Vibrations and shocks negatively affect the lifespan of lithium-ion batteries primarily by causing mechanical and structural damage to their internal components. This damage leads to accelerated battery degradation and reduced electrical performance.
Key Effects of Vibrations and Shocks:
- Mechanical Degradation: Vibrations induce mechanical stress that leads to the deterioration of the battery’s internal structure. This degradation directly decreases battery longevity.
- Damage to Electrolyte and Electrodes: Shock and vibration can harm the electrolyte and electrode materials inside the battery. This damage may result in structural issues such as micro-cracking or flaking of electrode materials, which impairs proper battery function and shortens its useful life.
- Electrical Performance Impact: Experimental studies have shown that vibration-induced stress affects the battery’s electrical characteristics, including increases in internal resistance and reductions in capacity. These effects contribute to faster performance decline over time.
In summary, vibrations and shocks cause physical damage inside lithium-ion cells that compromises both the mechanical integrity and electrical performance, leading to a shortened battery lifespan. Mitigating these effects often involves using vibration isolation techniques to protect batteries in demanding applications.
