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's Texas move could boost state's economy by $7.2B in 10 years

They say everything is bigger in Texas, and apparently that includes the Toyota's effect on the economy. The giant Japanese automaker's new headquarters in Plano, TX, will add an estimated $7.2 billion to the state over the next 10 years, according to a new study commissioned by the city and cited by Bloomberg.
The benefits appear to be an absolute steal compared to the direct incentives that Plano and the state are giving Toyota. The report finds that by the time the automaker's campus is complete in 2018, it could have 3,650 full-time workers there at an average salary of $104,000. The city has prepared $6.75 million in grants, plus property tax discounts, according to Bloomberg. In addition to that, the state is offering the business $40 million in incentives from its Texas Enterprise Fund. This is still a fraction of what Toyota is estimated to bring in.
Toyota announced in April that it would move its US operations to Plano after being headquartered in California since 1957. The move affects thousands of employees from the sales and engineering divisions. The first workers will arrive there this fall, but Toyota will eventually have a whole campus in Plano by late 2017. The move is expected to save it huge amounts in taxation and offer employees a lower cost of living. Toyota North America CEO Jim Lentz also says that the Texas location puts the headquarters closer to more of the business' factories in the south. Texas certainly appears to be showing it some southern hospitality.

Toyota sold a million hybrids in last nine months, 6M since 1997

Toyota's first hybrid model – the Prius – went on sale in 1997 in Japan. It took 14 years for the company to see a cumulative total of three million hybrids (a mark reached in March 2011). Today, Toyota announced that its global sales figures of all of its gas-electric models (and there are a lot of them now, including ones we've barely heard of here in the US, like the Crown Majesta or the Harrier Hybrid) have reached six million. Toyota calculates that all those hybrids have saved 41 million tons of CO2 emissions from entering the atmosphere. Toyota's ever-increasing hybrid sales pace means the company sold as many in the last three years as it did in the first fourteen. As you can see in our chart, the trendline shows that we'll hit the next-million mark in short order. In fact, Toyota says that it sold a million hybrids in the last nine months, the shortest time it has ever taken the automaker to sell that many hybrids. Part of the reason is that there are 24 hybrid Toyota and Lexus models available around the world, and Toyota says another 15 will be coming in the next two years. Anyone want to guess when Toyota will hit seven million? August? Worldwide Sales of Toyota Hybrids Top 6 Million Units Toyota City, Japan, January 15, 2014-Toyota Motor Corporation announces that cumulative global sales of its hybrid vehicles topped the 6 million unit mark as of December 31, 2013, reaching 6.072 million units1. The latest million-unit milestone was achieved in the fastest time yet for Toyota, taking just nine months. Helping mitigate the environmental effects of vehicles is a priority at Toyota. Based on its belief that environment-friendly vehicles can only truly have a positive impact if they are widely used, Toyota has endeavored to encourage the mass-market adoption of hybrid vehicles. As of this month, Toyota sells 24 hybrid passenger car models and one plug-in hybrid model in approximately 80 countries and regions around the world. Furthermore, within the next two years, Toyota will launch a total of 15 new hybrid vehicles worldwide, including the new "Harrier Hybrid" in Japan on January 15 and the new "Highlander Hybrid" in the United States in the near future. Toyota will continue augmenting its product lineup even further and increasing the number of countries and regions where it sells hybrid vehicles.
