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.

Toyota releases its Le Mans recap, 'The Ultimate Endurance Race'

Two weeks ago, Audi released its short video about this years 24 Hours of Le Mans, and now Toyota has put the experience into its own words and pictures. Called The Ultimate Endurance Race, the clip and accompanying press release focus on how hybrid power helped Toyota claim second and fourth places with the TS030 Hybrid in just its second year competing at Le Mans.
There are some brief scenes of the battles had this year, like when Lucas di Grassi in the Toyota almost kissed Allan McNish in the Audi above, but the best part might be when Toyota promises it will be back. Next year, it's gonna be good. You'll find the relevant words and the images just below.

2020 Ford Escape plug-in vs. Toyota RAV4 Prime, Mitsubishi Outlander PHEV: How they compare on paper

This year is when the entry-level plug-in crossover market really starts to heat up. Both Ford and Toyota have new models in the 2020 Ford Escape and the 2021 Toyota RAV4 Prime. They join the segment veteran Mitsubishi Outlander PHEV, which has been available in the U.S. since the 2018 model year. And of course that means it's time to look at how the numbers add up while we wait for our chance to drive the new competitors. You can find a chart with all the details immediately below, followed by more detailed analysis. Powertrain One of the key factors for any hybrid, particularly plug-in models, is how little fuel they use. Overall, the Ford Escape is the winner with 100 mpg-e, the fuel economy equivalency for the vehicle when assessing it with a full battery. The Toyota is close behind with 94 mpg-e. We're expecting the Escape to also be a bit more efficient when running only on gas, as it reportedly gets 41 mpg. The RAV4 will likely get 40 mpg, or possibly slightly less, since the non-plug-in RAV4 Hybrid achieves 40 mpg combined. Running solely on electric power, though, the RAV4 edges out the Escape with 42 miles of range versus 37. Behind both of them is the Mitsubishi with just 22 miles of range, 25 mpg on gasoline only, and 74 mpg-e with a full battery. One unique feature the Mitsubishi claims is DC fast charging capability, meaning 80% of its electric range can be restored in just 25 minutes, possibly allowing for more electric use depending on where you're driving it. While fuel economy is a priority for hybrids, customers won't want to compromise on other features. The Toyota is easily the least compromising, as it returns impressive range and efficiency while also providing a whopping 302 horsepower and all-wheel drive. The Mitsubishi also has all-wheel drive, but a comparatively paltry 190 horsepower. The Ford produces slightly more power at 200, but is front-wheel-drive only. While low in comparison to the RAV4 Prime, the Mitsubishi and Ford have very competitive output to many comparably-sized conventional crossovers with base engines, such as the Honda CR-V, Chevy Equinox and others. Size and space Naturally one of the reasons for buying a crossover is for its practical shape for comfortable hauling of people and stuff. In this regard, all three crossovers are very close. The Escape wins out with legroom, the Toyota with shoulder room. Headroom is split between the Toyota and Mitsubishi.
