Comments Off on China will make EV manufacturers responsible for battery recycling

Electric automakers in China now have an added task beyond just manufacturing vehicles: dealing with batteries. Reuters said the country’s industry ministry put out interim rules this week holding electric vehicle (EV) manufacturers responsible for creating facilities for collecting and recycling spent batteries in an effort to address waste . Lithium battery waste could reach up to 170,000 metric tons in 2018, and China’s government is hurrying to improve recycling capabilities, according to Reuters, as the waste threatens to become a mounting pollution source. The new rules say carmakers must recover EV batteries, and set up service outlets to gather and store the devices, and transfer them to specialist recyclers.

The notice said companies should adopt measures inciting good practices among customers, like battery repurchase pacts or subsidies. EV carmakers — with battery manufacturers and sales units — also have to erect a traceability system to identify owners of batteries that were discarded. Battery makers also have another responsibility under the new rules: providing technical training for automakers to dismantle and store old batteries. They’re encouraged as well to adopt standardized designs for batteries that can be easily taken apart. China began promoting electric vehicles just under a decade ago, in 2009, according to Reuters, and aim to be a leading producer for the world. The industry could help the country restrain emissions from cars, promote technology industries, and boost energy security . How will these rules impact the EV industry in China? The answers remain to be seen — and time will tell if the new rules do indeed curb waste. Via Reuters Images via Depositphotos and Wikimedia Commons

MIT’s new carbon-free supercapacitor could revolutionize the way we store power

Comments Off on MIT’s new carbon-free supercapacitor could revolutionize the way we store power

Finding ways to store clean energy is one of the largest challenges green entrepreneurs and innovators face today. A team led by MIT researchers developed a new supercapacitor that could revolutionize the way electric vehicles , for example, store power. The MIT supercapacitor, made without conducive carbon , even has the potential to ” deliver more power .” Past supercapacitors were all made with carbon, which required “high temperatures and harsh chemicals to produce,” according to MIT News. The main innovation by the team of five MIT scientists and one Argonne National Laboratory scientist is the use of new materials, metal organic frameworks (MOFs). It was thought MOFs couldn’t conduct electricity , but the team discovered “highly electrically conducive MOFs” in the lab. Related: New graphene super batteries charge up in seconds and last virtually forever MOFs that can conduct electricity are beneficial for supercapacitors because they have an “extraordinarily large surface area for their size,” more than carbon materials possess. As supercapacitor performance is dependent on surface area, electrically conducive MOFs could be the perfect material to utilize in such devices. Plus, MOFs “can be made under much less harsh conditions” than carbon. This research is important because it could allow electric vehicles, for example, to be even more environmentally friendly and receive more power. The MIT team says their supercapacitors could also be used for grid-scale storage and “could play an important role in making renewable energy sources practical for widespread deployment.” The MIT supercapacitors stand up well against existing capacitors in several areas, such as how many “charge/discharge cycles” they can go through: they lost not even 10 percent performance “after 10,000 cycles,” a statistic similar to existing supercapacitors. The journal Nature Materials published the team’s research online this week. Chemistry professor at the Catholic University of Louvain in Belgium described the MIT research as “very significant, from both a scientific and applications point of view.” MOFs have many other potential applications, such as in self-shading windows .
