There is a Right Option to Speak about Car Batteries And There's One other Way...

The more common is pyrometallurgy, in which recyclers first mechanically shred the cell and then burn it, leaving a charred mass of plastic, metals, and glues. Pyrometallurgy, for example, doesn't require the recycler to know the battery's design or composition, or even whether it is completely discharged, in order to move ahead safely. One is making sure manufacturers label their batteries, so recyclers know what kind of cell they are dealing with-and whether the cathode metals have any value. If the last few pages of technical information made your head spin, we have a treat for you -- the next page has another lust-worthy Bluetooth-enabled bauble that'll make you even dizzier. The alternating current they produce has a very square wave, which is fine if you just want to make coffee or run something with a simple electric motor. Both processes produce extensive waste and emit greenhouse gases, studies have found. That's just one of the many problems confronting researchers, including Thompson, who are trying to tackle an emerging problem: how to recycle the millions of electric vehicle (EV) batteries that manufacturers expect to produce over the next few decades. Current EV batteries "are really not designed to be recycled," says Thompson, a research fellow at the Faraday Institution, a research center focused on battery issues in the United Kingdom. Gaines says. Hydrometallurgy, in contrast, involves dunking battery materials in pools of acid, producing a metal-laden soup. Hydrometallurgy can extract materials not easily obtained through burning, but it can involve chemicals that pose health risks. And the business model can be shaky: Most operations depend on selling recovered cobalt to stay in business, but batterymakers are trying to shift away from that relatively expensive metal. Now, recyclers primarily target metals in the cathode, such as cobalt and nickel, that fetch high prices. And recovering the desired elements from the chemical soup can be difficult, although researchers are experimenting with compounds that promise to dissolve certain battery metals but leave others in a solid form, making them easier to recover. Nissan's rectangular Leaf battery module can take 2 hours to dismantle. In direct recycling, workers would first vacuum away the electrolyte and shred battery cells. If it ends up in a landfill, its cells can release problematic toxins, including heavy metals. A quick visual check of the belt for cracking, excessive wear, and other age issues can give an indication of a future problem. Given the rapidly changing battery market, Gaines notes, cathodes manufactured today might not be able to find a future buyer. National Renewable Energy Laboratory have built economic models showing the technique could, if scaled up under the right conditions, be viable in the future. As the EV industry ramps up, the need for progress is becoming urgent, says Linda Gaines, who works on battery recycling at DOE's Argonne National Laboratory. Governments are inching toward requiring some level of recycling. While this fear is understandable, given our experience with phone and laptop batteries losing capacity faster than we’d like, EV batteries are designed and built to be far more resilient. There's a copy by the phone. And recycling the battery can be a hazardous business, warns materials scientist Dana Thompson of the University of Leicester. So far, direct recycling experiments have only focused on single cells and yielded just tens of grams of cathode powders. Electric cars have several benefits when replacing ICE cars, including a significant reduction of local air pollution, as they do not emit exhaust pollutants such as volatile organic compounds, hydrocarbons, carbon monoxide, ozone, lead, and various oxides of nitrogen. The amount varies widely based on how local power is generated, e.g., using coal or natural gas, which emit carbon pollution, versus renewable resources like wind or solar, which do not. Or a car produced for over 65 years like the Beetle was (the last rolled off the production line in 2003 in Mexico)? Toyota announced that 90 out of the 100 vehicles produced globally will be placed in carsharing demonstration projects in the United States and the rest in Japan. Several carmakers have said they plan to phase out combustion engines within a few decades, and industry analysts predict at least 145 million EVs will be on the road by 2030, up from just 11 million last year. That's attractive to batterymakers because recycled cathodes wouldn't require heavy processing, Gaines notes (although manufacturers might still have to revitalize cathodes by adding small amounts of lithium). But because of the small quantities, the metals are like needles in a haystack: hard to find and recover.
