Our lab focuses on mechanism recognition for commercial batteries, aiming to gain a deep understanding of the key electrochemical mechanisms in common battery systems and explore their differences from laboratory model battery systems. Unlike the idealized coin cells, commercial batteries often face more complex manufacturing processes and operational conditions, including material inhomogeneity, intricate interfacial reactions, and challenges related to large-scale production. Through refined characterization techniques and experimental designs, we aim to uncover the unique reaction mechanisms of commercial batteries in practical applications, providing theoretical support and technological breakthroughs to optimize existing commercial battery systems and develop next-generation battery technologies.
