This study investigates the influence of ultrasound on lithium-ion batteries (LIBs) and finds that ultrasound can improve charge transfer, enhance cycling stability and charging rate, and facilitate the formation of inorganic-rich solid electrolyte interphase (SEI) layer. This novel combination of ultrasound and LIBs presents a promising pathway for achieving high-performance batteries.
Lithium-ion batteries (LIBs) stand as a compelling solution to energy source transition in various applications such as the vehicle industry due to their energy and power density. However, the impact of mechanical factors on them remains understudied. Of particular interest is the effect of vibration, an inherent characteristic of vehicles, on battery performance. Ultrasound has been reported to improve mass transfer and surface cleaning, yet its effects on LIBs are still not thoroughly investigated. This study investigates the influence of ultrasound on the solid electrolyte interphase (SEI) layer, resulting in a thin, inorganic-rich layer. The induced SEI layer alteration improves charge transfer, showing enhanced kinetics. We also reveal that ultrasound application enhances cycling stability, maintains discharge capacity at high charging rates, and facilitates inorganic-rich SEI layer creation. This novel combination of ultrasound and LIBs presents a promising pathway for achieving high -performance batteries.
