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 FCV Concept comes one step closer to reality

When Toyota first conceptualized a gasoline-electric hybrid vehicle for mainstream Americans to drive, the initial response was pretty skeptical. Still, through relentless engineering and solid product after solid product, Toyota has built the Prius brand into the dominant force in the hybrid car market.
Something like that plan of attack is what the Japanese company is preparing for hydrogen fuel cell vehicles, as well, and that attack is seeing a critical salvo fired today with the debut of this FCV Concept at the Tokyo Motor Show.
Though there's nothing substantive to be said about rumors of a 300-mile range or a sticker price around $50,000, the FCV concept does offer a few technical details. The sharp-beaked concept makes use of two high-pressure hydrogen tanks and boasts a power output density of three kilowatts per liter.

The ugly economics of green vehicles

It's fair to say that most consumers would prefer a green vehicle, one that has a lower impact on the environment and goes easy on costly fuel (in all senses of the term). The problem is that most people can't – or won't – pay the price premium or put up with the compromises today's green cars demand. We're not all "cashed-up greenies." In 2013, the average selling price of a new vehicle was $32,086. The truth is that most Americans can't afford a new car, green or not. In 2013, the average selling price of a new vehicle was $32,086. According to a recent Federal Reserve study, the median income for American families was $46,700 in 2013, a five-percent decline from $49,000 in 2010. While $32,000 for a car may not sound like a lot to some, it's about $630 a month financing for 48 months, assuming the buyer can come up with a $6,400 down payment. And that doesn't include gas, insurance, taxes, maintenance and all the rest. It's no wonder that a recent study showed that the average family could afford a new car in only one of 25 major US cities. AutoTrader conducted a recent survey of 1,900 millennials (those born between 1980 and 2000) about their new and used car buying habits. Isabelle Helms, AutoTrader's vice president of research, said millennials are "big on small" vehicles, which tend to be more affordable. Millennials also yearn for alternative-powered vehicles, but "they generally can't afford them." When it comes to the actual behavior of consumers, the operative word is "affordable," not "green." In 2012, US new car sales rose to 14.5 million. But according to Manheim Research, at 40.5 million units, used car sales were almost three times as great. While the days of the smoke-belching beater are mostly gone, it's a safe bet that the used cars are far less green in terms of gas mileage, emissions, new technology, etc., than new ones. Who Pays the Freight? Green cars, particularly alternative-fuel green cars, cost more than their conventional gas-powered siblings. A previous article discussed how escalating costs and limited utility drove me away from leasing a hydrogen fuel cell-powered Hyundai Tucson, which at $50,000, was nearly twice the cost of the equivalent gas-powered version. In Hyundai's defense, it's fair to ask who should pay the costs of developing and implementing new technology vehicles and the infrastructure to support them.
