“…Removing a portion of electrode materials to leave space for internal thermistors could alleviate the uneven pressure caused by sensor implantation [24] but it would reduce the cell energy density and increase the complexity for real-world application. Wang et al [28] designed an integrated functional electrode (IFE), which consists of two single-layer coating electrodes covering a fiber sensor integrated on a substrate (Figure 3d). The substrate ensures that the stacking stress between the electrodes does not squeeze the fiber sensor during cycling, allowing distributed measurement of the temperature inside the cell.…”

Traditional battery management systems (BMS) encounter significant challenges, including low precision in predicting battery states and complexities in managing batteries, primarily due to the scarcity of collected signals. The advancement towards a “smart battery”, equipped with diverse sensor types, promises to mitigate these issues. This review highlights the latest developments in smart sensing technologies for batteries, encompassing electrical, thermal, mechanical, acoustic, and gas sensors. Specifically, we address how these different signals are perceived and how these varied signals could enhance our comprehension of battery aging, failure, and thermal runaway mechanisms, contributing to the creation of BMS that are safer and more reliable. Moreover, we analyze the limitations and challenges faced by different sensor applications and discuss the advantages and disadvantages of each sensing technology. Conclusively, we present a perspective on overcoming future hurdles in smart battery development, focusing on appropriate sensor design, optimized integration processes, efficient signal transmission, and advanced management systems.

Lithium/carbon fluoride (Li/CFx) batteries are highly favored for ultra-high specific energy systems due to their attractive features. However, the significant heat generation poses serious risks including thermal runaway, illustrating the critical need of real-time monitoring during battery operation. Currently, fewer studies have focused on the development of sensors for Li/CFx batteries, especially on the compatibility with embedded sensors. Here, two types of embedded sensors are employed to achieve detection and safety warning. The internal temperature of the Li/CFx battery rises by 8.42 °C at a current rate of 0.1C. Additionally, the embedded atmospheric pressure sensors provide a safety warning with a safety threshold of 0.43 kPa/cm2 before the first destructive venting. Consequently, this nondestructive detection and warning can significantly enhance the safety measures for Li/CFx batteries.
