Getting from here to there is becoming increasingly more sustainable, in part, by electric cars.“All the cars are getting electrified,” Don Hillebrand, with the Advanced Powertrain Research Facility at Argonne National Labs in Illinois, said. “The minivan and the middle of the road sort of cars and the trucks.”By 2040, more than half of new car sales and a third of all cars on the road across the world are projected to be electric, according to Bloomberg.com.But it raises an important question.“What do you do with these batteries at the end of their life?” Linda Gaines said. Gaines is the chief scientist for Recell Center of Advanced Battery Recycling.“For a long time a lot of us looked at electrification sort of as hype,” Hillebrand explained.Hillebrand works at Argonne National Labs in the energy systems division, focusing on optimizing how energy is used. He sees one big problem in the creation of electric car batteries. “There are not enough fundamental elements that go into batteries for us to make all the batteries we need forever and throw them away when we’re done,” he said.Meaning these elements need to be reused. “The early batteries from 10 years ago are hitting the end of their life,” he said.The global stockpile of these batteries is expected to exceed 3.4 million by 2035, compared to 55,000 in 3018, according to the Institute for Energy Research. Once the battery loses 20 to 30 percent of its capacity, the available driving range gets shorter, so some companies are using them for other purposes.Florida Power and Light is using them for power storage, and Nissan is reusing old Leaf batteries to power Japanese street lights.These companies are repurposing, but researchers think another fix could come in the development stage.“After 10, 15 years, those batteries are going to reach the end of life and we have to do something with them,” Venkat Srinivasan, a battery scientist at Argonne National Labs, said. “We think there are ways in which we can make these batteries last more than 20 years.”And that’s exactly what’s being done inside this facility. The lab he works in is looking into ways to make batteries last longer. But for now, the main focus is on giving them a second life by recycling.“The biggest challenge today in recycling batteries is they’re not economic,” Venkat said.That's where the Recell Battery recycling center and other recycling businesses come into play.“If you can recover the materials in the battery in a usable form,” Linda Gaines explained. “You can actually recover valuable product.” This includes cobalt and other elements. Linda Gaines and Jeff Spangenberger are part of this center. Their goal is to come up with a recycling process that’s profitable.“Some things take more energy and resources to recycle then it did to make them in the first place,” Gaines said. “So, when you’re looking at the whole life cycle of the product, you need to try to figure out what the benefits are and what the costs are to recycle.”To understand size, one pouch cell in an electric car battery is about the size of a tablet. In the generation 1 Chevy Volt there are 288 pouch cells in one battery.Cars have become the biggest user of lithium ion batteries -- even more than consumer electronics, the Institute for Energy Research said.While Recell is looking into ways to make the recycling process more beneficial and profitable, Larry Reaugh with American Manganese, Inc. is doing something similar. “That’s where we come in, we want the battery packs,” Reaugh said. With their process, they are able to recover the elements inside the battery, comparing their operation to a small operating mine.“There’s a lot of money in it, because it’s very valuable material,” he said.As more batteries retire, companies like this will become more important.“There’s a trickle of batteries that are being recycled right now, but there’s gonna be an avalanche of batteries coming in the next 5 to 10 years as cars hit the end of their life,” Hillebrand said. 4027

If it weren’t for the never ending Fake News about me, and with all that I have done (more than any other President in the first 2 1/2 years!), I would be leading the “Partners” of the LameStream Media by 20 points. Sorry, but true!— Donald J. Trump (@realDonaldTrump) September 11, 2019 299

Federal Reserve Chairman Jerome Powell says he would not resign if pressured to do so by President Donald Trump."No," Powell answered simply, when asked Friday morning during a panel at the annual American Economics Association conference alongside former Fed chairs Janet Yellen and Ben Bernanke.Trump has repeatedly criticized Powell for continuing to tighten monetary policy, saying on Twitter that it's the "only problem" with the economy.It's unclear whether presidents legally can fire Fed chairs, who they appoint for four-year terms.Powell said Trump had not directly expressed dissatisfaction to him.Powell added that he has no meeting scheduled with Trump. White House aides had floated the idea of inviting the former investment banker to sit with the President in person to allay Trump's concerns."Meetings between presidents and fed chairs do happen, but nothing's been scheduled," Powell told moderator Neil Irwin, an economics reporter for the New York Times. 986

  

For the second time this week, a deadly shooting unfolded at a US Navy base Friday when a gunman killed at least three people and injured several others at Naval Air Station Pensacola in Florida.The suspected shooter, who was also killed, was a member of the Saudi Arabian military training at the station, according to five US defense officials and another person familiar with the investigation.Investigators are looking into whether the shooting was terror-related as a possible motive, but it's still early in the investigation.CNN has reached out to the Saudi Embassy in the US and has not heard back.The shooter was killed after two deputies exchanged gunfire with him, Escambia County Sheriff David Morgan told reporters in a news conference.The FBI has taken over the investigation, according to an FBI spokeswoman.Eight people were taken to Baptist Health Care, including one who died, said Chief Deputy Chip Simmons. The deputies who confronted the shooter also suffered gunshot wounds -- one in the arm and one in the knee. Both are expected to survive.The shooting occurred in a classroom building, Commanding Officer of NAS Pensacola Capt. Tim Kinsella said. The base will remain on lockdown until further notice, he said.The names of the victims are not being released until authorities notify their families.Walking through the scene "was like being on the set of a movie," Morgan said."This doesn't happen in Escambia County. It doesn't happen in Pensacola. It doesn't happen to our friends and neighbors who are members of the US Navy," Morgan said. "But it did, and it has."The shooting comes just 1628
