Lithium-ion cells are increasingly being used as central power storage systems for modern applications, i.e., e-bikes, electric vehicles (EVs), satellites, and spacecraft, they face significant constant vibrations. This review examines how these vibrations affect the batteries’ mechanical, thermal, electrical properties. Vibrations can cause structural issues, such separation of electrodes deformation separators. These problems raise internal resistance lead to localized heat generation. As a result, thermal management becomes more complicated, battery aging accelerates, safety risks arise, including short circuits runaways. To tackle challenges, we need realistic testing protocols that consider combined effects vibrations, temperature, mechanical stress. Improving (TMSs) using advanced cooling techniques materials, e.g., phase change solutions, help alleviate problems. It is also essential design batteries with vibration-resistant materials enhanced integrity boost their durability. Moreover, play role in various degradation mechanisms, dendrite formation, self-discharge, lithium plating, all which reduce capacity lifespan. Our current research builds on insights multiscale physics-based modeling approach investigate interact behavior contribute degradation. By combining computational models experimental data, aim develop strategies tools enhance lithium-ion safety, reliability, longevity challenging environments.

Non-contact laser ultrasonic detection technology provides an innovative solution for evaluating the internal conditions of lithium-ion batteries (LIBs), offering significant advantages in gas defect assessment and structural identification. This study proposes a method defects LIBs based on non-contact system. The system uses pulsed to generate waves, with full-optical probe receiving signals, enabling high-resolution imaging features battery. analyzes key characteristics under different parameters (energy, pulse width, focal length) their correlation defective regions. Through both time-domain frequency-domain analysis features, results demonstrate that signal amplitude attenuation ultrasound media acoustic impedance mismatches can be used precise quantitative characterization regions within offers promising real-time, non-destructive monitoring condition batteries, significantly enhancing battery safety reliability.
