Scientists working at the Applied Physics Laboratory of Johns Hopkins University in the United States have developed cheap sensors (based on intrinsic linkages between easy-to-measure electrical parameters and the internal temperature of the lithium-ion battery cell) , which provides a warning of serious damage (lithium-ion internal battery overheat: takes only a few seconds and if no measures are taken lithium-ion batteries (which are used extensively in electric vehicles, hybrid cars, grid applications electrical, military, and aerospace industries) to conduct temperature adjustments at the interface electrochemical interface between the electrodes v electrolyte.

"We can measure the temperature of the protective layers between the electrodes and the electrolyte of the lithium-ion battery during normal operation," says Srinivasan. "We can also integrate thermal sensors on the surface of these layers (where overheating and catastrophic events occur) to record any changes in temperature that are occurring." .

This inexpensive sensor operates via the simple (positive and positive) electrode coupling of the lithium-ion battery cell, and uses the power supplied from the Lithium- ion, which it is monitoring. With multi-band circuitry, a sensor can monitor multiple cells in a lithium-ion battery pack.

"The new sensor helps manage battery performance and detect unsafe heat conditions at critical moments before a fire occurs , " Srinivasan added. "By integrating technology This (new sensor) into its products, manufacturers, system administrators, and Lithium-ion battery solution providers can increase the level of safety and efficiency of use. Use of their products ".
