Perspective—Moving Next-Generation Phase-Field Models to BMS Applications:A Case Study that Confirms Professor Uzi Landau's Foresight

Abstract

Physics-based electrochemical models play a prominent role in the model-based analysis, virtual engineering, and battery management systems (BMS) of lithium-ion and next-generation batteries. Here, we demonstrate the rich physics of phase-field models and convey their potential in BMS applications. Our phase-field model-based optimization framework predicts an impulse-like control profile to reduce capacity degradation. This work was partially inspired by the pulse-charging protocol proposed by Professor Landau in his 2006 work [B. K. Purushothaman and U. Landau, J Electrochem Soc, 153, A533 (2006)]. An open-source framework is shared for predicting the (im)pulse protocol reported.
