Abstract
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.
Highlights
Hooper et al.[37] conducted an experimental study using another type of 18650 battery cell—a nickel cobalt aluminum oxide (NCA) cell—and found that the influence on the cell electrical performance and mechanical properties is minor under vibrations that are commensurate with the vehicle life
The safety and performance of Li-ion batteries are critical to the development of modern spacecrafts, satellites, and electric vehicles
Existing studies have investigated the mechanical behavior of battery pack structures subjected to dynamic loading and random vibrations
Summary
Lithium-ion (or Li-ion) batteries are the main energy storage devices found in modern mobile mechanical equipment, including modern satellites, spacecrafts, and electric vehicles (EVs), and are required to complete the charge and discharge function under the conditions of vibration, shock and so on.[1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17] For example, the Li-ion batteries used to power satellites or spacecrafts must be sufficiently resistant to withstand vibrations, the severe vibrations occurring during launch. As Li-ion batteries become more common, research is needed to determine the effect of standard vibration and shock tests as well as that of long-term vibration on battery cells. Studies on the effect of vibrations and shocks on Li-ion battery cells have been recently conducted.
