New battery technologies that use microwaves may open up new ways for renewable energy conversion and storage. According to foreign media reports, researchers at Purdue University have invented a technology that can turn waste polyethylene terephthalate (a most recycled polymer) into an integral part of batteries .

Vilas Pol, associate professor of Purdue University ’s Department of Chemical Engineering, said: “We used an ultra-fast microwave irradiation process to convert PET (or polyethylene terephthalate) tablets into disodium terephthalate, and Use it as a battery anode material. "
The Purdue University research team tried its method on both lithium-ion and sodium-ion batteries, and collaborated with researchers from the Indian Institute of Technology and Tufts University.
Professor Pol said that although lithium-ion technology currently dominates the market of portable electronic products and electric vehicles, sodium ion batteries are also attracting attention because of their low cost and attractive electrochemical performance, which can be applied to the power grid.
Professor Pol also said: "Since microwave technology has the advantage of fast reaction process, it has applicability in organic reactions and has also received attention in recent years. Using ordinary household microwave devices, PET can be converted into p-benzene in 120 seconds Disodium disoate. "Moreover, Purdue University's technology uses materials that are low-cost, sustainable, and recyclable. (Yu Qiuyun)
