Before It’s News quoted Shenqiang Ren, a professor in the Department of Mechanical and Aerospace Engineering, for a story about a new study that shows how magnetic material can be used to help monitor the amount of life left in a rechargeable battery before it needs to be recharged.
“The main goal of this project was working on the magneto-ionics, which uses ions to control the magnetism of materials,” said Ren, who led the project. “As the lithium ions travel in or out of the material we are using, the material will change its magnetization. We can monitor the magnetism, and this enables us to indirectly monitor the lithium ions – the state of charge. We believe this is a new way to provide an accurate, fast, responsive sensing of state of charge.”
The research paper was published in the Proceedings of the National Academy of Sciences.
