With the rapid development of electric vehicles, safety and reliability lithium-ion batteries (LIBs), as their core energy storage units, have become increasingly prominent. The variation in internal battery pressure is closely related to critical issues such thermal runaway, mechanical deformation, lifespan degradation. non-uniform distribution may trigger localized hot spots or even posing significant threats vehicle safety. However, traditional external monitoring methods struggle accurately reflect data, single-point measurements fail capture true state battery, particularly within modules. This limitation hinders efficient management. Addressing application needs power batteries, this study integrates thin-film sensors into LIBs through integrated functional electrode (IFE), enabling distributed situ during long-term cycling. Compared non-implanted benchmark design does not compromise electrochemical performance. By analyzing evolution data cycling, reveals dynamic patterns changes LIBs, offering new solutions for warnings performance optimization batteries. research provides an innovative approach significantly enhancing systems.
