The development of advanced Li-ion batteries relies on the implementation of high-capacity Ni-rich layered oxide cathode materials, such as NCM and NCA, among others. However, fast performance decay because of intrinsic chemical and structural instabilities hampers their practical application. Hence, thoroughly understanding degradation processes is crucial to overcome current limitations. To monitor instabilities of electrode materials under realistic operating conditions, the application of nondestructive operando techniques is required. While structural changes of crystalline phases can be studied by X-ray diffraction, microstructural changes (e. g., particle fracture) cannot be easily accessed in situ and are therefore mostly investigated ex situ. Here, we use acoustic emission (AE) measurements to probe a potential next-generation cathode material in real-time. Specifically, we focus on LiNiO 2 (LNO) and demonstrate that AE events in different frequency ranges can be correlated with the formation of the cathode solid-electrolyte interphase and the mechanical degradation during electrochemical cycling.

“…This has been proven by different studies on various battery materials. [40,42,59,62,[65][66][67] AE therefore provides evidence that mechanical degradation is mainly related to the occurrence of the hexagonal H2 and H3 phases in the case of LNO. We assume that both the above-mentioned second increase in hits in the initial cycle and the sudden increase in acoustic activity at high voltages in the following cycles are due to the induced strain and the associated degradation (fracture) behavior.…”

“…Each acoustic signal can generally be distinguished by its set of different characteristic parameters, such as duration, rise time, energy and amplitude, with the peak frequency appearing as the most distinctive AE parameter. [42,59] Figure 3a depicts the peak frequency histogram of the AE signals detected in the first five cycles. Based on the histogram, we divided the acoustic hits into three groups.…”

“…The same applies to the AE 2 hits, which according to literature lie at the border of acoustic activity between gassing and cracking. [40,42,59,62] Because the acoustic activity in the frequency range of AE 2 also decreased to a minor fraction after the initial cycle, we assign it to cSEI formation. Similar results that contradict the classical assignment of AE signals to gassing were observed in the investigation of silicon anodes and deposition of calcium carbonate and zinc phosphate.…”

“…For more details on the AE analysis, the reader is referred to literature. [39,42,43,59,71] Scanning Electron Microscopy (SEM) SEM data were acquired at 10 kV on a LEO-1530 instrument (Carl Zeiss AG, Oberkochen, Germany). An Ar-filled container was used for sample transfer from the glovebox to the microscope, with brief exposure to the ambient atmosphere during sample mounting onto the SEM stage.…”

The rapid commercialization of lithium batteries greatly promotes the development of the electric vehicles, renewable energy storage systems and consumer electronics. The service lifetime and safety of lithium batteries are extremely concerned by terminal customers. Sensor technology is powerful in monitoring the physical and chemical signals of lithium batteries, serving for the state of health and safety warning/evaluation of lithium batteries and guide for future development of battery materials. In this review, the primary concern is the generation mechanisms of different physicochemical signals in lithium batteries. Then, the sensing methods and sensing designs according to different physicochemical signals of lithium batteries is summarized. Finally, some perspectives are provided to guide further development of sensing technology for lithium batteries. This review will greatly accelerate the terminal application of advanced sensors, whether in commercial products or scientific research.
