Ultrasonic detection offers several distinct advantages over the aforementioned characterization methods for detecting gas defects in LIBs. Firstly, ultrasonic detection can penetrate the aluminum plastic film of batteries, allowing it to monitor tiny bubbles and defects deep inside the battery in real-time.
Moreover, ultrasonic technology allows for real-time monitoring and imaging, facilitating prompt detection of internal defects in batteries. It also enables personalized detection solutions tailored to different battery types.
First AIE probe for lithium-metal anodes. This is the first time that AIE fluorescence technology is being used in the characterization of lithium-ion batteries. An AIEgen with catechol moiety is developed as the solid-state fluorescent probe for graphite anodes.
Direct use of parameters such as ultrasonic amplitude, frequency, and ToF for SOC estimation has accuracy issues, but ultrasonic detection methods have a wealth of data available for analyzing the internal state of the battery. These features make it possible to implement the ultrasonic method using data-driven approaches. Fig. 4.
This fluorescent probe would be a useful method to analyze and predict the failure of LIBs. Uneven lithium intercalation and plating in graphite anodes severely affect the capacity decay and lifetime of lithium-ion batteries (LIBs).
The defects in this battery include misaligned electrodes, folded electrodes, anode material loss, residual bubbles, and implanted copper and aluminum foils. The aforementioned defects can all be intuitively detected, fully verifying the feasibility of using ultrasonic technology for battery defect detection.
