't provided any other specifications, like what makes the Sport model sporty besides its more aggressive body panels and silver, black and red color scheme. That's just as well, as neither concept, like the original Camatte before them, is street legal.

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.
