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.

2020 Toyota Highlander vs other 3-row crossovers: There can only be one!

We've done quite a few spec comparison posts involving three-row family crossovers, and when included, the Toyota Highlander has always been the runt of the group. While the rest increasingly seemed to be benchmarking each other toward greater girth, the Highlander was the outlier.  That changes a bit for the 2020 Toyota Highlander, but only a bit. It's now larger and more competitive, specifically in regards to the amount of cargo space aft of the third-row seat. As you can see below, this aligns the Highlander most closely to its long-time competitor the 2020 Honda Pilot. However, let's see how it stacks up to others in the segment, which is heavily populated now, so for the sake of space, we've selected the newest entries: Kia Telluride, Hyundai Palisade, Subaru Ascent and Ford Explorer. The order in which they are presented is random.  Performance and fuel economy The 2020 Highlander is more than 200 pounds lighter than its predecessor, but has the same 295-horsepower V6 engine that was already one of the strongest in the segment. We'd say that would give it a leg up, but the Pilot and Explorer have proven to be sprinters, delivering 0-60 times in the low-6 range by some publications' stopwatches (or VBoxes, whatever). We don't expect the Highlander to beat them, but it may dip into the 6's. The heavy, less-powerful Subaru Ascent is most likely to take up the rear. It's fuel economy of 23 mpg combined also matches the Highlander and Explorer for segment-best. Remember, however, that the Explorer's turbocharged inline-four engine is likely more susceptible to differences in driving style (read: a heavy foot).  Of course, if you're really interested in fuel economy, the Highlander and Explorer are the only vehicles in the segment to offer hybrid versions. The Ford Explorer Hybrid puts a greater emphasis on performance, however, resulting in lower estimates of 25 mpg combined (AWD) and 28 mpg combined (FWD). By contrast, the new 2020 Toyota Highlander Hybrid is estimated to return 36 mpg combined.  Passenger and cargo space According to Highlander chief engineer Yoshikazu Saeki, he had a choice of two directions with the new Highlander. He could have indeed made it bigger, matching these very competitors, especially in terms of third-row and cargo space. Or, he could have maintained a smaller-than-average size. He obviously chose the latter. First, it was the size customers had come to expect. Would they be put off by something bigger?
