Impendance-based Thermal Runaway early detectgion methodology for Lithium-Ion batteries

As part of the InnoBMS project, our partner CIDETEC has published the article 𝐈𝐦𝐩𝐞𝐝𝐚𝐧𝐜𝐞-𝐛𝐚𝐬𝐞𝐝 𝐓𝐡𝐞𝐫𝐦𝐚𝐥 𝐑𝐮𝐧𝐚𝐰𝐚𝐲 𝐞𝐚𝐫𝐥𝐲 𝐝𝐞𝐭𝐞𝐜𝐭𝐢𝐨𝐧 𝐦𝐞𝐭𝐡𝐨𝐝𝐨𝐥𝐨𝐠𝐲 𝐟𝐨𝐫 𝐋𝐢𝐭𝐡𝐢𝐮𝐦-𝐈𝐨𝐧 𝐛𝐚𝐭𝐭𝐞𝐫𝐢𝐞𝐬” in the International Journal of Electrical Power & Energy Systems.

In this work, Jon Pérez Blanco and colleagues explore how 𝐄𝐥𝐞𝐜𝐭𝐫𝐨𝐜𝐡𝐞𝐦𝐢𝐜𝐚𝐥 𝐈𝐦𝐩𝐞𝐝𝐚𝐧𝐜𝐞 𝐒𝐩𝐞𝐜𝐭𝐫𝐨𝐬𝐜𝐨𝐩𝐲 (𝐄𝐈𝐒) can be used for the 𝐞𝐚𝐫𝐥𝐲 𝐝𝐞𝐭𝐞𝐜𝐭𝐢𝐨𝐧 𝐨𝐟 𝐓𝐡𝐞𝐫𝐦𝐚𝐥 𝐑𝐮𝐧𝐚𝐰𝐚𝐲 (𝐓𝐑) in lithium-ion batteries. The study benchmarks Cidetec’s EIS-based approach against commercial gas-sensing approaches and validates the methodology with real Thermal Runaway tests.

This research contributes to advancing battery safety and developing more reliable and safer Battery Management Systems for automotive and stationary applications.
