The university of Michigan students achieve recycle lithium battery materials

According to foreign media reports, the Michigan tech chemical engineering students have adopted one thousand years ago ( 世纪 老) Mineral processing method, and discovered the lithium ion battery recycling economical scheme.

the research team used two mining technologies, separation within the battery parts: shell, foil material and anode and the cathode coating.

the biggest advantage is the price cheap, energy saving process. For new batteries, the recycled material and the quality of the original material is also good, and the price is cheaper.

the team saw the opportunity, use of the existing technology to solve gradually highlight challenges ( Battery material scarcity, supply, price, etc. ) 。 He ( She) The gravity separation (with a standard Gravity separation, standard gravity separations) Technology, separate the copper and aluminum, and then using foam flotation ( froth flotation） Reduction of key materials, including: graphite, lithium and cobalt. The mining technology is the most cheap, the infrastructure is already in place.

in order to further promote the research and translational research and commercialization (Michigan tech 转化研究和商业化,MTRAC) Innovation center ( 创新中心) Provide financial support.

in addition, the project also won the United States environmental protection agency (epa) grants, amount of 1. 50000 dollars.
