Lithium-ion batteries are being increasingly used as the main energy storage devices in modern mobile applications, including modern spacecrafts, satellites, and electric vehicles, in which consistent and severe vibrations exist. As the lithium-ion battery market share grows, so must our understanding of the effect of mechanical vibrations and shocks on the electrical performance and mechanical properties of such batteries. Only a few recent studies investigated the effect of vibrations on the degradation and fatigue of battery cell materials as well as the effect of vibrations on the battery pack structure. This review focused on the recent progress in determining the effect of dynamic loads and vibrations on lithium-ion batteries to advance the understanding of lithium-ion battery systems. Theoretical, computational, and experimental studies conducted in both academia and industry in the past few years are reviewed herein. Although the effect of dynamic loads and random vibrations on the mechanical behavior of battery pack structures has been investigated and the correlation between vibration and the battery cell electrical performance has been determined to support the development of more robust electrical systems, it is still necessary to clarify the mechanical degradation mechanisms that affect the electrical performance and safety of battery cells.

动态载荷和振动对锂离子电池的影响

锂离子电池正越来越多地用作现代移动应用中的主要储能设备,包括现代航天器、卫星和电动汽车,其中存在持续且剧烈的振动。随着锂离子电池市场份额的增长,我们必须了解机械振动和冲击对此类电池的电气性能和机械性能的影响。最近只有少数研究调查了振动对电池材料退化和疲劳的影响以及振动对电池组结构的影响。本综述侧重于确定动态载荷和振动对锂离子电池的影响的最新进展,以促进对锂离子电池系统的理解。理论、计算、本文回顾了过去几年在学术界和工业界进行的实验研究。尽管已经研究了动态载荷和随机振动对电池组结构机械行为的影响,并且确定了振动与电池电性能之间的相关性以支持更稳健的电气系统的开发,但仍有必要澄清影响电池电性能和安全性的机械退化机制。
