VW quite interested in solid-state batteries for EVs

Volkswagen is about to make a decision about which advanced battery technology the automaker will seriously investigate to give its electric vehicles more range. VW will decide by July if it will use solid-state batteries made by US-based QuantumScape Corp. in future EVs, according to Bloomberg News. Last year, VW bought a five-percent stake in QuantumScape, which was founded by ex-Stanford University researchers. The lure is that QuantumScape's solid-state batteries may provide a single-charge range of as long as 430 miles. That's more than three times the current range of the VW e-Golf electric vehicle the company recently started selling to the public and is substantially longer than the single-charge range of the Tesla Model S electric sedan. The batteries are also fireproof, making VW's potential decision one with an eye towards more vehicle safety. Solid-state battery technology, in which solid lithium electrodes are used instead of liquid electrodes such as those in lithium-ion batteries, are the subject of research at other automakers and suppliers as well. Toyota says they could be here by 2020. Recently, the cordless vacuum cleaner maker Dyson acquired a $15-million equity stake in Michigan-based battery maker Sakti3 with the idea of using the startup's solid-state batteries in its products. General Motors also has a minority stake in Sakti3, which was spun off from the University of Michigan.

Brand new cars are being sold with defective Takata airbags

If you just bought a 2016 Audi TT, 2017 Audi R8, 2016–17 Mitsubishi i-MiEV, or 2016 Volkswagen CC, we have some unsettling news for you. A report provided to a US Senate committee that oversees the US National Highway Traffic Safety Administration (NHTSA) and reported on by Automotive News claims these vehicles were sold with defective Takata airbags. And it gets worse. Toyota and FCA are called out in the report for continuing to build vehicles that will need to be recalled down the line for the same issue. That's not all. The report also states that of the airbags that have been replaced already in the Takata recall campaign, 2.1 million will need to eventually be replaced again. They don't have the drying agent that prevents the degradation of the ammonium nitrate, which can lead to explosions that can destroy the airbag housing and propel metal fragments at occupants. So these airbags are out there already. We're not done yet. There's also a stockpile of about 580,000 airbags waiting to be installed in cars coming in to have their defective airbags replaced. These 580k airbags also don't have the drying agent. They'll need to be replaced down the road, too. A new vehicle with a defective Takata airbag should be safe to drive, but that margin of safety decreases with time. If all this has you spinning around in a frustrated, agitated mess, there's a silver lining that is better than it sounds. So take a breath, run your fingers through your hair, and read on. Our best evidence right now demonstrates that defective Takata airbags – those without the drying agent that prevents humidity from degrading the ammonium nitrate propellant – aren't dangerous yet. It takes a long period of time combined with high humidity for them to reach the point where they can rupture their housing and cause serious injury. It's a matter of years, not days. So a new vehicle with a defective Takata airbag should be safe to drive, but that margin of safety decreases with time – and six years seems to be about as early as the degradation happens in the worst possible scenario. All this is small comfort for the millions of people who just realized their brand-new car has a time bomb installed in the wheel or dashboard, or the owners who waited patiently to have their airbags replaced only to discover that the new airbag is probably defective in the same way (although newer and safer!) as the old one.
