Solar scientists heart sorrow: electric car batteries will trigger electronic garbage crisis in the future

Tesla announced this year, will be in the super factory Gigafactory 1 develop a battery recycling system. And consumer electronics products, waste management begins with as much as possible to prolong the life of the electric car battery. On-board controller researcher at the institute of university of Birmingham Faraday, the study's lead author Gavin & middot; Mr Harper ( 加文·哈珀) Said, & other; The important thing is that we want to prepare before the problem occurred. Terminates the battery life, they are likely to become a world of one of the ten million tons of electronic garbage. But these so-called fire and hydrometallurgy technology is energy-intensive, produce poisonous gas, and they often poor quality recycled materials. While the challenges are great, but conquer it returns can be very large. Electric cars will be in the human fossil fuel play a key role in the future, but with other technologies, the technology will also pay the price. As the battery configuration and chemical composition of evolution, the development of any recovery technology requires adapter & ndash; — This is also a Faraday institute researchers committed to the development of artificial intelligence system part of the reason, the system can automatically identify and classify various shape and size of the battery. These batteries will overheat and release toxic gas, or would like smart phone battery explosion. Although electric car batteries can be used for up to 20 years, however, as the electric car sales increased year by year, the potential waste battery is huge. When they are no longer suitable for driving, they can be reused to other types of energy storage, such as household battery & ndash; — Companies from all over the world have been test on this idea. ” Colleges and universities, start-up, and even well-known companies, such as tesla are developing all kinds of technology. The article pointed out that the hot end of the cold end heat exchanger sold worldwide in 2017, 1 million electric cars will eventually waste generated 250000 tons of battery, will not be able to deal with the current global recovery infrastructure. In addition to lithium, the electric car battery contains the key metals such as manganese, copper and cobalt. We have been in the last car tyres and fridge to see, if we didn't foresee waste management problems, then produce a mountain of rubbish. According to foreign media reports, the electric car can help save the planet, but their battery recycling infrastructure pose a serious challenge to the world. Harper said that most of the recycling battery by heat melt into the slag, hot end of the cold end heat exchanger and then by chemical separation technology, specific metals such as cobalt. Earlier this year as Earthworks commissioned by a research institute points out, accessible metal batteries are quickly drying up.

a non-profit environmental organization of the Earthworks mining project director Yale & middot; Mulberry pat ( Payal Sampat) Said, how much solar energy mix water valve enterprises also have the responsibility to design can easily remove the battery recycling. We may also use the so-called microbial acid mining technology, and release the key metal rock & ndash; — The scientists also hope to apply this idea to an asteroid mining. ” In the thesis, Harper and his colleagues tried to outline the electric car battery effective waste management infrastructure should look like. Pat wrote in an E-mail, & other; Enterprise must be responsible for the service life of the products, magnesite brick heat storage which means to better design the product, make it easier for the recovery of minerals. From researchers at the university of Birmingham, UK, led a team in the published in nature today ( 自然) Magazine said in a commentary, that is why we urgently need to develop better ways of recycling of electric car batteries, now began to expand the size of the recycling infrastructure. Scientists in a new paper warned that today's electric car batteries could trigger electronic garbage crisis in the future. The lithium ion battery electric vehicle use is made of metal, and magnesite brick heat storage and these metal mining and human caused serious damage to the environment, and the supply of these resources will not last forever. Years of lithium as early as in 2022 is expected to more than the current demand for the output from mines; The design of the electric car battery also no industry standard. The electric car battery voltage is very high, is likely to remove electrocution. But in the end, an on-board controller electric vehicle battery will reach the end of its service life, when they need to be recycled. By 2050, the solar energy mix water valve how much demand for cobalt may also be more than the known global store the authors said, a better approach is to recycle directly, is not to separate returns a metal cathode materials, it is used for new battery. But scale there are significant hurdles, including the cost of recycling and complexity, as well as the processing of the electric car battery.
