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 urges owners of old Corolla, Matrix and RAV4 models to park them until airbags are replaced

DETROIT — Toyota and General Motors are telling the owners of about 61,000 older Corolla, RAV4, Matrix/ Pontiac Vibe models to stop driving them because their Takata airbag inflators are at risk of exploding and hurling shrapnel. The urgent warning Monday covers: Certain Corolla compact cars and Matrix hatchbacks from the 2003 and 2004 model years. RAV4 small SUVs from 2004 and 2005. Also covered are about 11,000 Pontiac Vibes from 2003 and 2004, which are essentially the same as the Matrix and were made at the same California factory. Most of the vehicles are in the U.S. “If the airbag deploys, a part inside is more likely to explode and shoot sharp metal fragments, which could cause serious injury or death to the driver or passengers,” Toyota said in a statement. Owners can go to nhtsa.gov/recalls and enter their 17-digit vehicle identification number to see if their cars are affected. If you're not the original owner of the vehicle, the manufacturer's recall letter might not reach you, so be sure to do the VIN check. The recalled RAV4s have Takata driver's airbags while the Corolla and Matrix models have them on the passenger side. The Corolla and Matrix also are under a separate recall because their airbags can be deployed without a crash, the company said. Both companies said owners should contact a local dealer instead of driving the cars in for repairs. Dealers will provide options such as mobile repair, towing the car to a dealer, or vehicle pickup and delivery. Takata used volatile ammonium nitrate to create a small explosion to inflate airbags in a crash. But the chemical propellant can deteriorate over time when exposed to high temperatures and humidity. It can explode with too much force, blowing apart a metal canister and spewing shrapnel. At least 26 people have been killed in the U.S. by Takata inflators since May 2009, and at least 30 have died worldwide including people in Malaysia and Australia. In addition, about 400 people have been injured. The exploding airbags sent Takata of Japan into bankruptcy. The potential for a dangerous malfunction led to the largest series of auto recalls in U.S. history. About 100 million inflators were recalled worldwide. Recalls Pontiac Toyota Takata airbag recall

Camry, Avalon Hybrids involved in stop-sale of 50,000 Toyota vehicles

A number of popular Toyota vehicles can currently not be sold thanks to something called a "stop-sale" order. The reason is that the seat heater on these vehicles - which include the 2013 and 2014 Camry, Camry Hybrid, Avalon, Avalon Hybrid, Sienna, Corolla, Tacoma and Tundra models - "does not meet a provision of US Federal Motor Vehicle Safety Standards (FMVSS) requiring materials to retard flame at a specified rate." In other words, the seat heater could burn too fast. There have been no reports of fires or injuries due to the issue. Toyota told AutoblogGreen that around 50,000 vehicles are affected. No Scion or Lexus vehicles have the problem. The exact fix has not been identified, but Toyota said it is preparing a modification for all vehicles still on dealer lots, but there has not yet been an official recall. Instead, Toyota filed a "Non-Compliance Information Report" with the National Highway Traffic Safety Administration (NHTSA) today. You can read Toyota's official statement below. Toyota and NHTSA are also looking at around 30,000 2007-2008 model year Camry Hybrids for brake issues. Seat Heater Non-Compliance Issue Creates Temporary Stop Sale On Certain Toyota Models January 30, 2014 Toyota has informed the National Highway Traffic Safety Administration (NHTSA) that it has initiated a stop sale of certain Avalon, Avalon Hybrid, Camry, Camry Hybrid, Corolla, Sienna, Tacoma and Tundra vehicles equipped with seat heaters in order to address a non-compliance issue. In involved vehicles, the seat heater, which is a small portion of the soft materials of the seat assembly, does not meet a provision of U.S. Federal Motor Vehicle Safety Standards (FMVSS) requiring materials to retard flame at a specified rate. Toyota is preparing a modification for this condition, which will be implemented on all covered vehicles in dealer inventory. There have been no reports globally of any related incidents in the field with units in operation. Per NHTSA regulations, Toyota will file a Non-Compliance Information Report today.
