Safety component design technology for marine lithium batteries

The Naval Ship Systems Engineering Station of the US Navy's Surface Warfare Center, Kadiluoke, is working with the New Mexico Institute of Mining Technology to use high-speed imaging technology to observe the failure process of lithium-ion batteries and design safe and reliable marine batteries. component.

During the experiment, the researchers created a battery failure environment under laboratory conditions, triggered by pressure explosion, and used Stripe imaging technology to accurately measure the gas density gradient around the battery.

According to NAVSSES Energy Conversion Research and Development Division, emphasis is being placed on the possible impact of the failure of individual cells on other batteries in the vicinity. Future data can be used to develop lightweight protective layers that can reduce battery spacing and protect batteries.

Stripe imaging technology takes 250,000 frames per second to study the relative speed of shock waves and helps researchers track battery explosives. The data will be compared with the dynamic pressure measurement data to determine the amount and speed of gas generated by the battery failure and to identify the shock wave.
